Snowberry

Two things to settle before anything else. First, the name: this catalog already carries a plant called Possumhaw, and it is a holly, Ilex decidua. They are unrelated, they want different ground, and only one of them is this shrub. Missouri Botanical Garden files this species under smooth witherod and mentions possumhaw viburnum second, which is the safer name to buy under. Second, the ground: this is the wet-soil viburnum. MBG rates it medium to wet water, lists wet soil as its one tolerance and rain garden among its two suggested uses, and the Lady Bird Johnson Wildflower Center puts it in savannas, low wet woods and bogs on wet, mucky, acid soils. That is the axis that separates it from its relatives here. Mapleleaf viburnum is the dry-shade suckering understorey shrub, nannyberry is the tall small tree of upland edges, and possumhaw viburnum is the one you plant where water sits. What you get for the wet feet is the best fruit display in the group and one of the best of any native shrub. The ovoid berries do not simply ripen, they run a colour sequence - light pink, then deep pink, then blue, then purplish black - and because a cluster ripens unevenly, deep pink and blue-purple berries commonly sit in the same cyme in late summer against glossy dark green leaves that follow with maroon to red-purple fall colour. The catch is that the display depends on pollination. MBG says outright to plant shrubs in groups rather than as single specimens for best cross-pollination and subsequent fruit display, so a lone plant is the one way to get all of the shrub and none of the reason for it.

Sasanqua camellia is an evergreen shrub native to the forests of southern Japan - Kyushu, Shikoku, and the Ryukyu Islands - where it grows on forest margins and hillsides. In gardens it is prized as the earliest-flowering camellia, bearing fragrant blooms from September through January when almost nothing else is in flower, and it tolerates more sun and drought than its cousin Camellia japonica. The honest catch is cold hardiness: open flowers are blackened by hard frost, and the plant itself is reliably hardy only from zone 7a south, making it unsuitable for much of the northeastern and midwestern United States without meaningful shelter.

Creeping cotoneaster is a deciduous spreading shrub native to the mountains of central and southwestern China, Nepal, and Taiwan, prized for its distinctive flat herringbone branching, tiny pink-white summer flowers, and masses of vivid red autumn berries that sustain birds through winter. It holds the RHS Award of Garden Merit and tolerates poor, dry soils on banks and walls where little else will perform. The honest catch is twofold: the berries are mildly toxic to humans and pets (cyanogenic seeds, GI-irritant flesh), and the plant self-seeds freely enough that it is naturalising widely in the UK and Ireland and is considered potentially invasive - a real concern before planting near wild margins or hedgerows.

Nannyberry is the viburnum you can walk under. Missouri Botanical Garden describes a large, upright, multi-stemmed, suckering shrub of 10 to 18 feet that may also be grown as a single-trunk tree reaching 30 feet, and that second option is most of the reason to choose it: in a group where almost everything tops out as a rounded 6-to-10-foot mass, this is the one that can be limbed up into a small tree with a canopy, a trunk and usable space beneath. It is also the northernmost of them. MBG rates it Zone 2 to 8, the native range runs from New Brunswick west to southeastern Saskatchewan, and Wikipedia calls it one of the best small trees of eastern America for parks and gardens in regions of extreme winter cold. The fruit is the second argument. Flat-topped white cymes up to 5 inches across open in May and give way to blue-black drupes on reddish stalks that hang into winter, and unlike most of the genus they are genuinely good to eat - thick-skinned, sweet and juicy in Wikipedia's description, eaten off the bush or made into jam per MBG. Two caveats belong up front. The first is mildew: MBG lists mildew and leaf spot as occasional problems and the Lady Bird Johnson Wildflower Center says outright that it sometimes develops mildew in shady areas, so this is a plant to give sun and moving air rather than a stuffy corner. The second is that it colonises by two routes at once. It sends up root suckers, which MBG says to remove unless naturalisation is what you want, and the Wildflower Center adds that old branches arch down and take root where they touch. Left alone at the back of a property that behaviour builds a thicket for free; in a tended border it is a job that returns every year.

A large, hairy, clump-forming North American native perennial of wet meadows, low woods, stream banks, and prairies. Its most distinctive feature is the perfoliate foliage - pairs of wrinkled, opposite, lance-shaped leaves whose bases fuse around the hairy stem, so the stem appears to pass through the leaf. From July to September, flat-topped clusters of small, fluffy white flowers feed a wide range of bees, butterflies, and other pollinators, while all parts of the plant are toxic and bitter.

A large, vigorous, fountain-shaped deciduous shrub that earns its common name in late spring, when its arching stems are smothered in masses of pale-pink, yellow-throated, bell-shaped flowers. Native to China, it is one of the great old-fashioned spring shrubs - spectacular in full bloom, much loved by bees, and offering peeling brown bark for quiet winter interest. It is also genuinely big: expect 6 to 10 feet tall and wide at maturity, so give it room rather than fighting its size with the shears. The form to seek out is the Award-winning "Pink Cloud", which carries a clearer, richer pink than the variable seed-grown species.
