Plumeria: Greenhouse Plants
W – warm, minimum of 13°C (55°F) / T – tropical, minimum of 18°C (65°F)
Plumeria rubra is the Frangipani or West Indian Jasmine. It is a beautifully exotic scented plant which must have tropical conditions to grow well. It can tolerate lower temperatures during the winter, though, provided it is kept almost dry and dormant, in which case it will become deciduous. Plants kept in greater heat will retain a few leaves at the top of the plant. I suppose, with their long thick mostly leafless stems, they could be described as ugly. However, they redeem themselves by producing heads of rose, yellow or white flowers towards the end of summer. To do this they must have good light. P. r. acutifolia (sometimes known as P. acutifolia or even P. acuminata) has white flowers with a yellow centre. Cuttings 15-20 cm (6-8 in) long can be taken in spring. The key to success with these is to keep them warm but not too humid and certainly not wet. Seed is obtainable and plants will begin flowering as very small specimens of 23 cm (9 in) upwards.
