Native Evergreen Shrubs and this Year's Project

After getting myself all setup on Cornell Lab's YardMap, I realized that while we'd made incredible progress in landscaping the yard and providing biodiversity, we hadn't gone as far as I'd thought. "Lawn" still makes up a large percentage of our property. This means it's time for another project. Or more precisely to circle back to a project from yesteryear and complete it as originally envisioned.

The initial mission, better layering. In particular find some shrubs.

But what kind of shrubs?

We already have lots of Serviceberry, and we have Highbush Cranberry, Pagoda Dogwood, Nannyberry, Staghorn Sumac, and Black Chokeberry.

Something new. Something different. Something with texture. Something to add interest in the winter.

I began searching. I spent a lot of time on the WI DNR's Natural Communities site.

A list of possibilities began to form: Ninebark, New Jersey Tea, Winterberry, Blueberry, Juniper, Red Osier Dogwood, Witchhazel, American Filbert...

I began searching for native evergreen shrubs. This was hard. Perhaps impractical. Perhaps evergreens don't like being shrubs.

I had found two: Juniperus Communis and Juniperis Horizontalis.

In further searching I encountered "Eastern White Cedar". I looked at the latin name, Thuja Occidentalis. How could this be? I knew Red Cedar to be Juniperus Virginiana. Of course, Red Cedar is actually a juniper tree, I read more. American Arborvitae.

"Arborvitae? Those silly hedgerow-looking evergreen trees that people plant to make privacy fences?" I thought.

I began looking at cultivars for all three: Common Juniper, Horizontal Juniper, and American Arborvitae.

I've ruled out Horizontal Juniper as I'm not looking for ground cover, but the options available for the other two are really interesting.In the end, it will probably come down to availability and selecting which ever will look best next to the Red Osier Dogwoods, I intend to plant.

An Understory Story

Those who have had a chance to read The Living Landscape by Rick Darke and Doug Tallamy, are aware of the importance of layers in a landscape. The book breaks landscape into a essentially 4 layers: Canopy, Understory, Shrubs, and Herbaceous.

Many backyard landscapes have a Canopy (a tree or two) and a Herbaceous layer (your flowers and grass). The current state is that a layer in between the two may be relegated to some evergreen bushes planted up against the house. It's possible to create a more diverse and interesting Understory.

Many plants fit somewhere between the category of Shrub and Understory. Two of our neighbors have large Maples (ie Canopy) along these sides of the yard, we decided to plant an Understory of Eastern Redbud, Pagoda Dogwood, Allegheny Serviceberry, and Highbush Cranberry. Our Understory provides excellent white and pink color in the spring and in a few weeks, we expect to have vibrant fall colors.

Most importantly, our Understory provides cover and food for wildlife. Early in the summer the Serviceberries provide fast food for our Eastern Bluebirds who found competition from American Robins. Now at the end of summer, the Highbush Cranberries are red, the Dogwood and Sumac fruit is ripe. The ripe fruit has brought back our Eastern Bluebirds, attracted a pair of Northern Cardinals, and yesterday a Brown Thrasher came to visit.

This part of our yard is popular with the Eastern Gray Squirrels, the Black Capped Chickadees, Jays, and Thrushes.

Biodiversity Timeline

Let's talk a little bit about biodiversity. Biodiversity is a concept related to how many different species are part of a particular community. In this particular case, how many different species are part of our yards. In nature, the amount of life a place can sustain, the more healthy it is considered. In other words, high biodiversity and an ecosystem's health are directly related. The wonderful thing about our yards, is that we as the stewards have direct control over how biodiverse our property is. If we choose to maintain a homogenous monoculture of turf grass, then we elect to keep biodiversity low. If we choose to plant a variety of flowers, grasses, shrubs, and trees, then we elect to increase the yard's biodiversity. Here's our biodiversity story so far.

2011

We moved into our home in April of 2011. The yard was fairly sparse, noteworthy plants included Siberian Iris, Tulips, Daffodils, and Asiatic Lilies. The yard had no trees and two ornamental shrubs. Its diversity is documented in the table below.

Flowers	4
Grasses	0
Shrubs	2
Trees	0

I immediately began to increase the yard's diversity focusing primarily on extending the existing flower bed and adding some shrubs.

End of Spring 2011

Flowers	13
Grasses	2
Shrubs	4
Trees	0

In the spring of 2012, we renewed our focus on adding native plants. We added trees to the yard in 2012, and it was the first year we started keeping track of our animal diversity. We wanted to see the impact the new plants had on the ecosystem of our yard.

