The red currant, Searsia chirindensis, is an attractive, African tree with lovely reddish autumn foliage. It is common throughout the eastern part of South Africa and is often grown in gardens.
The red currant is a semi-deciduous shrub to small tree, 6-10 m high (although exceptional specimens may reach 20 m).
In South Africa it occurs from Swellendam in Western Cape along the coastal belt, through Eastern Cape and KwaZulu-Natal, through the Natal midlands and up the escarpment into Mpumalanga and the eastern part of Limpopo [Northern Province]. In occurs naturally in forests, along forest margins, in riverine bush and scrub forest and rocky hillsides.
The red currant makes an excellent garden tree with its lovely autumn foliage. It is also attractive when in fruit and will attract various fruit-eating birds to the garden.
The red currant is a fast-growing tree (up to 1 m per year) and can be grown in full sun or partial shade. It should be planted in well-drained, composted soil. It does not have an aggressive root system. It should be pruned from an early age if a single-stemmed specimen tree is desired; if left unpruned it will grow into a multi-stemmed large shrub. It will tolerate moderate frosts and is drought hardy.
