The bush violet, as Tinnea barbata is commonly known, will occasionally reach 3 m in height. It grows in a small area at high altitude on the mountains near Barberton in Mpumalanga. The plant should be cold resistant, given the habitat.
The 19 known Tinnea species are all from Africa. They form part of the Lamiaceae family. Tinnea barbata is grown in gardens, sometimes from seed as is done at Kirstenbosch. It should thrive in shade if moderately watered. The other Tinnea species found in South Africa have brown flowers (www.plantzafrica.com).
