Cushion haworthia

Haworthia cooperi

Cushion haworthia is a tiny, choice, clump-forming succulent whose plump, soft, blue-green leaves end in translucent "windows" - in the wild the plant pulls itself down into the soil and lets light reach its inner tissues through these clear leaf tips, an adaptation to the bright, dry Karoo light. POWO (Kew) places it native to the Eastern Cape of South Africa (Cape Provinces). It is a jewel for a pot or a windowsill rather than a garden plant. Unusually for this group of succulents, it prefers BRIGHT INDIRECT light or part shade rather than harsh full sun, which scorches and reddens it; give it sharp drainage and water sparingly during growth, far less in winter. OVERWATERING - and cold, wet soil - is the main way it dies, and it is FROST-TENDER (RHS rates it tender, H1c-H2), so almost everywhere it is grown as a houseplant or in a frost-free greenhouse. It is grown for its jewel-like translucent foliage, not as a food plant, and it rarely flowers in cultivation.

Habit

A tiny, clump-forming succulent perennial forming a low rosette of plump, soft, blue-green leaves whose tips end in translucent "windows" that let light into the leaf - a jewel for a pot or windowsill rather than the open garden. It is a small, drought-tolerant succulent that, unlike most of this group, prefers BRIGHT INDIRECT light or part shade rather than harsh full sun, which scorches and reddens it. Give it sharp drainage and water sparingly during growth, and far less in winter: OVERWATERING and cold, wet soil are the main killers, causing the soft leaves to rot at the base. It is FROST-TENDER (about RHS H1c-H2), so almost everywhere it is grown as a houseplant or in a frost-free greenhouse. It offsets slowly into a cushion-like clump and is grown for its translucent foliage rather than its bloom, which it seldom produces in cultivation; it is inedible.

Care tips

•

Give it BRIGHT INDIRECT light or part shade, never harsh full sun - an east-facing sill or just back from a bright window; direct scorching sun reddens the leaves and clouds their translucent windows.

•

Water sparingly and only when the mix has dried out, and far less in winter; OVERWATERING and cold, wet soil are the most common way this soft-leaved succulent rots and dies.

•

Pot it in a very free-draining, gritty succulent or cactus mix in a small pot with drainage holes, ideally terracotta, and never leave it standing in water - sharp drainage is essential.

Lifecycle

Planting

Pot it in a very free-draining, gritty succulent mix (a cactus-and-succulent blend cut with extra perlite or coarse sand) in a small pot with drainage holes, ideally terracotta so the rootball dries fast. Set it in BRIGHT INDIRECT light or part shade - an east-facing sill or just back from a bright window - never in harsh, scorching sun.

Transplanting

Repot only every two to three years, or when offsets crowd the pot, moving up just one size into fresh sharply drained mix; too large a pot stays wet and rots the roots. Let the soil dry first, handle the soft leaves gently, and wait several days before watering so any disturbed roots can callus rather than rot.

Early growth

A young plant grows very slowly. Keep it in bright indirect light and let the mix dry out between sparing waterings - soft, stretched, or reddened leaves signal too little light, too much water, or harsh sun. It is far more forgiving of dryness than of soggy soil.

Maturity

As a houseplant it stays a small, slow-growing cushion of window-leaved rosettes, offsetting into a clump that can be divided. It rarely flowers in cultivation; given bright indirect light, sharp drainage, and very sparing water, it asks for little beyond an occasional repot and the removal of crowded offsets.

Propagation

Easiest from offsets: lift the small rosettes that form around the parent, let any cut surface callus for a few days, then pot them up in sharply drained mix and water sparingly until rooted. It can also be grown from seed or leaf cuttings, but division of offsets is quicker and keeps the plant true.

