Catawba rhododendron

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 to 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 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.

A dense, conical-to-narrow-pyramidal evergreen tree native to eastern and central North America, prized as a screening and foundation conifer. Flat, fan-like sprays of scale-like, aromatic yellow-green foliage clothe the tree from the ground up, and red-brown bark exfoliates on mature trunks. Wild trees can reach 40 to 60 feet but cultivated plants typically stay near 20 to 30 feet; small urn-shaped cones and dense evergreen cover make it valuable food and shelter for birds.

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 to 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.

Loropetalum chinense is an evergreen shrub native to woodlands and thickets across southern China, Japan, Taiwan, and adjacent parts of Southeast Asia, valued in gardens for its distinctive ribbon-like flowers and, in the popular purple-leaved forms, year-round burgundy foliage. It thrives in zones 7-9 as a bold structural shrub or hedging plant, blooming most heavily in late winter to early spring. The honest catch is its absolute dependence on acidic soil: even slightly alkaline pH triggers iron chlorosis, and in the Southeastern US a bacterial crown gall disease can cause rapid branch dieback and plant death, making site preparation and soil testing non-negotiable before planting.

The classic broadleaf-evergreen shrub of formal hedges, topiary, and clipped borders - small, glossy dark-green opposite leaves on a dense rounded frame that takes shearing better than almost any other shrub. Native to southern Europe, western Asia, and northern Africa, it carries inconspicuous greenish-cream spring flowers and holds its leaves year-round. All parts are toxic if eaten and the foliage can cause skin irritation, but that same chemistry makes it reliably rabbit- and deer-resistant.
