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.

Nerine bowdenii

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]

DescriptionEdit

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]

CultivationEdit

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]

This plant has gained the Royal Horticultural Society's Award of Garden Merit.[11][12]

BiochemistryEdit

The bulbs of Nerine bowdenii contain ungeremine, a betaine-type alkaloid, and a number of other alkaloids.[13] 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.[14]

DiseasesEdit

The plant virus, vallota mosaic virus, has been found to infect Nerine bowdenii and other members of the genus Nerine in the UK.[15]
