Sparaxis grandiflora is a very variable South African species, growing between a few inches and about a foot high. The photo, taken today, is of S. grandiflora subsp. fimbriata. It's one of several plants growing in pots under glass in mediterranean conditions, here in Sussex, UK. There are three other subspecies, with flowers in other colours - from cream to violet, yellow or (very rare in cultivation) a deep vibrant plum red.
Like Cali's plants, S. grandiflora does best in mediterranean climates (it does well on rather alkaline clay in our hot Greek garden, where it was flowering a couple of weeks ago), but can tolerate more maritime conditions too. S. grandiflora has the biggest flowers of the genus. It increases well, the many bulblets growing to flowering size quite quickly.
