Native Pollinator Trees, Shrubs, and Flowers for Virginia and Appalachia

Supporting native pollinators can be so much more than planting monarda and milkweed! It can be more than trying to create a wildflower meadow. It can be targeted at your own favorite moth or cast a very wide net. This is a collection of high quality trees, shrubs, and flowers for supporting native pollinators in Virginia and Appalachia, for creating a unique garden, or just beautifying the semi-wild areas along your property. The amount of quality habitat for insects and pollinators has been dramatically reduced by regular spraying and mowing along roadsides, fence lines, power easements, and sunny margins. This creates an opportunity to make a big difference at least at the micro-level by planting food for these creatures upon which all of life depends and which are a lot of fun to watch!

First Principles

Use native plants – The more I learn, the more critical I discover this to be. Our native pollinators co-evolved with the native flora and fauna of North America. Although some are generalists, like the carpenter bee and bumble bee, many depend on a very few plants in tight mutualistic relationships. In other words, without one you don’t get the other. The generalist pollinators will often feed on exotic ornamental flowers, but these flowers don’t provide optimal nutrition for them. Others, like the monarch butterfly have more specific needs. Once upon a time, those needs were abundantly met across North America. Now, we’ve designated their larval host and nectar source plants as weeds and this once-common butterfly is endangered. I’ll share more on supporting monarchs. While the monarch migrates truly vast distances, some native pollinators only travel a hundred feet and can be helped by your little garden even if we aren’t able to as a society decide to conserve the monarch butterfly’s habitat.

Vertical Layering & Browse Protection

Use a mix of flowering herbaceous perennials, shrubs, and trees – Vertical layering is often overlooked for maximizing benefits, especially in a small space. And also it’s just pretty! Shrubs and trees stand a chance against deer and goats once they get tall and big enough, and will need to be protected early on. Beyond that, another way to defend against excess deer browse is to plant more options. Rather than only planting deer-resistant plants, try planting lots of plants for them to choose from without restricting yourself to the deer-resistant plants. This is another way we’ve unwittingly limited the food and habitat options for many invertebrates. A mature landscape should be able to handle being grazed, especially by deer who won’t stand in one place to graze. Read 36 Deer Foods Every Hunter Should Know for more insight on their eating habits. If you’re planting near walnut trees, you may want to avoid juglone-sensitive plants. Here’s a handout on landscaping around walnut trees.

Native Pollinator Trees

Listen to the podcast for more in-depth information about these plants. Serviceberry (Amelanchier arborea and Amelanchier canadensis), fringe tree (Chionanthus virginicus), pagoda dogwood (Cornus alternifolia), eastern redbud (Cercis canadensis), sassafras (Sassafras albidum), staghorn sumac (Rhus typhina), American plum (Prunus americana), persimmon (Diospyros virginiana), pawpaw (Asimina triloba), hawthorn (Crataegus sp.), and other native fruit trees. If you want fruit production, choose trees with a succession of flowering so that your native bees will have a chance to get established and do your pollinating for you. If you want to learn more, check out permacultureorchard.com and Stefan Sobkowiak’s YouTube channel. He’s a great permaculture teacher.

*Update: In the first edition of this post, American hornbeam (Carpinus caroliniana) was listed with the larger trees. I didn’t do my research on that one! But it is actually a small understory tree that is so exciting I can’t believe I missed out on it. (Skip the European C. betulus variety which grows more like a bush). It’s got a gorgeous form with this smooth ropy trunk that gives it the nickname Musclewood, mesmerizing wing-seeds, vibrant lime and deep green foliage, and attracts both birds and butterflies, as well as being a larval host for the Eastern Tiger Swallowtail, Striped hairstreak, Red-spotted Purple, Tiger swallow-tail (according to Lady Bird Johnson Wildflower Center), and the Io moth. Oh, I wonder if that means your little ornamental tree will be covered with caterpillars chewing away? Anyway, plant three of them! Or more! Nature plants in groves. The wood makes great small tool handles, but isn’t used commercially, so a nice niche item for hand craftsmen.

