A bold, clump-forming evergreen perennial from South Africa, grown for big rounded umbels of trumpet-shaped blue (or white) flowers held on tall bare stalks above arching, strap-shaped leaves in mid-to-late summer. It is widely sold as "lily of the Nile," but that is a misnomer — the plant is South African (the Cape provinces and KwaZulu-Natal), not from the Nile. Spectacular and easy in warm climates, this evergreen Agapanthus is frost-tender, so in cold-winter areas it is grown in a container and overwintered under cover. The RHS has given several Agapanthus praecox forms its Award of Garden Merit and rates this evergreen species half-hardy (H3 — needs winter protection).

A clump-forming herbaceous perennial grown for its showy late-season flower heads: masses of tiny star-like flowers borne in flattened cymes 3-6 inches across that emerge rosy pink, deepen to rose-red, and fade to coppery-rust as they die. Gray-green, fleshy, succulent-like leaves form upright clumps to about 2 feet. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant and attracts butterflies, and its foliage and dead inflorescences persist into winter for added interest.

A tuberous-rooted member of the aster family native to Mexico and Central America, grown for showy summer-to-fall blooms in nearly every color except blue. Hybrids in commerce span ten flower-form groups (single, anemone, collarette, waterlily, decorative, fall, pompon, cactus, semi-cactus, and miscellaneous) and range from 1 to 6 feet tall. Winter-hardy only to USDA Zones 7-10; in colder regions the tubers are lifted in fall and stored frost-free, so most North American gardeners grow it as a summer annual.

Eucomis comosa, the pineapple lily or wine eucomis, is a deciduous summer-growing bulb in the asparagus family (Asparagaceae), endemic to the Eastern Cape and KwaZulu-Natal provinces of South Africa. From a large, often purple bulb it sends up a basal rosette of strap-shaped leaves and a stout flower spike packed with white-to-purple star flowers, crowned by a tuft of leafy bracts that gives it a pineapple-like silhouette in mid-to-late summer. It is a striking focal-point and container subject for borders, prized for its long-lasting bloom. Hardiness is the load-bearing caution: it is frost-tender to only borderline-hardy (RHS H4, roughly USDA 8–10, surviving brief dips near -5 to -10 C in well-drained, sheltered ground), so in colder climates it is grown in pots and lifted or moved under cover for winter, and it resents winter wet. The bulb and foliage contain saponins and can cause mild mouth irritation, drooling, and stomach upset if eaten, so keep it away from pets and children.

The classic white-and-yellow garden daisy — a clump-forming herbaceous perennial bearing showy single flower heads of white ray florets around a yellow central disc from midsummer into fall. A garden hybrid bred by Luther Burbank in the 1890s near snow-covered Mt. Shasta in northern California, it grows 2-3 feet tall and is a mainstay of the perennial border, cottage garden, and cutting garden. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant, attracts butterflies, and is resistant to deer and rabbit browsing.

Dierama pulcherrimum, angel's fishing rod, is an arching, more-or-less evergreen cormous perennial in the iris family (Iridaceae), endemic to the open summer-rainfall grasslands of the Eastern Cape of South Africa. It forms grassy tufts of long, narrow leaves from which tall, wiry, arching flower stems rise to about 1.5 m (occasionally to 1.8 m), each hung with pendulous, bell-shaped rosy-pink to purple flowers in summer — the namesake "fishing rod" silhouette over a pond or in a gravel garden. It is the load-bearing caution to note that this is only a borderline-hardy plant: RHS rates it H4 (hardy to roughly -10 to -5 C / USDA ~8b-9), so in colder zones it needs a sheltered, sunny, sharply drained spot, a winter mulch, or container/glasshouse protection, and it resents disturbance once established. It is not recorded as toxic — though it is grown purely as an ornamental and is not a food plant, so treat it as inedible. It is well-behaved (Least Concern in the wild, no recorded weediness) and suits borders, pond margins, and containers in mild-temperate gardens.
