spineless species has a thick stem to 5 ft (1.5 m) high, crowned by
a compact rosette of broad, soft-textured pale green leaves. Its
arched flower spike grows to 10 ft (3 m) in length and bears densely
packed greenish-white flowers which open over several months in
spring and summer. Lateral rosettes brancth off the main stem
making, in time, a large mound of rosettes. The cultivar Nerva has
bluish green leaves.
Cultivation: Plant in a well-drained, gritty soil in full sun. Water
regularly in summer. Frost hardiness varies from species to species,
but all are adapted to surviving very dry periods.
Propagate from offsets or from seed in spring or summer.
