Polyscias fulva is usually grown from wild seedlings, although in Umalila, Tanzania the tree is also planted using stakes. Seeds can also be used: collect the fruits immediately they turn purple-black on the tree. Allow them to mature in the shade for one or two days then extract the seed by soaking the fruits in cold water for 4-6 hours. Squeeze out the seeds which will float in the water, then dry them in the shade. 7% of seeds germinate after 35-45 days. Seeds can be stored for up wo years.
Flowers of Polyscias fulva are green “yellow and honey scented
