Croton sylvaticus
 is a member of a large tropical genus represented by several tree 
species in Southern Africa. This extremely attractive tree has a wide, 
spreading, dense, dark green, leafy crown and the long, straight trunk 
of this fast growing species can reach as much as 1 meter in diameter. 
Although the showy, salmon coloured fruits are toxic, various species of
 birds such as the Red eyed Turtle Dove, the Green Pigeon, Cinnamon 
Doves, Weavers and Hornbills find the fruit irresistible. The Forest 
fever tree is host to the well known Green veined Charaxes butterfly and
 numerous insects are attracted to the flowers..

appear, these trees are a truly magnificent sight. Use the Croton sylvaticus
 for any area where a fast growing and attractive shade tree is needed.

Forest fever tree is planted as a single specimen where its beauty can 
be appreciated through all the seasons or whether it is planted as a 
hedge or screen for privacy, this tree deserves to be more widely grown.
