I’m often asked: “I want to go native but what should I plant?” I like to start with shrubs and small trees – they provide structure, plus year-round habitat and interest, while maturing faster than full-sized trees. The local list is amazingly long, thus the length of this post (don’t blame me – blame the number of plants).
Featured here are shrubs and small trees that I have actually seen growing in uncultivated areas in Stamford, CT, under circumstances that lead to a reasonable conclusion that the plant is a local genotype rather than, say, a garden escapee or something planted in the wilds in a well-meaning (but often misguided) restoration attempt.
There are a whole lot more shrubs which are said to include Connecticut within their “range” (see list at the end of this post). The reason that I haven’t seen these other plants could be because the deer ate them all or it could be that the plants don’t naturally occur in the warmer, coastal section where I live. A third possibility is that they don’t naturally occur in CT at all and ended up on various lists by mistake.
So here’s the laundry list with some rough notes. This list is intended as a starting point - a list of resources for further research appears at the end of the post. The full description of these beauties, their value to wildlife, and their cultural conditions is, of course, a book.
As a general rule, if you want to plant native, stick to the species plants, preferably local genotypes. Garden cultivars, particularly those that are resistant to this or that, and those that distort the plants’ natural characteristics, are unlike to function as native, in my view. Further, only the species plants from your area (not the other end of the state) are likely to be the acceptable host species for the specialized herbivores actually in your area, and if the plant is not supporting these animals, what use it is? (Yup, I’m a purist!)
Native Shrubs and Small Trees for Southern New England
1. Speckled alder (Alnus rugosa) – nice shrub turns into a graceful small to mid-sized tree- handsome catkins bloom in March, attractive foliage. Does wet and garden.
2. Shadblow/shad/serviceberry (Amelanchier canadensis) – graceful, small apple-relative, works well in part shade in urban settings and adorns the edges of the local woods. Apple-like early spring flowers (when the shad run up the Hudson). June fruit disappears fast. Trunk bark has an attractive pin-stripe. Plant away from junipers to limit the spread of cedar-apple rust fungus (not harmful but can be messy in an extreme case).
3.- 4. Paper and gray birches (Betula papyrifera, B. populifolia) – decorative, small, white-barked trees, with early season flowering catkins. Good small yard trees. Mix well with evergreens for winter interest. Good bugs. Easy from seed.
5.- 6. Hornbeam/ ironwood (Carpinus caroliniana) – graceful small trees for understory conditions. Rough-barked hop hornbeam (Ostrya virginiana) is a close relative and good too. Both have early catkins as is typical of the Betula (birch) family; both also have unusual, decorative seed coverings.
7. Buttonbush (Cephalanthus occidentalis) – outstanding large, thick bush for a wetter area. Very tough. Easy to start from seed. Beautiful mid-green leaves, pretty flowers, etc. Beloved of swallowtail butterfly larvae and many other insects and pollinators. One of my favorites.
8. Sweet pepperbush (Clethra alnifolia) – Summer blooming – like pearls, good anywhere, any time. Best flowering with a bit of sun plus average garden or wetlands moisture. Kids will love this: at least in wetlands, the flowers often harbor ambush bugs. Butterfly favorite.
9. Sweet fern (Comptonia peregrina) — does ordinary garden to hot/dry; badly underused, nice compact, fine-textured bush with good color. This plant is off by itself in the wax-myrtle family with no siblings to speak of; it’s vaguely related to beeches.
10. Silky dogwood (Cornus amomum) – is the only local shrub dogwood. Twigs turn a beautiful red in winter. The late summer fruit is very important to local wildlife – you can decorate your garden with fruit-loving birds. Silky dogwood does wetland and garden conditions. Best fruit in full sun with ample moisture.
11. Flowering dogwood (Cornus florida) – nice small tree for part shade with good air circulation; stunning in the understory. If possible, give it morning, rather than afternoon or mid-day, sun. Seems to have survived the invasive anthracnose that was plaguing it a few years ago. Good late season fruit. America’s answer to the flowering Japanese cherry.
12. American hazelnut/American filbert (Corylus americana) – Grows in the wetter sections of the woods often near a wetland. Can be confused with witchhazel but look for the serrated leaf edges and the early-season catkins of this multi-stemmed birch relative. The hazelnuts that I know in the wild only produce a few fruit each year but they are encased in lovely, frilly, leafy skirts of lime and pink – you have to see this to believe it.
13. American witchhazel (Hamamelis virginiana) – be careful to get the local species that blooms in the fall; attractive small tree for the understory with large, flat leaves to add visual texture. Nice twigs too. Important for late-season pollinators. Does open woods to riparian buffer.
