About
Eucomis bicolor, the variegated pineapple lily is a bulbous species of flowering plant in the family Asparagaceae, subfamily Scilloideae, native to Southern Africa (the Cape Provinces, Lesotho, KwaZulu-Natal, the Free State, and the Northern Provinces). It is occasionally cultivated outside of the African continent as an ornamental bulbous plant.
How to grow it
In cultivation, Eucomis bicolor may not be fully frost-hardy. In the US, it is classed as hardy in USDA zones 8–10, and usually requiring a winter mulch in colder areas (zones 6 and 7). In the UK, it is said to be hardy down to −10 °C (14 °F), if kept dry in winter. Sun exposure and plentiful water are required in summer for successful flowering. It has gained the Royal Horticultural Society's Award of Garden Merit.
The cultivar E. bicolor 'Alba' lacks all purple coloration and may have reduced odor. It resembles Eucomis autumnalis but can be distinguished by the presence of long flower stalks known as pedicels.
Where it grows
Eucomis bicolor is native to Southern Africa (the Cape Provinces, Lesotho, KwaZulu-Natal, the Free State, and the Northern Provinces). Along the Drakensberg escarpment it is found in damp grassland, often near streams, up to elevations of 2,500 m (8,200 ft).