Larger trees include sourwood (Oxydendrum arboreum), black locust (Robinia pesudoacacia), wild black cherry (Prunus serotina), tulip poplar (Liriodendron tulipifera), red maple (Acer rubrum), sugar maple (Acer saccharum), black gum (Nyssa sylvatica), northern red oak (Quercus rubra), white oak (Quercus alba), yellow buckeye (Aesculus flava), basswood or American linden tree (Tilia americana). Many of these large trees are larval hosts primarily, although some definitely contribute high quality nectar to the forest community.

Flowering Pollinator Shrubs

Listen to the podcast for more in-depth information about these plants. Buttonbush (Cephalanthus occidentalis), snowberry (Symphoricarpos albus), coralberry (Symphoricarpos orbiculatus), Carolina buckthorn (Frangula caroliniana), marshmallow hibiscus (Hibiscus moscheutos), maple-leaf viburnum (Viburnum acerifolium), southern arrowwood (Viburnum dentatum), meadowseet (Spiraea alba), steeplebush (Spiraea tomentosa), white meadowsweet (Spiraea alba), the chokeberries (Aronia arbutifolia and A. melanocarpa), ninebark (Physocarpus opulifolius), witch hazel (Hamamelis virginiana), American hazelnut (Corylus americana), bottlebrush buckeye (Aesculus parviflora), and elderberry (Sambucus nigra ssp. canadensis).

*Update #2: In the first edition, I made a last minute addition to the large tree category, something I heard while listening to Kelly Gill of the Xerces Society on the Pinelands Nursery podcast. It’s not her fault I didn’t do my research, but this tree is not actually quite maybe native to Virginia this far south, and it’s really actually a small tree/shrub. Duh! I actually took one look at the flowers and became so enchanted, I stopped looking (because Lady Bird Johnson said it was native to Virginia)! ha ha ha. The tree is the pussywillow, or Salix discolor. It blooms early as do all the willows, and is easy to establish according to Kelly. It is a champion nectar provider with a whole host of specialist pollinators who feed the pollen to their young! The Virginia Native Plant Society says on their Facebook page, “Pussy willow, (Salix discolor), is listed as native to Virginia, but known definitively from only a single site. The Digital Atlas of the Flora of Virgina says: ‘Known from just a single station in Virginia, a calcareous spring marsh in Augusta Co. […] This northern shrub willow is also frequently planted for ornament, but is not known to escape here.'” So, plant it as you will.

Perennial Pollinator Flowers

Since most of these are considered weeds, you might want to make sure it’s clear that your planting is intentional, maybe with defined beds, maybe with signs, and by planting masses or drifts (a lot of each kind of flower), which looks really good anyway!

Listen to the podcast for more in-depth information about these plants. Dwarf goldenrod (Solidago nemoralis**+), showy goldenrod (Solidago speciosa*+), any native (non cultivar) goldenrod that you can manage (more on this below!), asters (smooth blue Symphyotrichum laeve,* New England S. novae-angliae,* New York S. novi-belgii*), butterfly weed (Asclepias tuberosa**), common milkweed (A. syriaca**), swamp milkweed (A. incarnata), (choose the milkweed native to your location and suited to your growing conditions), bee balm (Monarda fistulosa,** M. didyma), purple giant hyssop (Agastache scrophulariifolia**), fall phlox (Phlox paniculata), echinancea (E. purpurea*), spring beauty (Claytonia virginica), rose vervain (Verbena canadensis or Glandularia canadensis), liatris (L. spicata*), Virginia lion’s heart or obedient plant (Physostegia virginiana), black-eyed Susan (Rudbeckia fulgida), boneset (Eupatorium perfoliatum*), Virginia mountain mint (Pycnanthemum virginianum), Joe Pye weed (Eutrochium fistulosum* very tall!), spotted Joe Pye weed (Eupatoriadelphus or Eutrochium maculatus*), New York ironweed (Vernonia noveboracensis* tall), lanceleaf coreopsis (Coreopsis lanceolata), wild indigo (Batpisia tinctoria), smooth penstemon (Penstemon digitalis), New Jersey tea (Ceanothus americanus), wild ageratum or blue mistflower (Conoclinium coelestinum can become invasive).

