Barberton daisy

Aloe maculata (soap aloe, also called zebra aloe; long sold as Aloe saponaria) is a clumping, stemless succulent from southern Africa with broad, triangular leaves marked by distinctive "H-shaped" pale spots. It is grown for its flat-topped racemes of tubular flowers in shades of orange-red to coral and yellow, held on tall branched stalks that draw sunbirds, bees, and other insects. A tough, drought- and salt-tolerant groundcover that spreads by suckers, it suits rock gardens, dry borders, coastal plantings, and containers in warm climates. It is frost-tender: the RHS rates it H1C (roughly USDA 9b-11), so leaves are damaged below freezing and it needs protection or indoor wintering where frosts occur. The leaf gel is used traditionally for skin and other ailments, but the plant is recorded as harmful if eaten (handle with care; seeds are reputedly poisonous), so treat it as not for casual consumption around people and pets.

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 23 to 14°F 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.

Veltheimia bracteata, the forest lily, is a winter-growing bulbous perennial from the forest margins and coastal scrub of South Africa's Eastern Cape, grown for its glossy rosette of wavy-edged strap leaves and a tall, dense raceme of pendent tubular flowers in shades of pink to rose, blooming in late winter through spring when little else is in flower. It is frost-tender (RHS H2): it tolerates cool conditions but not freezing, so outside roughly USDA zone 9b-11 it is grown as a container or conservatory bulb, dormant and dry through summer. It thrives in semi-shade with humus-rich, well-drained soil and makes an excellent pot specimen. The bird-pollinated flowers attract sunbirds. As a member of Asparagaceae (subfamily Scilloideae), it is grown for ornament only; the bulb is toxic and must not be eaten. It is well-behaved and not reported as invasive.

Coronilla valentina is a compact, evergreen Mediterranean shrub in the legume family (Fabaceae), with a native range spanning the Mediterranean Basin from Portugal and Spain through Italy, the NW Balkans and Greece to the Aegean and Turkey, and south across northwest Africa to Libya. In a warm, sheltered garden spot it rewards with prolific, intensely honey-scented yellow flowers from late winter into summer and handsome glaucous foliage year-round. The honest catch is cold-hardiness: RHS rates it H4 (hardy to about 14°F), so it is borderline at the cold edge of USDA zone 7 and is liable to be cut to the ground or killed outright in a hard freeze, demanding a sheltered south- or west-facing wall in colder gardens - and the whole plant is toxic to humans and livestock.

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 to 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 24 inches. 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.
