Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Christian Friedrich Ecklon and named after the German botanist and medical practitioner, Friedrich Freese.
Freesias are herbaceous plants which grow from a conical corm 1โ2.5 cm (1โ2โ1 in) diameter, which sends up a tuft of narrow leaves 10โ30 cm (4โ12 in) long, and a sparsely branched stem 10โ40 cm (4โ16 in) tall bearing a few leaves and a loose one-sided spike of flowers with six tepals. Many species have fragrant narrowly funnel-shaped flowers, although those formerly placed in the genus Anomatheca have flat flowers.
