Chasmanthe aethiopica thrives in relatively fertile, freely draining soil and will soon spread naturally through division of the corms in favourable situations.
Plants are winter-growing and must be kept dry during their summer dormancy.
In well-drained soil they will survive some moisture during this period but should not be allowed to remain too wet.
The ease with which the species multiplies means that is must be repotted frequently if not grown in the garden.
It flowers best in sunny or partially sunny situations and is a lovely species for underplanting beneath deciduous trees, where it can be left to run free.
Plants should be left undisturbed for optimum flowering.
Potted plants benefit from light fertilizing in the growing period.
