Living stones
Lithops pseudotruncatella
One of the "living stones": a near-stemless dwarf succulent that looks exactly like the pebbles it grows among. Each plant is a single pair of fused, swollen leaves, almost flush with the ground, coloured and patterned to mimic the surrounding stones — a marvel of camouflage. Once a year, in autumn, the pair splits to push out a single yellow daisy-like flower, and in spring a new leaf pair forms inside the old one, which shrivels and is reabsorbed. POWO (Kew) places Lithops pseudotruncatella native to the stony semi-deserts of Namibia. It is FROST-TENDER and the single quickest way to kill it is OVERWATERING: it stores its own water and must be kept almost completely dry for much of the year, watered only lightly during active growth — and NOT at all while the old leaves are being reabsorbed in spring. RHS rates Lithops tender (H1c-H2); in any cold-winter climate it is grown as a pot plant on a bright windowsill or in a frost-free greenhouse, in full sun and an extremely gritty, sharply drained mix.

Tulipa (hybrid)
Tulip
The classic spring bulb of mixed borders and cutting gardens — a fall-planted perennial bulb whose single upright stem carries a showy cup-, bowl-, or goblet-shaped flower in nearly every color but true blue. Hybrid garden tulips bloom in April and May above a few strap-shaped basal leaves, then go dormant by early summer. They thrive on cool, moist winters and warm, dry summers; most hybrids bloom best the first spring and decline in later years, so many gardeners treat them as annuals.

Hyacinthus orientalis
Common hyacinth
A spring-flowering bulb grown for dense upright spikes of waxy, star-shaped florets in blue, purple, pink, red, or white — famous for an intense, sometimes overpowering fragrance. Plant bulbs in mid-fall for an April bloom; flower quality typically declines after the first year, so the densest spikes often need replanting every couple of seasons. Every part of the bulb is mildly toxic and the sap can cause contact dermatitis, so gloves are advised when planting.

Dionaea muscipula
Venus flytrap
The famous carnivorous bog plant — a low clumping rosette of hinged, jaw-like snap-traps fringed with stiff "teeth" that close on insects that touch their trigger hairs. Despite its worldwide fame and houseplant ubiquity, Dionaea muscipula is native to a single tiny region: the wet, fire-maintained pine savannas and bogs within roughly a 75-mile radius of Wilmington, North Carolina (and adjacent South Carolina). It is globally rare in the wild and poaching of wild plants is a serious, criminalized conservation problem, so buy only nursery-propagated stock. It is also far more demanding than its reputation suggests: it needs nutrient-poor acidic peat-and-sand soil, mineral-free water, full sun, and a genuine cool winter dormancy — and it declines and dies if treated as an ordinary warm year-round houseplant.

Hylotelephium 'Herbstfreude'
Autumn-joy stonecrop
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.

Lachenalia aloides
Cape cowslip
A small, choice, winter-growing Cape bulb (Lachenalia aloides) that throws up a pair of fleshy, often maroon-spotted strap leaves and a slender stem of pendent, tubular flowers shading from yellow through orange and green to red — a living jewel for a pot or a frost-free rockery. Native to the Cape Provinces of South Africa — the winter-rainfall Western Cape of the Cape Floristic Region (POWO, Kew) — it follows the rhythm of that Mediterranean climate: it is winter-growing and summer-dormant, the opposite of most bulbs, so it is watered from autumn through spring while it is in leaf and flower and then kept dry and at rest through summer. It is frost-tender (RHS H2): outside warm, frost-free climates grow it in a pot in a cool greenhouse or a bright, frost-free room, or in a sheltered, sharply drained spot. In its native fynbos the nodding tubular flowers are pollinated by sunbirds, with bees also visiting. The bulbs are toxic if eaten — it is grown strictly as an ornamental.

Agapanthus praecox
African lily
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).