14. American holly (Ilex opaca) – grows to be a medium-sized tree. You need male and female for fruit. Often seen in the older parts of town in pairs gracing either side of the front door. This is good placement but plant far enough away from the house for air circulation and to take into account the tree’s mature size. Nice, thick winter shelter. I love coming across a baby one, bird-spread, struggling to grow in an odd part of the woods.
15. Winterberry (Ilex verticillata) – always good in the garden, great winter fruit. It can be hard to get species plants, let alone local genotypes (Earth Tones Native Plant Nursery has them); the birds don’t seem to accept all garden cultivars – nor would we wish to spread them. For all hollies, you need male and female plants for fruit.
16. Eastern red cedar (Juniperus virginiana) – There is some question as to whether this pioneering juniper is fully native to CT or arrived too late after the last Ice Age to be an evolved, in-balance member of the ecosystem but it’s good winter survival food and good winter shelter.
17. Mountain laurel (Kalmia latifolia) – it’s wonderful! Likes the understory, with well drained, acidy soil. Show-stopping late spring flowers, beautiful branching shape, well-behaved. What more could you want?
18. Spicebush (Lindera benzoin)- fantastic understory shrub; naturally does edge-of-wetlands. Not too tall. Open form; tiny spring flowers; mid-season, brilliant red fruit with a nutritious high-oil content. Has its own swallowtail butterfly. Relative of sassafras; is a true spice.
19. Sweet crabapple (Malus coronaria) – is said to be native to the NY border and naturalizes well in CT. provides important winter fruit and gorgeous spring flowers. My personal all-time favorite. Crab apple cultivators seem to naturalize OK.
20. Northern Bayberry (Myrica pensylvanica) – thrives by the mailbox where you get road salt. Birds love the berries. Semi-evergreen. Said to need full sun and to tip-layer easily.
21. -22. Beach plum (Prunus maritima) – great if you live along the Long Island Sound and can plant in a sandy dune just above the high tide line. Good for the same area is northern marsh elder (lva frutescens).
23. Hop tree (Ptelea trifoliata)– underused native, called a tree but more of a multi-stemmed bush. Pretty compound leaves, large, decorative seeds. Like many of the other shrubs and small trees listed here, hop tree has been included in the plantings at the High Line in NYC.
24. Pinxterbloom azalea (Rhododendron periclymenoides) – deciduous azalea with showy flowers, understory in open woods; always a treat when I come across this in the wilds; gets deer-browsed.
25. Swamp honeysuckle (Rhododendron viscosum) – another nice one for the wetlands; trumpet- shaped flowers, attractive winter buds.
26. -29. Staghorn (Rhus typhina), smooth (Rhus glabra), fragrant (Rhus aromatic), and shinning sumac (Rhus copallina) – are all good, especially in large stands near the edge of a building or a woodlot. Use a root barrier to prevent unwanted spreading. Good winter bird food. Awesome color all year.
30-31. Caneberries (Rubus, spp.)- we have several local red raspberries e.g. American red raspberry (Rubus idaeus) and blackberries e.g. black cap raspberry (Rubus occidentalis) that are good for large areas where they can ramble. The only invasive caneberry of note at this time is wineberry (with red-haired stems). The natives are easy to start from cuttings or tip layering. The invasives Rosa mulitflora, Rosa rugosa and wineberry are easily replaced with local caneberries and native roses– they grow in the same place, so often if you keep cutting the invasives back, the natives will often fill in the space via the birds.
32. Elderberry (Sambucus canadensis) – wonderful; starts easily from a cutting rooted in water. Berries are high in antioxidants for the birds. Can get 10-12 feet high. Does ordinary garden in part shade or full sun with ample water. Hollow steams were historically used for everything from flutes to drinking straws and needle cases. Stems break easily so should be protected from, say, pick-up football games. Called “nature’s medicine chest”.
33.White Meadowsweet (Spiraea alba) – nice for wet or part shade woodland understory; summer blooming; open growth so might not be a front-of-garden show piece. Seems to be spreading locally so I guess the whitetail deer don’t care that much for it but, then, you never know with deer.
34-36. Swamp rose (Rosa palustris) – wonderful for the wetter areas; the Scalzi Riverwalk Nature Preserve’s test at a local nursery school is showing that it also thrives under ordinary garden conditions. Large single rose flowers in a bright pink, followed by large brilliant red hips. In swamps, grows to at least 10 feet. Virginia rose (Rosa virginiana) and pasture rose (Rosa carolina) are good for drier areas. Lay off the chemicals and enjoy the leaf spots as part of the plants’ natural beauty. Grows easily from seed.
