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 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 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.

A dense, upright-to-rounded broadleaf evergreen shrub, 8-10 feet tall and 6-8 feet wide, grown for year-round structure and its long late-winter-to-spring show of drooping panicles of fragrant, urn-shaped white (sometimes pink) flowers. Glossy dark green leaves are joined each spring by a striking flush of bronze-red to coppery new growth, and the chains of greenish-red flower buds form in fall and hold all winter for a second season of interest. Native to southeastern China, central to southern Japan, and Taiwan, it wants acidic, evenly moist but well-drained soil, shelter from harsh winter wind, and protection from hot afternoon sun in warmer zones. All parts are toxic if eaten.

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 4-8 feet tall and 4-10 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.
