Wiliwili is a large, striking, dry forest tree with brilliant orange flowers and bright red seeds. Most wiliwili flower synchronously; when out of flower they have shocking orange bark from an associated alga.
trees suffer tremendous loss of seed to predation from a weevil, but viable
seeds can be found with sufficient persistence. A warm water soak or mechanical
scarification of the seeds can enhance germination rates. Seeds have a high
germination rate and seedling grow quickly.
is extremely fast-growing in height and girth, potentially reaching a meter or
more in a single year. They will rapidly outgrow pots and care must be taken to
avoid root bound potss. In cultivation, the plants are very susceptible to
spider mites and powdery mildew; they will sometimes outgrow the mildew but the
mites should be treated or they may prove fatal. Wiliwili are drought deciduous
and when stressed the plants will typically drop their leaves, however,
wiliwili are resilient plants and with continued care they will sprout again.
