The genus Ammocharis in the Amaryllis Family (Amaryllidaceae) is endemic to Africa. They are herbaceous perennials growing from a true bulb. The flowers are borne in an umbel, a cluster at the top of the peduncle or stalk.
Ammocharis is closely related to Crinum. Like Crinum, it has fleshy seeds that do not go dormant ("recalcitrant"). For two species of Ammocharis, the seeds appear to be dispersed by wind.
There are several species in the genus:
Checklist of the genus Ammocharis.
These plants can grow in partial shade to full sun.
They seem to prefer growing in large pots; I have most of mine in 8-inch or 10-inch round plastic pots planted in a gritty mix.
Feed with a dilute soluble fertilize when the plant is in active growth. This depends on the species. For summer-growing and opportunistic plants, this will be from late winter or early spring onwards. In late summer, stop feeding. In winter, reduce watering or cease watering completely.
For winter-growing species, grow in protected spot away from frost. Water from early autumn on until growth slows or stops in Spring.
Not frost-hardy, so protect from freezing.
