Brunsvigia is a South African genus of Amaryllidaceae which grow in semi-arid regions. There are both winter rainfall and summer rainfall species that flower with and without leaves at the time. Some produce amazing floral displays. Brunsvigia was the topic of the week for the Pacific Bulb Society list in January 2003. Click on the link to read Bill Dijk's Introduction.

Jim Lykos, who breeds Amaryllids in Australia, has found that the fertility of Brunsvigia flowers depends on the size of the inflorescence and number of leaves. When the inflorescence has a relatively low number of flowers, it is self-infertile. When it has more flowers, the flowers tend to be self-fertile and are also more likely to cross-breed successfully with other Amaryllid genera. The number of flowers produced in autumn is proportional to the number of leaves produced in the previous growing season.
He also found that the plants will sometimes produce one or two seeds per capsule even when crossed with incompatible pollen. The seeds produced by these crosses are apomixic (clones of the seed parent).
