St Helena ebony (Trochetiopsis ebenus) is not related to the ebony of commerce but is instead a member of the cocoa family (Sterculiaceae). It is now critically endangered in the wild, being reduced to two wild individuals on a cliff, but old roots are sometimes found washed out of eroding slopes (relicts of its former abundance). These are collected on the island a used for inlay work, an important craft in the island of St Helena. A related species, the dwarf ebony (Trochetiopsis melanoxylon) is now completely extinct.
It is quite easy to propagate from cuttings and many island gardens now boast a fine ebony bush. It is related to the St Helena redwood (Trochetiopsis erythroxylon) and a hybrid between them (Trochetiopsis x benjamini) is also now often planted.
