The genus Nerine consists of about 25 species, depending on what is recognised and which species are lumped in together. It is closely related to another African genus - Brunsvigia.
With regard to cultivation and treatment, there are three main groups - winter-growing, summer-growing and evergreen species. Although some are very common and others are limited in distribution and extremely rare, none are difficult in cultivation. The only watch point is to allow for their correct time of growth and dormancy.
Some of the species are simply so tolerant, that they can be grown in the garden, and a vast array of hybrids has been developed. Whilst not disdaining these colourful hybrids, we specialise in growing the rarer, species, types.
A review of species, still useful despite its age, is by Traub, Plant Life, 1967.