Noteworthy Pollinator Vines

Coral honeysuckle or trumpet honeysuckle (Lonicera sempirivens), yellow passionflower (Passiflora lutea), purple passionflower (Passiflora incarnata), virgin’s bower (Clematis virginiana), trumpet vine (Campsis radicans) often considered invasive–plant with care, make sure you have some natural checks on its spread such as a wide mowed area around it or dark shade on one side of it.

If you plant passionflower, you will probably attract carpenter bees, the obligate pollinator for this native flowering vine. If this worries you, first, look forward to the fruits of their labors–the fruits are edible and were harvested by First Nations peoples, a true delicacy to some today, and wouldn’t be possible without Xylocopa virginica, the humble carpenter bee is only pollinator that can do the job. This is a great article written by someone who grew up eating maypops, including lots of how-to’s, photos of the flower, fruit and plant in various stages, even info about the special butterfly it exclusively hosts, the Gulf fritillary! Such a beautiful creature, and so interesting – it looks like a stinging caterpillar but actually isn’t. Too bad we’re too far north to see it.

This quote from Mr. Smarty Pants from the Lady Bird Johnson Wildflower Center about eating passionfruit, is choice:

“The seed-filled pulp of the fruit is the part that is eaten. The fruits of some individual plants are tastier than those on other plants of the species. Some people do not care for the taste at all. There probably is not an Emily Post-like way of eating maypops, but children just seem to know that you should break them open – they often make an audible pop in the process – and squeeze the contents, seeds and all, into your mouth where you strain and swallow the sweet-tart pulp and spit out the glob of seeds. Dainty no, delicious yes.”

– from Edibility of Passiflora incarnata at wildflower.org.

Second, you can put out carpenter bee houses to prevent them from nesting in your wood siding or other structures, which I can testify works great! Put your houses out by early spring (March) for best results, out of sightlines from the passionflower patch. They don’t like predators being able to follow them home, and appreciate a little cover or protection from marauding wasps. Catch up on the whole carpenter bee house saga here. There isn’t much love or interest for this amazing bee out there in the sciences or the general public, but I don’t understand why, now that I’ve taken the plunge (more on their progress at the end of the post). I’ve been planning a better designed carpenter bee house based on this year’s observations. I’ll share my bee house design before year’s end.

Planting for a Specific Pollinator

There are SO MANY native pollinators, from bees and wasps to flies and butterflies to moths and hummingbirds! If you have a favorite pollinator you want to support and enjoy, make sure to plant not only its favorite foods (its nectar source) but its larval host plants (caterpillar food). For example, the amazing hummingbird moth Hemaris thysbe lays its eggs on honeysuckle (Lonicera), snowberry (Symphoricarpos), hawthorns (Crataegus), cherries and plums (Prunus), and dogbane (Apocynum cannabinum). Once in flying moth form, it eats Lonicera, Symphoricarpos, Monarda fistulosa (which is where I saw it feeding up at Spikenard Honeybee Sanctuary), rose vervain (Verbena canadensis), and other pink and purple flowers. I’d recommend the native Lonicera sempirivens rather than Lonicera japonica, but have found articles recommending the latter for attracting this charismatic moth.

Another high profile example is our endangered monarch butterfly which needs Asclepias milkweed or butterfly weed and just a few other species to host the caterpillars and on which to spin their cocoons. Once the butterfly emerges, it forages on fall-blooming wildflowers, especially Solidago goldenrod, which used to bloom abundantly across North America and has now been virtually erradicated from those ditches and hedgerows. A Cornell study (here is the original paper) attributes part of the monarch’s decline to its best fall migration pathway along the coastlines blooming too few nectar flowers, particularly goldenrod. Goldenrod is widely believed to be responsible for hay fever, but actually is not as its pollen is too heavy to be airborn, according to all the articles I’ve read. So, to support monarch butterflies, be sure to plant masses of Asclepias (suited to your location) and masses of goldenrod and other native fall-blooming wildflowers. Scroll down for a number of resources by Xerces Society, NRCS and others on native flowers to plant to help both monarch butterflies and pollinators in general.

