Oakleaf hydrangea

Hydrangea quercifolia
A four-season native shrub of the southeastern United States, where NC State Extension notes it grows wild in moist woods and along stream banks. It is an upright, multi-stemmed deciduous shrub, slow-growing to roughly 4 to 8 feet tall and 4 to 10 feet wide, named for its large, oak-shaped, lobed dark-green leaves. Showy pyramidal 4-12 inch panicles of creamy-white flowers open from late spring into summer and fade to pink and then tan, while the bold foliage turns wine, orange, and mahogany in fall over peeling cinnamon bark. Easy and low-maintenance in organically rich, well-drained soil, it is grown as a specimen, in masses, or as an informal hedge.

Blue false indigo (Baptisia australis) mature clump in a garden bed, showing the upright bushy mound of blue-green trifoliate foliage topped with violet-blue flower spikes.
Baptisia australis
Blue false indigo
A long-lived native perennial of central and eastern US woodland borders and prairie meadows with deep blue pea-shaped flowers in late spring, blue-green leguminous foliage, attractive black seed pods for winter interest, and a nitrogen-fixing root system (Fabaceae). Larval host for 6 documented butterfly species per NC State (orange sulphur, clouded sulphur, frosted elfin, eastern tailed-blue, hoary edge, wild indigo duskywing) - among the highest Lep-host-count perennials in the eastern flora.

Hardy hibiscus (Hibiscus moscheutos) in flower: a large saucer-shaped bloom with broad overlapping petals and a contrasting central eye around a prominent columnar staminal tube, above broad green leaves.
Hibiscus moscheutos
Hardy hibiscus
A bold, moisture-loving native perennial of eastern North America that dies back to a woody base each winter and returns to throw up stout 2 to 6 feet stems topped with enormous 4-8 inch saucer-shaped flowers - white, pink, red, or burgundy, each with a contrasting central eye - from June into September. NC State Extension describes a herbaceous perennial hardy across USDA zones 4a-9b that thrives in wet to constantly moist soils, tolerates heat, humidity, and even brief flooding, and draws hummingbirds, butterflies, and other pollinators. The tropical-looking dinner-plate blooms make it a dramatic focal point for rain gardens, pond edges, and the back of a sunny border.

Beauty bush (Kolkwitzia amabilis) - bell-shaped (campanulate) tubular flowers borne in dense clusters along the branch, pale-pink to white corollas with a bright yellow-orange throat marked by orange reticulate veining, abundant simultaneous bloom (flowering branch smothered in flowers) on a leafy deciduous shrub.
Kolkwitzia amabilis
Beauty bush
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.

Ribes sanguineum in bloom in Whatcom County, Washington, showing pendant clusters of deep-pink flowers on bare stems
Ribes sanguineum
Flowering Currant
Flowering currant is a deciduous shrub native to the Pacific coast of western North America, from British Columbia south through Washington and Oregon to coastal California (as far south as Santa Barbara County), with a marginal inland presence in Idaho and a southern outpost on Guadalupe Island, Mexico. Its bold dangling racemes of deep-pink to crimson flowers open in early spring, often before the leaves, making it one of the most conspicuous late-winter shrubs in mild gardens. The honest catch is threefold: it is a confirmed alternate host of white pine blister rust (a serious pathogen of five-needled pines), its blue-black berries are edible but notably insipid, and it has become an established invasive weed in New Zealand (where it forms dense stands excluding native species) and is a more minor, localized weed in Tasmania.

Guelder rose (Viburnum opulus) - heavy drooping cymes of glossy, translucent red berries hanging on bright red pedicels, maple-like deciduous leaves with 3-5 pointed lobes and toothed margins, shrubby branch habit with berry clusters set among the foliage.
Viburnum opulus
Guelder rose
A large deciduous European-native shrub grown for a three-season show: maple-like lobed leaves that color well in autumn, flat white lacecap flower clusters in late spring, and heavy drooping bunches of translucent red berries that hang on into winter. Each flower head is a showy ring of large sterile outer florets surrounding a fertile center, giving the lacecap its distinctive look. It is one of the best all-round wildlife shrubs you can plant - the open flowers feed hoverflies and bees, and the red fruit feeds birds through the cold months - and it tolerates wet soil, making it a natural choice for hedgerows, damp corners, and wild gardens. Two honest cautions go with it: the raw berries are mildly toxic to people, and this is the European guelder rose, not the North American cranberrybush.

Pink Camellia sasanqua flowers with glossy dark leaves at Nagai Botanical Garden, January 2026
Camellia sasanqua
Sasanqua camellia
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.
