We have grown our plants in full to part sun and irrigate regularly only because they are in containers but since this plant hails from an extremely dry climate, we suspect that it can be grown without much irrigation. There is a planting in the ground at the Fullerton Arboretum growing well in part day sun with only occasional irrigation. Hardy to at least 28F. A very showy and unusual plant in bloom but with little cultural information available.

Trichodesma has about 45 species native to tropical and subtropical regions from Africa to Asia and Australia. Trichodesma scottii is a little-known species that from the island of Socotra (Yemen) where it grows in mountain thickets. Our plants were grown cutting grown from seedling plants from seed collected off plants grown in cultivation in the United States that were originally from seed collected in 1999 at Jebel Haghir, Soqotra (Socotra) Yemen. We grew and sold this unusual plant from 2007 until 2015. 

This information about Trichodesma scottii displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
