Romulea is a genus in the Iridaceae family of about 90 species that is found both in South Africa and in Europe. Rootstock is a corm, globose, bell shaped to top shaped, compressed or asymmetric with a circular to crescent shaped basal ridge. This genus has flowers reminiscent of Crocus. Many are quite striking, especially the South African species and there is a great variation in colour and markings of the flowers. They are easy to grow in pots and many are easy from seed, flowering rather quickly in some cases.

Romulea pratensis is a South African endemic species found in the Eastern Cape and Western Cape provinces where it grows in grassland. Reaching 12 to 25 cm tall, this species has a corm with an oblique basal ridge and sharply bent over fibrils. The flowers, borne in winter, are white, lilac, or rose coloured, often with one to three dark lines in the throat, and with a greenish yellow cup. The outer segments are brownish purple or green with dark lines on the backs.
