Berula repanda

Berula repanda is a luxuriantly foliaged plant, ideal for a garden pond or wet patch, and it is in full flower now.

Berula repanda is an evergreen, rhizomatous perennial that grows up to 1.5 m tall. It has striking, simple, pinnate leaves which are marginally toothed and borne on hollow stems. The flowers are arranged in compound umbels and have creamish petals and numerous persistent involucral bracts. The fruit consist of two mericarps, each with 5 ridges and reddish-brown when ripe. It flowers predominantly from January to April during the warm summer months (Hiern 1896; Townsend 1989).

Conservation status
Berula repanda is treated as Least Concern (LC) in the Red List of South African Plants (Raimondo et al . 2009).

Distribution and habitat
This species is widely distributed from Cameroon and Tanzania southwards to Angola, Mozambique and South Africa, where it is locally common in wet areas along stream banks.(Townsend 1989).

 Derivation of name and historical aspects
The genus Berula, until recently, comprised only a single species, B. erecta . However this concept was expanded by Spalik et al. (2009), to include the monotypic genus Afrocarum and three species previously placed in Sium. The genus now comprises six species, four of which are restricted to Africa (of which two are endemic to St Helena). The generic name is a distortion of another well known Apiaceae genus, Ferula, commonly called hog's fennel (Trinder-Smith, 2003). The specific name repanda refers to the slightly uneven and wavy leaf margins that distinguish it from the similar B. thunbergii .

Uses and cultural aspects
We are not aware of any cultural or medicinal uses for this species. However, Berula thunbergii is used traditionally to treat toothache and has been reported to be poisonous to livestock, while, in contrast, the stems of B. bracteata are eaten raw in St Helena (Watt & Breyer-Brandwijk 1962).

Growing Berula repanda

This plant needs to be grown in a very wet position preferably along the banks of a pond or potted up in the pond where they will tolerate full sun or semi-shade. As it grows from a creeping rhizome it can be propagated vegetatively by subdivision of the rhizome. This species is the dominant planting along the edge of the Otter Pond in Kirstenbosch Botanical Garden, Cape Town, where it can be seen growing together with Alsophila dregei (tree fern), Wachendorfia thrysiflora and Crocosmia x crocosmiiflora .