In 2013, we spent some time trying to dig out and eliminate the non-native plants with only some success. We also added a couple more trees and replaced some shrubs which had been chewed back by the rabbits.

From what we can tell so far, it appears that as we increase the diversity of the plant life in our yard, the diversity of the animals which come to visit increases as well. Between the flowers, butterflies, birds, and shrubs, we have interesting colors in our yard from May through October. And while the winter has less visual interest, the regular bird traffic provides more visual appeal than what the yard would have otherwise.

Here's a list of a the current plant species which have been planted intentionally in our yard:

Flowers:
• Blue Lupine
• Blazing Star
• Obedient Plant
• Bee Balm
• False Indigo
• Cardinal Flower
• Black Eyed Susan
• Purple Coneflower
• Prairie Coneflower
• Columbine
• Butterfly Milkweed
• Pre-existing Tulips
• Pre-existing Daffodils

Grasses:
• Big Blue Stem
• Little Blue Stem
• Prairie Dropseed

Shrubs:
• Serviceberry
• Black Chokeberry
• Pagoda Dogwood
• Staghorn Sumac
• Highbush Cranberry

Trees:
• Bur Oak

• Eastern Redbud

Plant by Habitat: Boreal Forest

Over past few weeks, we covered a variety of natural communities found in the Upper Midwest including: Deciduous Forests, Prairie, Pine Barrens, and Oak Savannas. Each post is intended to help readers select groups of plants which grow together naturally. This post will focus on the trees and shrubs which make up the coniferous and boreal forests of the Upper Midwest.

Red Breasted Nuthatches enjoy peanuts in addition to conifer seeds and insects.

The key feature of a coniferous forest, are of course the coniferous trees. In the Upper Midwest these forests are composed of dense stands of Eastern White Pine (More on Native Pines), White Spruce (More on Native Spruce), and/or Balsam Fir. When grown in close proximity these trees form a dense canopy which creates shade below throughout the year. These trees are home to native bird species such as Pine Siskins, Red Breasted Nuthatches, and Pine Grosbeaks; all of which will feed on the seeds of these plants by extracting their meal from the cones produced by the trees.

Black Hills Spruce is a subspecies of White Spruce which is generally easy to find.

These stands of Pine, Spruce, and Fir may not be entirely homogenous; other trees which can be found in these forests include: Hemlock, Paper Birch, and Quaking Aspen. Paper Birch is an attractive tree with white bark which many people choose to plant in their front yard. Quaking Aspen is another option; it grows remarkably quickly. Both the Paper Birch and the Quaking Aspen are deciduous, but neither grow a large shade- providing canopy (like an Oak or Maple would).

If the tree cover is dense, the understory will be sparsely populated, but some shrubs found in the understory include: Serviceberry, Witch Hazel, and Blueberry. Blueberry can be particularly tricky to grow as it requires a low soil ph ideally between 4.0 and 6.0. If your yard has much limestone, the ph is likely to0 high. Serviceberry and Witch Hazel provide interesting color at opposite ends of the year. Serviceberry will bloom with white, showy flowers in the very early spring. Witch Hazel will turn vibrant yellow in the fall.

Our Alleghany Serviceberry's showy spring blooms.

In the forest you are unlikely to come across much grass, however you may find other forms of ground cover including Wild Sarsaparilla and Bunchberry. I haven't seen much of either commercially available, so if you are looking for something to put down other than turf grass, you could consider Pine straw or needle mulch, stone, and/or try some ferns such as: Christmas Fern or Lady Fern.

Coniferous forests as described in this post are common in Minnesota, Wisconsin, and Michigan than in the rest of the Midwest. If you are unsure of these plant selection, please visit your state's DNR or Forestry website for information on coniferous forests in your state. Happy planting!

Plant by Habitat: Deciduous Forest

A recent theme for many posts has been planting by habitat, whereby we've tried to identify native plants which can be planted together to simulate natural communities. For most of these communities trees are the backbone with shrubs and other plants being the guts. Depending on what you already have in your yard, you could be off to a good start. This post will focus on the Deciduous Forest.

