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 multisulcata grows 30-50cm in height. During spring it bears stunning buttercup yellow flowers. It occurs in the Northwest Cape where it is found growing in seasonal ponds where the corm and base of the stem are embedded in mud. It has two long erect grooved leaves.
