Tigridia is a genus usually quoted as having 30-35 species though I have a list of over 80 names. Most are from Mexico and C. America with outlying species in Peru and Chile. Four plants previously called Rigidella are now included in Tigridia. Few are in cultivation, with the exception of the Mexican R. pavonia which has been cultivated for perhaps a thousand years.
They grow from a tunicated bulb (not a corm) with a fan of pleated leaves below a spike of amazing flowers. In some species the flowers face up, in others they nod. They are all fugacious, each bloom lasts but a day, however most produce a succession.
Most are summer-growing and winter-dormant, adapted to a dry winter rest. This makes them ideal for cultivation though they must be totally dry when dormant. Climatically they range from alpine to maquis, from marsh to woodland.
They like a well-drained medium and lots of feeding will ensure that they make more abundant growth, increase and flowers. Most of the species in cultivation seem to be cold hardy though I have not grown the semi-tropical species.