A number of tree species which can be easily found commercially may already be planted in your yard. In the Upper Midwest, trees common in yards and the forests include: the Sugar Maple, Red Maple, and White Oak. These trees are excellent shade trees for your yard, and they support a host of wildlife. Common forest birds which are likely to be attracted to these trees include: Red Bellied Woodpeckers, Downey and Hairy Woodpeckers, Black Capped Chickadees, White Breasted Nuthatches, Blue Jays, and Yellow Bellied Sapsuckers. Maple sap may even be eaten by migratory birds who take advantage of the Sapsucker's drill holes including Ruby Throated Hummingbirds. An Oak's acorns will attract a variety of other kinds of critters including Squirrels and Chipmunks. Mor e information on these trees can be found in earlier posts; Information on Oaks or Information on Maples.

Red Bellied Woodpecker comes down for a visit.

A number of other trees make up the skeleton of the deciduous forest; note that some of these trees may be more difficult to find than their Oak or Maple counterparts. These trees include: American Beech, American Elm, Basswood, Black Cherry, and Shagbark Hickory. Black Cherry will attract certain species of caterpillar which are eaten by birds, and the fruit of the tree will also attract our feathered friends including some which may not come as regularly to feeders such as Orchard Orioles. The Black Cherry is also very attractive when in bloom. The American Beech produces a nut which is smaller than an acorn. Beech nuts are eaten by Red Headed Woodpeckers, the Tufted Titmouse, and Red Breasted Nuthatches. The Shagbark Hickory's bark is an excellent hunting ground for birds like Nuthatches and the Brown Creeper as the bark is home to many insects.

Once you've selected some variety of trees for your forest planting, you'll want to move on to the understory. The Mapleleaf Viburnum is a good Viburnum to consider when looking for forest shrubs. This plant can provide excellent cover and protection for birds and small mammals. It may produce abundant fruit eaten by birds like Grouse or Turkey. American Witchhazel has showy yellow flowers in the fall. The fruit produced by this shrub is eaten by Northern Bobwhites, Grouse, and Eastern Cottontail Rabbits. Witchhazel can be grown as a shrub or managed to be grown as a small tree.

Birds like this Gray Catbird enjoy dense shrubby cover.

If providing dense cover with trees and shrubs, you may encounter a challenge in selecting flowers which will tolerate the shade. Here are some suggestions for native flowers which you may be able to find for this habitat: Jack in the Pulpit, Large Flowered Trillium, and Virginia Bluebells. Trillium has a showy white flower which appears in May or June. The Bluebells grow low to the ground and have small blue flowers which present early in the year in April or May, around the same time the Jack in the Pulpit flowers.

If interested in having a forest getaway, this post should be a good place to get started. Many other native plants also grow in the Deciduous Forest, ask your local nursery for more information. Happy planting.

Plant by Habitat: Pine Barrens

In the previous Plant by Habitat post, we identified some plant species to combine in a yard to create an Oak Savanna, in this edition, we'll describe some plants which are found in Pine Barrens.

Pine Barrens are habitat found in the Upper Midwest in parts Minnesota, Wisconsin, and Michigan. Pine Barrens are home to coniferous trees like Jack or Red Pine which do well in acidic soils. Poor soil quality and highly acidic soil are characteristics of the barrens which impact what types of plants grow in these communities.

Sandy or acidic soils in your own yard may prompt you to consider planting species found in pine barrens together. The first step for creating your Pine Barren is to find the correct tree species. First you'll need Pines, and you'll start with Jack or Red Pine. You can also consider Oaks, which are commonly also featured in Pine Barrens.

Once the trees are selected, you'll want to move onto the shrubs and understory. A pine barren doesn't support much of an understory, hence the name, but certain shrubby plants are found amongst the pines. These plants include two which are commercially available and which strongly support wildlife: the American Hazelnut and the Low Bush Blueberry. Hazelnuts are eaten by a variety animals including small mammals, Wild Turkey, and Grouse. The sweet blueberries are enjoyed by people as well our animal neighbors.

Lupine is an attractive ground cover found in the Pine Barrens.

Much like the Oak Savanna, this habitat was filled with prairie grasses and wildflowers. Plants common to the Pine Barrens include June Grass, Little Blue Stem, Blazing Star, and Blue Lupine. The Lupine is of particular importance to the habitat. It is a legume and puts nitrogen back into the soil for use by other plant species. It is also the host for the endangered Karner Blue Butterfly whose caterpillars feed on the leaves.

Endangered butterflies may not be the only interesting visitors to your lawn if you successfully establish a Pine Barren. By planting Jack Pines and Blueberries in particular you may help the recovery of the endangered Kirkland's Warbler as your yard may become an attractive nesting site.

