Nerine bowdenii |
Nerine bowdenii is a species of flowering plant in the family Amaryllidaceae. It is an herbaceous bulbous perennial, growing to 45 cm (18 in) tall by 8 cm (3 in), with strap-shaped leaves and large umbels of lily-like pink flowers in late summer and autumn. [1] The common names of the species are Cornish lily, Cape flower, Guernsey lily, and Bowden lily. However, it is neither a true lily nor from Cornwall or Guernsey, but originates from South Africa ( Eastern Cape, KwaZulu Natal, Free State, Drakensberg Mountains). [1] Confusingly the name “Guernsey lily” is also applied to a related species, Nerine sarniensis.
The species was named in 1904 after Athelstan Cornish-Bowden who had sent bulbs of the plant to England from South Africa. [2] [3] [4]
N. bowdenii bulbs are 12 to 14 centimetres (4.7 to 5.5 in) in circumference. [5] The bulbs are "shaped like old-fashioned Chianti bottles". [4] The plant has eight or more faintly-scented bright pink flowers with frilly tips, resembling finely-cut lilies. [6] Because the leaves do not appear until spring, the species can tolerate lower temperatures than most species in the genus Nerine. [7]
Nerine bowdenii is widely cultivated in temperate regions, where it requires warmth and shelter in colder areas, but is quite hardy, being able to withstand temperatures of −15 °C (5 °F). [4] It needs to be planted where it cannot be disturbed for several years, and blooms best when the bulbs are crowded. The species grows best in heat and well-drained soil. [8] However, it will not tolerate tropical or very humid weather. [9] [10] It is suggested that colchicums and cyclamens are good choices of companion plants to grow with this species. [4]
The following cultivars have won the Royal Horticultural Society's Award of Garden Merit:-
The bulbs of Nerine bowdenii contain ungeremine, a betaine-type alkaloid, and a number of other alkaloids. [16] Ungeremine is an inhibitor of acetylcholinesterase, and as such may be of interest in research into treatment of Alzheimer's disease. Ungeremine also has been isolated from a number of related plant species, such as Ungernia minor, Ungernia spiralis, Zephyranthes flava, Crinum asiaticum, Crinum augustum, Pancratium maritimum and Hippeastrum solandriflorum. [17]
The plant virus, vallota mosaic virus, has been found to infect Nerine bowdenii and other members of the genus Nerine in the UK. [18]
