A new plant in cultivation originated from South Africa. It is very similar to more common species Clerodendrum ugandense (Blue Butterfly Bush) other than color and smaller size of the flowers which are in tighter panicles.

It grows into a vigorous large size bush with multiple stems. Unlike most clerodendrums, it is very difficult to propagate and cuttings don't root very easily. Small plants grow very slowly but even at 1 ft tall they start flowering. Once etablished, the bush grows fast, producing many branches.

Cultivation is pretty simple and the plant needs only average maintenance - regular water and well drained soil. It needs full sun for flowering. Pink Butterfly Bush is more cold sensitive than Blue Butterfly Bush (C. ugandense). However even after a cold snap and leaf damage, plants regrow well from the main stems.

Originally we have obtained this plant in 2014 from a rare plant collector, and have been propagating it since. It came to us under name of Rotheca mastacantha. The name Rotheca is often used for plants in Clerodendrum genus.
