West Indian jasmine (Plumeria alba)
Discover the stunning, fragrant Plumeria alba, or West Indian jasmine. This small deciduous tree offers showy white flowers ideal for tropical landscapes.
Complete Plant Information
Overview
The Plumeria alba, often known by its evocative common name, West Indian jasmine, is prized by tropical gardeners for its distinct vase-shaped habit and intensely fragrant blossoms. This small deciduous tree produces highly ornamental flowers, typically white with contrasting yellow centers, blooming heavily through the warmer seasons. As a member of the dogbane family, Plumeria alba provides significant aesthetic appeal, making it a focal point in warm-climate settings.
This species is native to the Caribbean and thrives in conditions mirroring its origin, demanding high light and well-drained soils. Although mature plants can reach heights of 15 to 25 feet, they maintain a manageable spread, adding vertical interest without overwhelming small gardens. Its beauty is matched by its ease of propagation, often started simply from stem cuttings.
Gardeners value the West Indian jasmine not just for its scent, which is reminiscent of popular commercial perfumes, but also for its structure. While sturdy trees in their ideal range, the upright branches of Plumeria alba are noted as being somewhat weak, making careful site selection crucial. Its performance as a tropical specimen secured its place globally, especially near outdoor living spaces where its fragrance can be fully appreciated.

How to Grow
For successful establishment, plant Plumeria alba in the prime of the growing season, ensuring location receives full, uninterrupted sun exposure for maximum floral production. Soil must be rich, well-drained, and ideally suited to dry to medium moisture levels; avoid consistently wet areas completely to prevent root issues. While established West Indian jasmine tolerates some light shade, flowering will be reduced.
Ongoing care involves maintaining that dry to medium moisture balance. Water deeply but infrequently, especially once established, aligning with its drought tolerance. Pruning is generally minimal, focusing only on removing dead or misplaced branches, being mindful that the thick branches exude a milky sap. As Plumeria alba is deciduous, expect leaf drop and a cessation of blooming during the winter or prolonged dry season.
Gardeners residing outside USDA Zone 10 must adapt their cultural practices significantly. In cooler climates, container growing is mandatory. Use a highly porous, sandy potting mix that mimics their preferred drainage. Containerized plants require an indoor overwintering strategy; reduce temperatures to a cool 50-55 degrees F. and drastically cut back on watering during this dormancy period until spring warmth returns. Propagation is rewarding, as the plant is easily rooted from simple stem cuttings taken during the active growing season.
Landscape Uses
The West Indian jasmine shines as a focal point across tropical landscapes where its size and fragrance can dominate a space. Its vase-like shape and terminal bloom clusters make it an excellent specimen tree near decks, patios, or front porches where visitors can easily inhale the heady scent. In frost-free zones, it serves beautifully as a standalone feature against dark green hedges for contrast.
For gardeners north of Zone 10, container culture transforms this tree into a mobile asset. It can anchor warm-weather container displays throughout summer, moving into bright, cool locations indoors for winter protection. While companion planting options are broad in the tropics, focus on pairing it with low-growing, drought-tolerant flowering shrubs that do not compete aggressively for overhead light or soil moisture.

Noteworthy Characteristics
Plumeria alba, commonly called white frangipani or nosegay, is a small rounded deciduous tree of the dogbane family that grows in a vase-shape to 15-25’ tall. It features fragrant white flowers with yellow centers. Upright branches are thick but weak, and have a milky sap. This species is native to Puerto Rico and the Lesser Antilles, but has been introduced into a number of tropical areas around the world. Very fragrant 5-petaled flowers (to 3” wide) bloom in terminal clusters at the branch tips from spring to fall. Flowers are white with yellow centers.

Potential Problems
This species generally avoids severe insect or disease pressures when grown correctly. Key pests gardeners should monitor for include scale insects, mealybugs, thrips, and whiteflies. Management typically involves regular inspection and targeted application of horticultural oils or insecticidal soaps, particularly during warm, dry periods when pests proliferate. The most significant cultural risk is root rot, which occurs exclusively when soils are overly moist or drainage is deficient. Ensuring the soil remains dry to medium, as preferred by Plumeria alba, is the best preventative measure against this fatal condition.

Conclusion
The West Indian jasmine offers an unparalleled combination of visual beauty and powerful fragrance, making Plumeria alba a must-have for tropical or container gardening collections. Its drought tolerance proves valuable once established in its preferred warm zones. Before planting, confirm your region falls within USDA Zones 10-12 or prepare facilities for essential indoor overwintering.
Propagation Tips
Easily propagated from stem cuttings, the Plumeria alba offers gardeners a straightforward path to multiplying their stock. Cuttings should be taken from healthy, mature wood during the active growing season when the plant is robust. Allow the cut end of the stem to cure or dry for several days until a protective callus forms over the wound; this crucial step prevents rot once planted.
Once callused, insert the base of the cutting into a very well-draining, sandy rooting medium, mimicking the dry soil preference of the mature plant. Keep the medium barely moist and place the cutting in bright, indirect light until vigorous rooting occurs, which may take several weeks. Successful propagation results in new plants that retain the desirable qualities of the parent West Indian jasmine.
Companion Planting
When planning a landscape incorporating Plumeria alba, select companions that appreciate full sun and low to moderate water requirements. Plants suited to the dry-to-medium moisture needs of this tree will thrive alongside it. Consider pairing the fragrant white blooms with vibrant tropical foliage plants that offer textural contrast without intense competition for resources.
Good planting partners might include hardy succulents or xeriscapic flowering shrubs that thrive in similar bright conditions prevalent in Zones 10-12. Avoid placing moisture-loving perennials immediately at the base of the Plumeria alba to ensure the root zone remains appropriately dry, respecting its tolerance for dry soils.
