An airy, see-through ornamental in the vervain family (Verbenaceae), native to South America and naturalized across the warm southeastern United States. NC State Extension describes an erect plant 2-5 feet tall on thin but strong red-marked green stems, topped from summer into fall by dense, flat-topped clusters of small tubular purple-lavender flowers held well above mostly basal, lance-shaped, serrated dark-green leaves. A perennial in USDA zones 7-11 (grown as an annual in colder climates), it is fast-growing, drought and deer tolerant, and a magnet for bees, butterflies, and hummingbirds — though it self-sows freely and some sources have labeled it invasive.

Cherry laurel is a fast-growing evergreen shrub or small tree native to the Black Sea rim — from Albania and Bulgaria east through Turkey to the Caucasus and northern Iran — prized for its bold, glossy foliage, spring racemes of creamy-white flowers, and unmatched tolerance of shade, drought, and heavy pruning. It makes an outstanding dense hedge, screen, or woodland understory filler in zones 6–9. The honest catch is a two-part warning: every part of the plant contains cyanogenic glycosides (prussic acid), making leaves, seeds, and fruit genuinely toxic to humans and animals; and in mild, moist climates such as the UK and Pacific Northwest it seeds aggressively via bird-dispersed fruit, is classified as invasive, and can smother native understory vegetation wholesale.

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.

Snowberry is a deciduous, suckering North American shrub native across Canada and the northern and western United States, prized for its waxy, snow-white berries that persist well into winter after the leaves have dropped. It tolerates a wide range of soils and exposures — full sun to deep shade, chalk to clay — making it one of the most adaptable shrubs in the genus. The honest catch is threefold: the berries are toxic to humans (causing vomiting), the rhizomatous root system can colonise an area to form dense, hard-to-remove thickets, and the plant spreads aggressively in moist soils — so it is a plant that earns its place in naturalistic or wildlife plantings but demands a firm boundary in a tidy garden.

A tall, sun-loving, drought-tolerant perennial in the daisy family, grown for its broad, flat-topped corymbs of tiny golden-yellow flowers held on stiff stems above finely divided, aromatic gray-green ferny foliage. Native to the Caucasus, Iran, and Afghanistan and long naturalized in gardens worldwide, it forms a tidy upright clump (rather than running like common yarrow) and is one of the most reliable, low-care pollinator and cut-flower plants for hot, dry, full-sun borders.

A dry-country wildflower of the Intermountain West whose narrow, scarlet, tubular flowers line a slender stalk that rises about 3 feet above a low rosette of glaucous blue-green leaves. The Lady Bird Johnson Wildflower Center documents it blooming red from May into August on dry, gravelly soils, and it is one of the classic hummingbird-pollinated penstemons. Deeply drought-tolerant once established — best on lean, well-drained ground where it is not over-watered.
