About
Eucomis autumnalis, the autumn pineapple flower, or autumn pineapple lily, is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae, native to Malawi, Zimbabwe and southern Africa. It is a mid to late summer flowering deciduous bulbous perennial. The flower stem reaches about 40 cm (16 in), rising from a basal rosette of wavy-edged leaves. The green, yellow or white flowers are arranged in a spike (raceme), topped by a "head" of green leaflike bracts. It is grown as an ornamental garden plant and can also be used as a cut flower.
How to grow it
Eucomis autumnalis is grown as an ornamental plant. The flowers and later the fruiting stems remain decorative for many weeks, and can be used as cut flowers. E. autumnalis survives frosts down to about −7 °C (19 °F), particularly if planted in a sheltered position in well-drained soil, kept as dry as possible during the winter dormancy. It grows and flowers best planted in full sun or partial shade in a fertile soil, and kept well watered during the summer period of growth and flowering.
A cultivar is available under the name "E. autumnalis 'White Dwarf'". However, as of 2018, the RHS Plant Finder regards this as a cultivar of E. zambesiaca rather than E. autumnalis.
