Flowering time is from spring to summer. After flowering, the tree forms clusters of small round fruit which turn red in autumn and hang on the tree until well into winter. These attract birds to the garden. This is a very difficult species to propagate, from either seed or cuttings. Numerous techniques have been tried, with air layering giving the best results.
Germination is erratic and can take up to nine months.
Do not allow the mixture to dry out at any stage. Olinia emarginata can withstand frost, but not drought.
