Othonna Triplinervia Asteraceae

The Othonna Triplinervia is a thick, evergreen, fleshy-stemmed (pachycaul) shrublets with short branches and leaves crowded at the tips. It grows in crevices and on ledges of sheer, east-facing aspects on mineral-poor quartzitic sandstone soil. Rainfall occurs during both winter (cold fronts) and summer (mainly thunder showers) and amounts to about 500–600 mm per annum. The average daily maximum temperature is about 26°C and the average daily minimum temperature is about 11°C. Winters are cooler but frost is rare or absent.

It shares its habitat with other cliff-dwelling plants such as Haworthia gracilis var. picturata, Haworthia viscosa, Cyrtanthus montanus, Plectranthus verticillatus, Gasteria glauca, Crassula lactea and Lampranthus affinis. The plant has been well established in cultivation (ex situ conservation) and is grown by succulent plant growers all over the world.