Plant by Habitat: Oak Savanna

Recently I posted information about native Oaks and later realized it might be helpful to have some information not just about which plants are native vs invasive, but it may also be helpful to have some sense of which native plants actually grow together naturally. Over the next couple of weeks, I'll do some "Plant by Habitat" posts to hopefully help inform decisions about which native plants to purchase together.

The Oak Savanna is a type of habitat which features large Oaks with room to really spread their limbs. These savannas were once found throughout the Midwest and served as the boarder between the prairies and grasslands of the Great Plains and the forests of the Eastern United States. A variety of Oak species were found in the savannas including: Black Oak, Bur Oak, Northern Red Oak, and White Oak. These trees can be found commercially available, and if you are interested in planting your own Oak Savanna, an Oak is a good place to start.

That said other trees and plants could be found in the savannas. Shagbark Hickory and Black Cherry are also excellent savanna trees to consider. Black Cherry is particularly interesting as it is a host for a variety of caterpillars and its fruit is eaten by many birds.

Once you've selected your trees, you are on to deciding what will go in the understory. You will need to decide exactly how wide open your savanna will be. Some savannas would have had some shrubby understory if less frequented by fire, but those more frequented by fire would have had more prairie grasses and flowers.

Highbush Cranberry can be really attractive in the fall.

My favorite shrubs to consider are Viburnums. American Highbush Cranberry, Nannyberry, and Mapleleaf Viburnum are interesting choices. Viburnums tend to be pretty tolerant of most growing situations, have attractive foliage in the fall, and they tend to be pretty easy to find commercially. These are really great shrubs, we have 4 Highbush Cranberries and 2 Nannyberries in our yard. Pagoda Dogwood, Hazelnut, and Staghorn Sumac are also good choices. The Sumac and the Dogwood are fairly shade tolerant, so they may not be best suited to an open savanna habitat, they do however produce fruit which can be eaten by birds. The Hazelnut will produce nuts which fall to ground and are eaten by mammals like Gray, Red, or Fox Squirrels but also by Wild Turkey and Ruffed Grouse.

By this point, you have a tree or two selected; you've decided on a shrub or two, and now you need something to cover the ground. You are now looking for plants which do well when burned back semi-regularly. You are going to want some prairie grasses, some of the easiest species to acquire are Little Blue Stem, Big Blue Stem, and Prairie Dropseed. The flowers for an Oak Savanna can be more difficult to find but they include plants loved by butterflies such as Purple Milkweed and Common Milkweed. Shooting Star, Wild Indigo, and Wild Columbine are also reasonably easy to find as plugs or seeds.

We put in a few indigo plants last year which were not by the rabbits.

With these plants in place, a lawn would be replaced with a small Oak Savanna. It would be fairly biodiverse in terms of plants species and be able to support a number of bird and butterfly species. If you live in the Midwest (see map), there is a reasonable chance your yard was once in fact part of the Oak Savannas. The Oak Savannas were replaced with farmland and then the farmland with subdivisions, so why not give part of your yard back and return it to nature, after all the birds and the butterflies are the ones who have to live with it.

Native Ornamentals - Three Plants to Consider

Many homeowners looking for ornamental shrubs or trees look to flowering crabapples or magnolias as way to add color to their landscaping. Note that some of these plants maybe native North America, but many are native Asia. Three plants to consider when looking for something to brighten your yard in early Spring are: the Eastern Redbud, Serviceberry, and Red Chokeberry.

Eastern Redbud

Eastern Redbud in our yard early May 2013

This is the plant we get the most questions about from passersby and from our neighbors. We planted it two years ago, and in the spring it's a brilliant pink color. The vibrant buds last about a month, and other than the flowers which bloom in the summer in our yard, it's the most decorative plant in our yard. It's one of the few sources of color in our yard until the weather turns warmer. Spring in the Upper Midwest can be gray, green, wet, and even cold, but this tree makes things feel a little warmer and more exotic with its blazing pink buds. Ultimately it will stay an ornamental size growing between 15 and 30 feet high; this makes it an excellent choice when considering native ornamentals.