37.-38. Pussy willow (Salix discolor) and Bebb’s willow (S. bebbiana ) do ordinary garden as well as wet areas, pussy willow becomes a tree; Bebbs stays shrub-sized. Wonderful for riparian areas. Robins are partial to the nesting crotches of larger pussy willows. Supports extremely interesting bugs.
39. American Bladdernut (Staphylea trifolia) – very pretty, well-behaved but under-used shrub, interesting late summer seed cases. Does a fair amount of dry-ish shade.
40. – 41. Eastern hemlock (Tsuga canadensis) and arborvitae (Thuja occidentalis) – are actually large trees but can be grown as shrubs to help you amass enough native conifers for adequate winter cover for your foundations and your birds. Hemlock is plagued by invasive wooly adelgids if planted under less than ideal conditions (understory woodlands – part sun, acid, moist but well-drained soil).
42 – 43. Blueberry (Vaccinium angustifolium , V. corymbosum) - stunning fall color – better than invasive winged euonymus could ever be. Need two plants that bloom at the same time for fruit. Low bush is better than high bush for shadier areas. Shallow roots need acidy leaf-mold mulch and adequate moisture but don’t do wetlands except for our local swamp blueberry sub-species. Blueberry cultivars seen to be OK for the garden (but not for introduction in uncultivated areas) as long as you’re not planting them where they could interbreed with and corrupt native stock. Blueberries are wimps so protect them from aggressive garden plants. Your yard robins will be delighted by this food from their familiar woodlands.
44.- 46. Arrowwood viburnum (Viburnum dentatum) – very adaptable. Be very very careful when choosing viburnums as several non-natives have gone rogue. Arrowwood has delicate white flower clusters followed by fast-disappearing blue fruit. The leaves look pleated and the leaf edges look cut with pinking shears. Hobblebush (Viburnum lantanoides) doesn’t do coastal but is OK north of the Merritt Parkway, be careful to not confuse it with the invasive linden leaf viburnum. American Cranberry Bush (Viburnum trilobum) is good but often confused with the invasive European – even by the sellers. I have noticed in the woods that the viburnums which succumb to viburnum beetles are the ones in too much shade. At Scalzi Riverwalk Nature Preserve, we thin the canopy cover over the arrowwoods to discourage these invasive pests.
47. Maple-leaf Viburnum (Viburnum acerifolium) – best shrub there is for deep shade. Nice flowers and berries, good fall color. Can get 10 feet tall when the deer don’t over-browse it.
48. Opps: I forgot: Choke cherry (Rosaceae Prunus) 25’ white flowers, good fall color, leaves poisonous to livestock, lovely bark, summer red-black fruit important to birds but messy – plant away from paths, driveways and patios, OK in part shade.
49. And one more: Sassafras (Sassafras albidum) 40- 50’ Can occur as a tree or shrub; naturally likes edge-of-woods; not particularly drought tolerant. Suckers so best allowed to grow in clumps in an uncultivated areas. Great fruit for birds. Lovely fall color. Like mulberry, 3 leave shapes (snow shoes, mittens, and gloves) but unlike mulberry leaves are smooth edged, papery, and medium to large in size.
Native Woody Stemmed Ground Covers
GROUND COVERS: If you want to add the woody-stemmed ground covers, depending on your area, there’s bearberry, huckleberry, bog laurel, sheep laurel, bog rosemary, several dewberries, common juniper, leatherleaf, wintergreen, cranberry, Canada yew, bunchberry, trailing arbutus, sea lavender …..
NEVER NATIVE: Despite popular belief, the following are not native to CT: Virginia sweetspire (Itea virginica), Witch-alder (Fothergilla, sp), Eastern redbud (Cercis canadensis)
More Native Small Trees for Southern New England
MORE: The above 60+ plants ought to be enough, right? However, here’s 40+ more that are said to include Connecticut in their “range” (whatever that means — probably “area of actual distribution by any means” rather than “area where naturally occurs”). I’ve never seen these plants in the wild but have no experience with the north or east part of the state or any ground that’s not deer-ridden. I won’t consider them native for your area until you have proof that they actually grow in your local area or an adjacent area.
If you have a confirmed sighting of any of these plants occurring naturally in CT, please add at comment. I’d be particularly interested in Aronia which seems to pop up in so-called “native” gardens and restorations in my area on a regular basis.
