Euodia ruticarpa is a deciduous tree growing to 10 m (32ft 10in). The species is hermaphrodite (has both male and female organs).

Euodia ruticarpa is a moderately cold-hardy tree, able to tolerate temperatures down to around -15°c when fully dormant.
Species in this genus tend to be easy to grow, succeeding in mot well-drained soils if given a position in full sun or some light shade.
The plant grows rapidly and well when young, coming into flower early in its life.
A dioecious species – it produces separate male flowers and female flowers, and only one of those types is produced on any individual plant. Therefore both male and female-flowered forms of the plant usually need to be grown if fruit and seed are required

Seed – sow late winter in a greenhouse. Variable germination rates. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Give the plants some protection from the cold for their first winter outdoors.

Cuttings of half-ripe wood (preferably forced in a greenhouse), 5 – 8cm with a heel, early summer to August in a warm greenhouse. Fair to good percentage. Root cuttings in late winter
