Chasmanthes

Chasmanthes are bulbous plants with the appearance of Crocosmias that belong to the iris family, just like gladioli and irises.

Originating from South Africa, like Chasmante floribunda, the most commonly planted species, these perennials are not very hardy and are most often grown in pots outside the mildest regions. Chasmanthes form beautiful clumps of linear, upright, fresh green leaves, dense and vigorous, and flower from spring to summer, for several weeks. Clumps of leaves emerge from robust flower stalks, 80cm (32in) to 1.5m (5ft) tall depending on the varieties, adorned with long, thin tubular flowers in shades of orange, red or yellow, arranged in two rows.

Chasmanthes are grown like gladioli outside of mild climates. On the Mediterranean coast, they flower from spring and lose their leaves in summer, when they go into dormancy. These bulbs appreciate sunny to semi-shaded exposures and light, moist, well-drained soil. You can plant them in spring or autumn, under 10cm (4in) of soil. It is perfectly possible to overwinter the bulbs in a dry and cool place, or to bring the pot indoors to protect it from frost and humidity.
