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 ligustica is exotic to South Africa occurring in Sardinia and Liguria and also said to occur on the Western Mediterranean coasts of Northern Africa and Southern Spain. This winter flowering species grows to about 10cm tall. It produces lovely flowers that are a soft shade of lilac and pale blue, with a small white throat. This is an extremely rewarding species in cultivation as it has a long flowering period, with several blossoms per corm.
