Chocolate Bells (Trichodesma physaloides)

Chocolate Bells (Trichodesma physaloides) belong to the Boraginaceae family and looking at the third picture you can see how they got their name. In my opinion, they look good enough to eat. :)

Drooping flowers with large, brownish purple calyces and white corollas characterise this plant which is conspicuous in early spring, especially where grassland has been burnt.
 Distribution and Habitat



Trichodesma physaloides is widespread in the eastern regions of Africa. The species inhabits grassland, woodland, open mixed bushveld, hill slopes, disturbed areas, roadsides, waste places; sandy loam, clay, loam or rocky soils and gravel.
 Ecology



The species of Trichodesma occur predominantly in summer rainfall regions. They are subjected to winter drought, frost and fires. With sturdy, often very old, fire-resistant rootstocks and mass seed production by fire-stimulated flowering, these species are well-adapted to survive unfavourable conditions. Most examples of fire-stimulated flowering plants do flower in the absence of fire, but not as profusely as when subjected to fire.

This plant is not in general cultivation as it does not flower well unless subjected to fire (intense heat). As it is extremely attractive, it presents a challenge to the keen gardener to create an environment to suit it.