Allegheny Serviceberry

The White Flowers of the Serviceberry

Amelanchier laevis is a good example of the beauty Serviceberry can bring to your yard. Many varieties of serviceberry are native to North America, and a few are native to Europe or Asia. These plants can grow lowly and present like a bush, while others grow more like a shrub or tree. This Allegheny Serviceberry was planted last year in our yard and flowered almost immediately. The flowers grow in showy white bunches, and the subsequent fruit drew the attention of Robins and Cardinals. It did so well last year, that we are looking to purchase two more this year. The white blooms of the Serviceberry added a nice splash of color at the back of our wildflower garden which in May was otherwise entirely green. This plant will grow to a size similar to the Redbud, maxing out at 12 to 25 feet.

Red Chokeberry

These were the Chokeberry flowers before the rabbits ate our beautiful shrubs.

Red Chokeberry is another option which like Serviceberry will flower with white blooms in the early Spring. The flowers will attract pollinators early in Spring to your garden, and later in the summer the plant will produce red berries. The plant's foliage turns a vibrant red in the Fall, so it provides good color for landscaping two times during the year. This plant is more of shrub than the previous two and its maximum height is 12 feet. This is also a plant which you may want to place a guard around. Two years ago, we planted two Red Chokeberries, and after two long winters, the rabbits had successfully chewed both down to stubs.

These are only a few examples of native plants which can be used as ornamentals. If you are looking for early Spring color to welcome in Summer, they are excellent choices. Happy planting.

This Year's Plan

Below you'll find a couple of photographs of our lawn from when we first purchased our home. You'll notice the stark absence of trees. From talking to the neighbors, we've been told that the yard once had Red Cedar in the front and back, but currently we have none. So the big task this year will be planting some trees.

When I sat down with these images over the winter, I realized exactly how jealous I am of P. Allen Smith and his fancy digital whiteboard. I started with a sketch pad and noted the places in the backyard whereby planting a tree would be next to impossible. I didn't want to shade out our wildflower garden, and I'm not convinced that planting a tree in the shady part of the yard will work well either. So most of the tree planting will need to be in the front yard.

The front yard will host four trees. The north end of the yard will have a wind-block made of Eastern White Pine, Red Cedar, and American Larch. Conifers are native to the boreal forests of North America and provide excellent shelter for the birds. On the south side of the front lawn, I plan to add a Red Oak. The acorns will attract birds and other critters, and oaks are also popular with birds that eat insects like woodpeckers and nuthatches. I'll add a couple of Nannyberry Viburnums near the oak tree as well. Lastly, I still wanted to plant something in the backyard to give the birds who visit our feeders a good place for perching, so something small like an Eastern Red Bud seems like a good choice.

The wildflower garden did pretty well last year, but there were a number flowers we did not get a chance to plant. The bed will be extended and widened, and the following flowers will be added: Lance-Leaf Coreopsis, Cardinal Flower, and Bee Balm. There is also a small, currently unused bed, near our air conditioner in which we found a single Columbine growing last summer. I've purchase more Columbine to add to this bed this year. We're hoping the addition of Bee Balm, Columbine, and Cardinal Flower will help our yard attract more butterflies and hummingbirds.

The shady corner is home to our compost bin which can be a bit unsightly. We had good luck with the Highbush Cranberry Viburnums and the Pagoda Dogwood which we added to this part of the yard last year, so we plan to add two more Highbush Cranberries. We will also plant some Ribes, particularly Coralberry, a type of Currant as well as a Highbush Blueberry. This corner is becoming the understory for our neighbors' oaks and maples.

The interesting part about our landscaping so far is that coupled with the different types of bird feeders, our miniature biomes attract different types of birds. The feeders full of sunflower seeds and peanuts are nearest the shady corner. Blue Jays, Downy Woodpeckers, and Black Capped Chickadees can be found in this part of the yard. Whereas the American Goldfinches and Dark Eyed Juncos can be found nearer the wildflower garden at the nyjer feeder. With some careful planning and clever plant selection, you too can create small habitats for the wildlife in your yard.

Last Year's Accomplishments

When I started this blog, I wrote a piece on what we started with. This was just a quick summary about what the lawn was like when we purchased our home. Today, I'd like to take a moment to reflect on our accomplishments from last year and touch on some lessons learned.

Before purchasing the house, just after we had gone to see it for the first time, I started sketching out the many ideas I had about what I could do with the yard. Shortly after moving in, sometime in mid-April, I began digging into the sunny corner in the back, removing the sod, and extending the existing flower bed. I had started some seed indoors and by late April, I had some Blue Lupine seedlings in the house. I decided it was time to plant, so I brought my seedlings out with some seed for Purple Coneflower, Black-Eyed Susan, False Indigo, Sky-Blue Aster, and Butterfly Milkweed. In May we had frost almost everyday for the first two weeks. I had planted too early.

