Nerine

Amaryllidaceae

Nerine

They have linear to strap-shaped mid-green leaves which normally follow the flowers. The striking flowers are borne in loose terminal umbels on leafless stems from late summer through to late autumn. Each flower has 6 thin petals which are often twisted. Flowers may be white to pink and red.    

Uses

With the exception of N. bowdenii, they are best grown as greenhouse plants in cold temperate regions. In warm temperate, tropical and subtropical areas they may be grown as container plants, border plants, or in rockeries or xeriscapes.  

Culture

They are half hardy. They do well in most free-draining soils in full sun. Apply a thick layer of organic mulch over the bulbs for winter. Apply weekly liquid feed during the growing season for those grown in greenhouse containers, and re-pot every few years.   

Propagation

Offsets may be lifted and replanted when they have separated from the parent plant. Some species may be divided every 4-5 years when they become overcrowded. Alternatively, plant seeds when ripe. 

Cultivars

There are many named cultivars.

N. bowdenii - to 30-60cm tall. The hardiest species which will usually survive through cool temperate winters. The umbels bear up to 8 pink flowers each to 10-15cm wide. 

N. humilis (syn. N. flexuosa) - to 60cm tall. A tender species. The umbels bear up to 12 pink flowers each to 10-15cm wide. N. f. 'Alba' is a white variety.

Plant Health

They are sometimes prone to a virus disease which can cause chlorosis of the leaves. They are also sometimes attacked by mealy bugs, particularly when grown in greenhouses.
