Plumeria, or frangipani, is a small tropical tree with waxy flowers and a rich, sweet scent. In Hawaii the blooms are strung into traditional leis, and in Southeast Asia plumerias grow beside temples. You can grow one indoors if you give it plenty of sun and the right winter rest.
Plumeria belongs to the dogbane family and comes from tropical America. It is named after the French botanist Charles Plumier. The flowers are white with a yellow centre, pink, red or multicoloured, and are most fragrant in the evening and at night.
Careful: milky sap
Like other members of its family, plumeria has a white milky sap that can irritate skin and eyes and is poisonous if swallowed. Wear gloves when pruning or taking cuttings, and keep the plant away from children and pets.
In autumn, as the days shorten, plumeria slows down and may drop some or all of its leaves; this is a normal rest period. Keep it somewhere bright at 15–18 °C and water very rarely, just enough to stop the trunk shrivelling. When new leaves appear in spring, gradually increase watering.
Why plumeria does not flower
Too little sun is the most common reason.
The plant is still young: a rooted cutting usually flowers within 1–3 years, a seedling later.
Too much nitrogen fertiliser gives leaves instead of flowers.
Usually rot from overwatering during the cool season. Cut back to healthy tissue and water less.
Can plumeria be grown from seed?
Yes, but seedlings may not match the parent’s colour and take longer to flower.
