Propagation
Sow fresh seed during spring and maintain a temperature of 18º to 21º C. (64º to 75º F).
Divide offsets when available during spring and place them in a well drained media and allow to the soil to drain away after watering. Plant out when large enough to handle.

Botanic information
Leaf: The fleshy textured leathery bluish-gray green ovate to broad lanceolate leaves are up to 80mm (3⅛ in) wide with an acuminate apex with a pungent spine. The undulate to crenate margins are armed with prickly brown down-curved spines, 15mm (⅔ in) apart and the leaves arch outwards from a compact rosette.

Flower: The small bright yellow cyathiform flowers have 5-tepals and strongly exserted greenish stamens. The pedicle is short and the flowers are arranged in a large rounded branched cluster. The clusters appear in a panicle above the foliage on a thick purplish scape that is up to 2.3 to 3.5m (11 ft) tall from early to late summer. This plant is monocarpic (dies after flowering).

Fruit: The oblong slightly dehiscent leathery capsule is up to 17mm (⅝ in) wide with a rounded apex and contains obovate winged seeds that are 5-7mm (¼ in) long by 4-5mm (⅛ in ) wide. The small dark seeds are viable but the plant is commonly propagated vegetatively.
