TROPICAL PLANT ENCYCLOPEDIA

Dwarf Ylang-Ylang, small tree or shrub with highly scented flowers. This is one of the most desired and sought after rare fragrant plants. It is pretty easy to grow, stays compact and in nice tree-like shape. Flowers smell as great as full size Ylang Ylang tree, although sometimes fragrance may be less intense and requires warm and humid conditions for full aroma. The plant blooms year round providing warm conditions. It can be also grown as a container and a house plant, but keep in mind it requires bright light for profuse flowering.
This plant is seasonally sensitive: during cooler months leaves may drop or get yellow/dark spots. New leaves will regrow with warm temperatures (above 70F). It is still available for purchase but do not order if leaves appearance matters to you.
