A virtually stemless, broadleaf-evergreen native of central and eastern North America: a basal rosette of rigid, sword-shaped, spine-tipped leaves up to 30 inches long, fringed along the margins with the curly white threads that give the species its name. In early summer a flowering stalk shoots from the center to 5-8 feet, carrying nodding, bell-shaped, creamy-white flowers. Tough enough for poor sandy soil, heat, drought, and salt spray, it earns its keep as architectural structure in dry and seaside gardens.

A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.

A woody, deciduous flowering shrub in the Hydrangeaceae, native to Japan, China, Korea, and Southeast Asia and long grown as the classic "hortensia" or French hydrangea. NC State Extension describes a rounded shrub 3 to 6 feet tall and wide with large opposite, simple, toothed leaves (4-8 inches long) and big rounded mop-head or flat lacecap flower clusters in late spring and summer in white, pink, blue, or purple. Famously, flower color tracks soil chemistry — acidic soils push the blooms blue and alkaline soils turn them pink. It wants protection from hot afternoon sun and steady moisture, making it a mainstay of shaded foundation plantings and woodland borders.

A deciduous shrub grown almost entirely for its explosion of yellow four-lobed flowers that line the bare arching stems in early spring, before the leaves emerge. A garden hybrid of two Asian species (Forsythia suspensa × F. viridissima) — not native to North America. Missouri Botanical Garden describes it as a "one-season wonder" that fades into the background after bloom, so it earns its place as a late-winter color signal rather than a four-season anchor.

A broadleaf evergreen shrub from Japan, China, and Korea, grown for showy 3-5 inch winter-to-spring flowers in white, pink, red, yellow, and lavender against glossy, leathery, dark green leaves. The most widely cultivated camellia, with thousands of named varieties and a single straight-species form whose broad overlapping petals surround a dense boss of golden-yellow stamens. Winter hardy only to USDA zones 7-9, it needs moist, acidic, organically rich soil and the shelter of part shade.

A large, rounded, multi-stemmed broadleaf evergreen shrub of the southern Appalachians — typically 6-10 feet tall (rarely to 20) with glossy dark green leaves and showy compact terminal trusses of 15-20 funnel-shaped lavender-pink flowers in mid to late spring. Native from Virginia to Kentucky south to Georgia and Alabama, where it forms dense thickets on rocky high-elevation slopes and ridges. Prefers cool summers, acidic moist-but-well-drained soil, and part shade; all parts are highly toxic if ingested.
