Characteristics
Plumeria (Frangipani, Lei, or Hawaiian palm) is a genus of tropical trees and shrubs valued for their fragrant flowers and repeated blooming, ranging from white and yellow to pink and red, including gradients on the same flower. The flowers are traditionally used in Hawaii for Lei garlands. The plant has a long lifespan and, if given sun and good drainage, is accessible even for beginners attentive to watering.

Growing Highlights
The values below are indicative, not absolute. Variety, size, pot, actual light, and season modify the needs. Plumeria loves warmth and sun. In winter, it may lose its leaves and enter dormancy without meaning it is lost, as long as the branches remain firm. The genus is relatively tolerant of wind and some salt content in the environment but is not frost-hardy.
Light and Temperature
Plumeria requires a minimum of 5–6 hours of direct sunlight per day for robust growth and flowering. Low light can cause pale leaves, elongated growth, abnormal coloration, and lack of buds. The growth temperature is approximately 15–35°C. The plant must be protected from cold—winter temperatures should not drop below about 10°C.
Watering
During active growth, Plumeria requires abundant watering, then the substrate should visibly dry before the next watering. The succulent stems store water: the plant tolerates short substrate drying better than stagnant water, especially at low temperatures. After mid-autumn, as days shorten, watering frequency decreases; in spring, the water amount gradually returns to normal. Frequent misting and watering on leaves or flowers should be avoided—they can accelerate yellowing and premature loss of flowers and leaves.
Substrate and Fertilization
A slightly acidic to neutral, very well-drained soil is necessary: peat or coconut fiber with perlite or pumice and a mineral fraction (coarse sand, for example about 10% by volume as a guideline). A suitable readily available product as a very well-draining base is Professional substrate for cacti, succulents, and Adenium. Adjust watering: good drainage does not mean daily watering.
Fertilization. During the growing season, every 2–3 weeks. For flowering, a fertilizer richer in phosphorus is useful; a common reference in Plumeria culture is an NPK of 10-30-10 or a quality flowering plant fertilizer without excess nitrogen. Excess nitrogen favors foliage over flowers. The dose is adapted to the variety and vigor of the plant, and the fertilizer is applied to already moist substrate. In winter dormancy, fertilization is stopped (if the plant has no leaves) or greatly reduced (if it retains some foliage).
Winter Dormancy
In autumn, especially as days shorten, Plumeria may lose all its leaves, and growth stagnates. During dormancy, watering is drastically reduced or stopped, depending on temperature and how firm the trunk is. If watering is stopped, occasional fine misting on the trunk may be sufficient in very dry spaces, without fully watering the cold substrate. Gradually resume watering when new growth and leaves appear in spring. A leafless plant with firm branches is not automatically unhealthy.
Leaves, Pruning, Pests
Plumeria usually keeps leaves mainly at the growth tips. Degradation of old leaves throughout the year is common and can be accelerated by transport, repotting, seasonal changes, inconsistent watering, or lack of fertilization. If deficiencies appear on new growth, correct the identified factor and remove wilted leaves. Leaf drop after transport or moving is frequent; recovery is usually quick under good growing conditions.
Formative pruning is done at the end of winter or early spring, before growth; severe pruning can delay flowering. Regularly check the plant to prevent attacks by spider mites, mealybugs, thrips, whiteflies, and leaf miners. Frangipani rust may appear as orange pustules on the underside of leaves; it is rarer in the EU, but if it appears, remove affected leaves and improve air circulation/ventilation. For treatments, you can consult the treatments section.
Propagation
For choosing between seeds and cuttings, fruit maturation, callus, rooting, and planting, read the separate Plumeria propagation guide.
Frequently Asked Questions
Is it lost if it loses its leaves in winter?
Not necessarily. If the branches are firm and not rotting, it is often normal dormancy. Check watering: excess water in cold is more dangerous than controlled drying.
Why does it not flower?
Common causes: insufficient sun, too much nitrogen, plant too young from seeds, or too drastic pruning before the season.
