The 7 species of corms in this South African iris family (Iridaceae) genus are widely cultivated as ornamentals, though some of them are considered weeks in various parts of the world. They have long sword-shaped leaves, sometimes conspicuously veined or pleated, that may be near-evergreen in mild climates. Flowering occurs mainly during summer and autumn, when arching sprays of usually 6-petalled flowers in bright orange and red shades appear. Cultivars cover a wider color range from yellow to rusty brown, and they last well when cut. The genus name, derived from the Greek krokos (saffron) and osme (smell), was given because the classifying botanist noticed a saffron-like scent when water was spilt on a dried specimen. They are commonly known as montbretia.
CULTIVATION
Surprisingly hardy, they are easily grown in full or half sun in moist well-drained soil. In areas where the soil freezes, the corms may be tored dry over winter and replanted in spring. Propagate from offsets, which are often numerous.
Top Tip
Pllant corms 3-4 in (8-10 cm) deep in early spring, and water well during the warmer months. Crocosmia plants multiply freely once established.
