Шаблон:Short description Шаблон:Use dmy dates Шаблон:Speciesbox
Eucomis bicolor, the variegated pineapple lily or just pineapple lily,[1] 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).[2] The pale green, purple-margined flowers are arranged in a spike (raceme), topped by a "head" of green leaflike bracts. It is cultivated as an ornamental bulbous plant, although its flowers have an unpleasant smell, attractive to the main pollinators, flies.
Description
Eucomis bicolor is a perennial growing from a large bulb. It reaches Шаблон:Cvt in height, with a basal rosette of wavy leaves Шаблон:Cvt long. In late summer (August in the UK), it produces a stout stem (peduncule), often with purple markings. The inflorescence is a raceme of pale green, purple margined flowers with tepals up to Шаблон:Cvt long, borne on pedicels Шаблон:Cvt long. The inflorescence is terminated by a head (coma) of pale green leafy bracts, sometimes tinged with purple. At close quarters the flowers have a strongly unpleasant smell. The ovary is green.[3][4][5]
The homoisoflavanones eucomin, eucomol,[6] (E)-7-O-methyl-eucomin, (—)-7-O-methyleucomol, (+)-3,9-dihydro-eucomin and 7-O-methyl-3,9-dihydro-eucomin[7] can be isolated from bulbs of E. bicolor.
Taxonomy
Eucomis bicolor was first described by John Gilbert Baker in 1878.[2] The specific epithet bicolor means "two-coloured";[8] the tepals are pale green with purple margins.[3] It is one of a group of larger tetraploid species of Eucomis, with 2n = 4x = 60.[9]
Distribution and habitat
Eucomis bicolor is native to Southern Africa (the Cape Provinces, Lesotho, KwaZulu-Natal, the Free State, and the Northern Provinces).[2] Along the Drakensberg escarpment it is found in damp grassland, often near streams, up to elevations of Шаблон:Cvt.[3]
Ecology
Eucomis bicolor is primarily pollinated by flies, including blowflies, house flies and flesh flies, attracted by the sulphur compounds in the scent of the flowers.[10]
Cultivation
In cultivation, Eucomis bicolor is not fully frost-hardy. In the US, it is classed as hardy in USDA zones 8–10, and requires a winter mulch in colder areas (zones 6–7).[1] In the UK, it is said to be hardy down to Шаблон:Cvt, if kept dry in winter. Sun exposure and plentiful water are required in summer for successful flowering.[3] It has gained the Royal Horticultural Society's Award of Garden Merit.[11]
The cultivar E. bicolor 'Alba' has plain white flowers and lacks any purple coloration. It resembles Eucomis autumnalis but can be distinguished by the long flower stalks (pedicels).[3]
