Height: 15–18in (38–45cm)

Spread: 10in (25cm)

Winter: See below

Summer: See below

Care: Pot small bulbs in 3in (7.5cm) pots; larger bulbs, up to 3in (7.5cm) wide, in 5in (13cm)-wide pots. Pot in early autumn (although spring is also possible); leave the top of each bulb protruding ½–¾in (12–18mm) above the compost, lightly water, and place in 37–41°F (3–5°C). Initially, place in light shade; as growth begins, gradually increase the amount of light to direct light but not full sun. In spring, slowly increase temperature to 50°F (10°C), water more freely, and place in direct light without full sun. In summer, place on a warm, sunny windowsill and keep compost moist.

Propagation: Remove offsets in autumn or spring and pot into small pots. Offsets take up to 3 years to reach flowering size, until which time place in a greenhouse that is frost-free in winter and gently warm in summer.