Natural Wildflower Combos

These combinations occur in nature, and look great together: Joe Pye weed and New York ironweed (and goldenrod), asters and goldenrod, which Robin Wall Kimmerer famously fell in love with (read her essay here). The sad thing is I don’t remember any other combinations and it’s not so easy to find them online. As we clear and spray our wild plant communities, a kind of knowledge dies. If you grew up seeing certain kinds of wildflowers always growing together, please comment below.

Getting It All Planted

When planting your pollinator plants, you have the choice to make a very intentional bed with edging and mulch and maybe signage, or if you have semi-wild areas, to just plant your plants in among the taller grass and weeds. Ian at Wood Thrush Natives gave me an idea for planting into a grassy area that we weed eat and mow by just choosing some more vigorous spreaders, punching holes in the grass, and allowing those plants to march out into the grass (that list and details below).

To get everything all planted, however you design your planting, you’ll want to plant in the spring or the fall when the weather is cool and rains are more likely. If you plant during the heat of summer, you can still do this if you can keep your plants watered until the weather cools off. Otherwise, water well when you first plant, and then after that first watering, you shouldn’t need to water your native plants! This is one of the benefits of planting natives. Some exceptions might include trees and shrubs during drought in the first year or two (you’ll have to watch to see if they’re struggling, getting brown leaves when they should be green, and so on). And perhaps if you’re planting an herbaceous perennial at the edge of its comfort zone during dry spells during the first year.

Remember that because your plants are native, they don’t need special compost, fertilizer, or other soil amendments if you’ve chosen the right plant for your setting. Granted, getting that perfectly dialed using online resources can be a bit of a chore when you’re new to these plants, but your native plant nursery or your native plant societies can help. You can also drive around your neighborhood and look at what’s growing wild. If your plants have a lot of potting medium, it’s probably best to knock off what you can and planting straight into the ground so that you don’t get an unhealthy water barrier between your plant and the surrounding soil. If your plants were potted in pine bark medium, you could even use it to mulch the top of the soil around your plant.

Plant in masses, drifts of flowers. Not only is this beautiful but it echoes the way these plants grow in nature in colonies. Some of these will spread on their own, others will need your help by planting multiples together to create these gorgeous masses.

Be Unique

Go wild and create a garden that’s unique to you! Variety is the spice of life and helps more pollinators. If we all plant the same three plants, we’re losing biodiversity and that doesn’t help anyone.

UPDATE!

Today, August 1, 2022, the day after I planted this Joe Pye weed, a monarch butterfly graced me!

Vigorous Pollinator Plants

Here are some wildflowers that can be planted straight into an established mowed area of deep grassy turf that will push their way out into the turf and assert themselves without much help from you (though you may want to carefully mow around them for the first year):

Joe Pye weed, goldenrods, boneset, swamp milkweed, spireae, blue mistflower, shrubs and trees.

Maintenance: Simply mow the herbaceous plants (not the shrubs and trees!) down in the very late fall, or, even better (because many of them provide winter food for all kinds of wildlife), let them stand all winter until very early spring (early March here in the mountains) and then mow them down. If you don’t like it looking so weedy, you can do a second mowing in early June and they will spring right back up and flower by the end of summer/early fall. You can carefully mow or weed eat between your plantings if your neighborhood association or your own aesthetics would frown on letting the grass grow up until your plants spread out enough to minimize or eliminate the grass. You could each year cut out a sod ring around your plants and remove grass to make it easier for your plants to spread and reduce the quantity of grass growing up.

Carpenter Bee Update

The featured image for this post was taken at Spikenard Honeybee Sanctuary in mid-July. These are Monarda fistulosa blossoms and Xylocopa virginica (carpenter bees) feeding on the bloom. The extra cool thing is that I’m pretty sure that the very large bee is the mother, and the little bee is the daughter! My own bees haven’t fared as well. I don’t think any of the larvae hatched! We don’t have much flower food around here, and I don’t know if that had anything to do with it, or if the bee house was more exposed to predator wasps who raided the chambers and made off with the babies. I assumed the bees had what they needed from the environment when I decided in May not to plant flower food for them, and was trying to avoid Michael’s fears of an infestation, but now I’m sad because they felt like pets! It’s really ironic, I know, given that we built the bee house as “pest deterrent.” Along the way, we removed the ‘s.’
