About
Alsophila dregei, synonym Cyathea dregei, (common tree fern or gewone boomvaring in Afrikaans) is a widespread species of tree fern in southern Africa.
Within South Africa, it co-occurs with the indigenous forest tree fern (Gymnosphaera capensis) and the invasive Sphaeropteris cooperi from Australia. Further north, outside of South Africa, it coexists with an additional two tree fern species, A. manniana and A. thomsonii.
How to grow it
Alsophila dregei is rarely common in cultivation as an ornamental plant, especially in South Africa and Australia. Plants should be sheltered and grown in rich humus, with a constant supply of moisture. This species can survive light frosts with little damage.
Where it grows
It is distributed widely in sub-Saharan Africa, including Guinea, Sierra Leone, Ghana, Nigeria, and Cameroon in west and west-central Africa, and in eastern and southern Africa from the Democratic Republic of the Congo and Uganda to South Africa. It is also native to Madagascar. In West Africa it grows in mountain and plateau grasslands and woodlands from 2,500–7,400 feet (760–2,260 m) elevation.
