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 rosea var. australis, synonymously known as Romulea parviflora and commonly known as Froetang, Frutang, Knikkertjie, Perdefroetang or Spruitjie in Afrikaans and Pink Romulea or Rosy Sandcrocus in English, is a South African endemic species found in the Eastern Cape and Western Cape provinces. From late summer to early winter and again from mid-winter to late spring it produces magnificent pink flowers with yellow cups and distinct dark stripes on the reverse side.