I ended up purchasing a number of plugs from Kopke's Greenhouse to replace the plants which I had lost. Our flower bed was full of Little Blue Stem, Purple Coneflower, Black-Eyed Susans, Prairie Coneflower, Blue Lupine, False Indigo, and Butterfly Milkweed. Unfortunately, I didn't put up any fencing. The Lupines and Indigo were chewed down to the ground regularly, and the rabbits even appeared to have tried eating the Butterfly Milkweed.

By Mid-June, I was feeling rather dispirited with the flower garden, so I turned my attention to shrubs. I decided that the shady corner needed the most work. In the morning, it is largely shaded out by our neighbor's Sugar Maple, and for part of the afternoon, it's shaded by another neighbor's Oak. We set up the compost pile here and planted two Highbush Cranberries and a Pagoda Dogwood. These shrubs took right away and have been great additions to the yard. In fact, they stood up to a wave of Japanese Beetles.

By July, we finally had some blooms in the flower garden. In particular, the Prairie Coneflower was spreading like a wildfire. I decided it was time to add some shrubs to the sunny corner and planted two Red Chokeberries and two Saskatoon Serviceberries. While purchasing the shrubs, I stumbled onto some discounted Big Blue Stems, Obedient Plant, and New York Aster. The flower bed needed to be extended again. Unfortunately, once again the rabbits took over. They chewed down the Chokeberries and Serviceberries as well as the Asters. I ended up putting fencing around the bushes.

By August, the Black Eyed-Susans and Purple Coneflowers had bloomed, and some of the False Indigo started to make a comeback, however it never got taller than 4 inches or so. The Butterfly Milkweed flowered, and a handful of Lupines remained. Fall came, and only the Chokeberries fruited. While there was a certain element of disappointment to the year, I was quite excited that anything had flowered at all. One wintery day during January, I noticed Dark-Eyed Juncos in the garden picking at the remains of Black-Eyed Susans and Big Blue Stem, and it was then that I knew my experiment had been successful.

Today, we had our first Robin in the yard, and with Spring just around the corner I anxiously await the return of the plants. I'm curious to see which plants will return, assuming that some which I have written off will in fact return. But before they start popping up, I still have some work to do. I'll discuss that on Friday.

Everyone Loves Viburnums

People looking for shrubs may not be sure what plants they'll need and may not be sure what plants are native. I've been particularly impressed by the genus viburnum. The Upper Midwest is home to Highbush Cranberry, Nannyberry, Maple Leaf Viburnum, and Arrowwood Viburnum. The viburnum genus can be found throughout much of the Northern Hemisphere, and these deciduous shrubs fruit with small berries. I've added some pictures of the Highbush Cranberries we planted last year.

Highbush Cranberry(viburnum trilobum) is probably the best known of the viburnums. It can be easily confused with its European cousin and is generally available at many nurseries. You can likely find it in its typical/natural form but also comes in a compact form. It blooms with small white flowers, and in the fall, the leaves turn crimson. The shrubs berry red, if they berry at all. The plants are gendered and in order to get berries, you'll need both male and female plants.

Nannyberry(viburnum lentago) will also flower with white blooms like the Highbush Cranberry. Nannyberry is shade tolerant, and we plan to plant it in our shady corner near our Pagoda Dogwood. The fruit start light green and become blue-ish later in the year. These berries will persist through the winter and should attract birds.

Maple Leaf Viburnum(viburnum acerifolium) is another option you may want to consider. The leaves of this shrub may be broader than the previous two viburnums discussed. White flowers on this shrub give way to red berries which become blue. The green foliage turns purple in the fall. This viburnum is less shade tolerant than the Nannyberry but does require some shade to grow well. This viburnum seems to be more difficult to find commercially when compared with the Nannyberry or the Highbush Cranberry.

Arrowwood Viburnum(viburnum dentatum) has a number of available cultivars including: Blue Muffin and Autumn Jazz. This viburnum will do well in partial shade and produce blue fruit in late summer. The flowers are white like the other viburnums, and this plant is tolerant of Black Walnuts and clay soils.

Generally speaking the viburnums are pretty hardy and low maintenance. Because of their flowers and fruit, butterflies and birds may be attracted to them as well. If you don't already have some, I'd recommend planting viburnums. They are pretty great, and I'm sure you'll see why everyone loves viburnums.
