Origin: Mexico.

Opinion
"
Choisya ternate will grow in any type of well-drained soil. It can be planted in full sun,however it is best planted in a sheltered area. It is tolerant to drought and light frost, but it does the best in mild winter locations. It needs protection from the hot afternoon sun, and it does best if it is planted facing south, west or east. Stems have to be pruned immediately after flowering to encourage summer or autumn blooms. Propagation can be done by cutting stems in the summer. Flower and leaves both have an orange scent and it attracts butterflies and bees.
