Botanical Name: Plumeria rubra
Plumeria care is easy as long as you can meet its needs for warm sunshine and humidity. Vigorous and a prolific bloomer, Plumeria rubra makes a beautiful potted house plant.
Thick, woody branches carry pointed leaves that grow up to 1 ft (30 cm). Big clusters of fragrant flowers grow like bouquets on branch tips from early summer through fall.
Frangipani flowers are each made up of 5 overlapping petals. The waxy blooms are about 2 in (5 cm) wide and are available in many shades of pink, red, yellow or white -- or any combination.
These flowers are among the most fragrant of any tropical flowering plant. Its essential oil is commonly used as fragrance for perfume, lotion, candles and other scented products. These tropical plants are a common sight in Hawaii, where the fragrant plumeria flowers are used to make flower leis.
This Central American native prefers bright light and moderate humidity. If you can give plumeria care what it needs, you'll enjoy this spectacular tropical plant in your home for many years.
Let the sun shine in. Plants that don't bloom aren't getting enough sun. Growing plumeria require at least 5 hours of direct sun each day.
Repot young plants in spring when their roots have filled the container. Move it to a pot only one size larger. When planting plumeria, care should be taken to choose a pot with drainage holes to prevent root rot. Is it too big to repot? You can top-dress it instead by removing the top 2-3 inches of soil and replacing it with fresh soil.
Prune it back. You can control its size and encourage it to branch out by regular pruning. Flower clusters grow from the branch tips, so you'll get more flowers this way. Cutting plumeria branches back by 1/3 won't hurt it at all -- this is a vigorous plant. Prune in late winter or early spring.
Give it a winter rest. Frangipani tree will go dormant in the winter months, shedding its leaves and requiring a cool rest. Put it in a cool room -- a basement or garage is ideal as long as the temperature doesn't drop below 55°F/13°C. Water sparingly and stop fertilizing until new growth begins in spring.
Although it's called a frangipani tree, this tropical plant is actually a shrub. Out of 300+ species of Plumeria, rubra is the best for growing indoors.
