About
Tetradenia riparia is a species of flowering plant native to southern Africa. It belongs in the mint and sage family Lamiaceae. Common names include ginger bush, incense bush, Ibozane, and musk bush. It is occasionally referred to as misty plume bush and is commonly used as a decorative garden plant due to its flowers when in full bloom.
Tetradenia means 'four glands' and riparia translates to 'growing on banks of rivers'.
How to grow it
It is commonly planted in gardens as an ornamental because of its abundant decorative flowering. Fast growing (up to 80 cm per year), the plant will flower in its first year and would prefer occasional watering in summer, though less so in winter. It prefers well drained and well composted soil, and it needs pruning after flowering. It is easily propagated by cuttings.
Where it grows
It grows on the banks of rivers and hillsides, including riverbanks, forest edges, dry woodland valleys and hillsides where there is only minor frost. It is found in eastern South Africa in the provinces of KwaZulu-Natal, Mpumalanga and Limpopo, Namibia, Angola and Botswana and in eastern tropical Africa into Ethiopia.