Tricyrtis hirta

Toad Lily

Tricyrtis hirta is a hardy herbaceous perennial native to the shaded rocky cliffs and stream banks of central and southern Japan (Wikipedia), prized for its orchid-like, white-to-pale-purple flowers speckled with dark purple spots that bloom in late summer and autumn when little else flowers. It fills a genuine gap in the shade garden calendar, bringing unusual beauty to north-facing borders and woodland edges. The honest catch is twofold: it demands consistently moist, humus-rich soil and absolutely detests drought or waterlogging, and its late-emerging, hairy stems are magnets for slugs in spring - a lapse in mollusc control can shred a clump before it even flowers.

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.

Hakonechloa macra

Japanese forest grass

Hakonechloa macra is a slow-growing, clump-forming deciduous grass endemic to Japan, naturally found on rocky woodland slopes near Mount Hakone and across Honshu. It is prized in shaded gardens for its gracefully cascading, fountain-like mounds of thin, arching leaves and warm autumn tones of red and pink. The honest catch is pace and site sensitivity: it is among the slowest ornamental grasses to establish, struggles badly in hot dry summers without consistent moisture, and is prone to leaf scorch if sited in too much sun - it needs rich, reliably moist soil to earn its reputation.

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.

Open pink and white Hippeastrum hybrid flowers showing trumpet-shaped blooms with prominent stamens in a garden setting

Hippeastrum x hybridum

Amaryllis

Hippeastrum x hybridum is a complex garden hybrid derived from six or more wild Hippeastrum species native to tropical and subtropical South America, developed through intensive breeding since the late 18th century and now the dominant "amaryllis" sold worldwide as a holiday bulb. It produces spectacular trumpet-shaped flowers - 5 to 8 inches across - on stout leafless scapes in red, pink, white, orange, salmon, or bicolour, making it one of the most dramatic winter-flowering houseplants available. The honest catch is toxicity: the entire plant, especially the bulb, contains lycorine and related alkaloids at concentrations that cause vomiting, salivation, tremors, and hypotension in pets and children, so it must be placed out of reach and handled with care.

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.

Gasteria bicolor is a slow-growing, tongue-leaved succulent native to the Eastern Cape of South Africa, where it grows on rocky slopes and outcrops in thicket vegetation around Port Elizabeth (a summer-rainfall region). Its mottled, strap-shaped leaves and arching racemes of curved, stomach-shaped pink-to-orange flowers make it a forgiving container plant for warm, frost-free settings, and it tolerates light shade better than most succulents - a useful trait for brighter indoor positions. The honest catch is its tenderness: it is damaged below about 41°F and cannot survive frost, so gardeners outside USDA zones 9b-11 must overwinter it indoors. It is a container-and-houseplant plant, not a garden perennial in most of the world.

Tiger aloe (Gonialoe variegata, syn. Aloe variegata) is a compact, evergreen succulent native to the arid Karoo region of South Africa and Namibia, where it grows in semi-shaded rock crevices with sharp-draining sandy or gravelly soil. In gardens it excels as a bold container specimen or focal-point succulent, prized for its spirally arranged dark-green leaves banded with irregular white spots and its tall orange flower spikes that sunbirds mob in the wild. The honest catch is frost-tenderness: this plant cannot survive temperatures below 41°F and must be overwintered under glass in all but the warmest frost-free climates - and every part of the plant is toxic to cats, dogs, and livestock via anthraquinone glycosides in the latex layer.

Haworthiopsis fasciata

Zebra haworthia

Zebra haworthia (trade name Haworthia fasciata; now correctly Haworthiopsis fasciata) is a tiny, rosette-forming succulent endemic to the Eastern Cape of South Africa, where it grows in acidic fynbos sands near Port Elizabeth and Uitenhage - listed Near Threatened on the SANBI Red List. It is one of the most widely sold succulents in the world: compact, slow-growing, forgiving of low water, and ASPCA-listed non-toxic to pets. The honest catch is twofold: it is frost-tender (barely tolerates a degree or two of frost, USDA zones 9b-11 outdoors), so almost everywhere it is a houseplant or temporary patio pot; and true H. fasciata is genuinely rare in cultivation - most plants sold under this name (and most images, including ours) are actually the closely related H. attenuata, which carries white tubercles on BOTH leaf surfaces rather than the smooth inner surface of the true species.
