Plumerias, also known as lei flowers or frangipani, are small, fragrant, flowering trees native to Mexico, the Caribbean, and parts of South America. There are several species of plumeria grown as ornamental trees, all members of the dogbane family. In a tropical garden, they are a great addition with pretty flowers and fragrance.
About PlumeriaPlumeria grows in tropical climates. While the plants are fairly tolerant of both salt and windy conditions, they’re not tolerant of cold. In the proper growing conditions they bloom freely from spring throughout the fall and are often grown in the garden as an ornamental shrub or small tree.
Some of the species in cultivation are Plumeria rubra, Plumeria obtuse, and Plumeria alba. Plumeria has a rounded canopy and grows about as wide as it does tall. The lees are long ovals, glossy green, and grow in clusters at the tips of branches. This beautiful plant does best in USDA hardiness zones 10-12, and doesn’t tolerate cold temperatures.

The plumeria flower is tubular with five pinwheeled petals. Its colors can be white, red, pink, yellow, or multicolored. The flowers are crafted into leis in Hawaii. They emit a strong, pleasant fragrance, and at night they attract moths as pollinators.
Although not native to the U.S., plumeria is not considered invasive. It is used as an ornamental tree in yards, gardens, and other planned landscapes. It can also be grown in a large container and overwintered in colder areas. It will not tolerate any winter frost.
Plumeria Water & Light RequirementsA plumeria tree does best in 6 hours of full sun. It has medium moisture requirements, meaning its soil should drain well and never get soggy, but should not be allowed to completely dry out either. It is best to water deeply and less frequently, reducing watering frequency in cooler temperatures. Resume regular watering as new growth appears in spring.
Plumeria Soil & FertilizerThe most important property of the soil for plumeria is that it drains well. Loamy soil that is slightly acidic is best. When growing plumeria plants in pots, use a coarse, well-draining potting mix, using a cactus mix or perlite and sand. Fertilize plumeria a few times during the growing season. A product with more phosphorous, such as 10-30-10, will promote more flower growth. Giving them too much nitrogen will only result in more foliage growth and less flowering

It damages easily in the cold, so don’t grow this tree if you get freezing temperatures in winter. Alternatively, you can grow it in a container and move indoors as needed. Root rot can be oided by providing soil with drainage and by not overwatering.
Plumeria rust is a fungal disease that can cause problems. Look for orange spots on the undersides of lees. It is not often bad enough to harm the tree. Simply collect affected lees and dispose of them.
Some of the pests that might attack plumeria include mealybugs, scale, and whiteflies. These can lead to sooty mold on the lees because of the honeydew they produce. Control the insects to prevent mold.
Pruning PlumeriaLate winter and early spring before new lees emerge is the best time for pruning a plumeria. Trim off any diseased or broken stems. Otherwise, prune plumeria to maintain a desired shape or size as needed, up to 12 inches (31 cm) from the ground in late winter or early spring (prior to new growth). Any drastic or hard pruning may reduce flowering.
Indoor Plumeria CareKnowing how to grow plumeria indoors allows those of us not living in the tropics to enjoy this beautiful tree. Use a large container to grow plumeria indoors. When there is no risk of frost, you can enjoy the container outside. It makes a pretty, fragrant addition to a patio or deck.
To overwinter containerized plumeria indoors, let it go dormant. The lees will turn yellow and drop off. You can then store the plant in a spot inside, with or without light. Water only infrequently through the winter. Don’t let the soil get bone dry, but do water much less than you would outdoors in summer.
You can propagate plumeria plants by cuttings or seeds in spring, with cuttings being the easiest and most preferred method. Insert cuttings about 2 inches (5 cm) in potting mix and water thoroughly.
