Plumeria spp.
Plumeria is a long-lived tropical focal plant with fragrant, waxy flowers from late spring into fall. At about 15 feet tall and 12 feet wide, it reads as a small tree or substantial shrub rather than a filler planting. Give it a place where its branching silhouette and flowers can be seen from a patio, entry, or main path, while leaving open sky above for its full-sun habit.
Space Plumeria 10 ft apart, measured center to center (3 m).
The mature spread is about 12 ft (3.7 m), so plants set at that distance grow together into a connected screen.
Treat 10 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.
Use Plumeria spp. as a warm-climate specimen near a terrace, pool surround, courtyard edge, or broad foundation bed, not in a narrow side yard or tight border. Set it back from walls, eaves, gates, and regularly used paths so the mature canopy does not crowd circulation. In areas colder than its outdoor range, keep it in a large movable container and reserve a protected indoor overwintering location before the first cold weather.
Plant on 10-foot centers when repeating plumeria in a loose screen or grove. Each plant can ultimately occupy a canopy about 12 feet across, so that spacing allows neighboring crowns to meet or overlap rather than remain separated. For a single specimen, protect a roughly 12-foot-wide planting zone and leave additional clearance toward paths, doors, and outdoor seating for pruning and everyday access.
Place plumeria in full sun, with open exposure rather than shade cast by a building or taller tree. Use a well-drained bed or container mix, especially where irrigation or seasonal rain might keep the root zone wet. Once established in the landscape, it tolerates dry conditions, making it better suited to a restrained watering zone than to a frequently irrigated mixed bed.[1]
The flowering season occupies the warm part of the year, from late spring through fall. In winter, plumeria may become dormant and lose its leaves, leaving the branch structure exposed and opening more light around its base. Allow for that changing footprint when planning evergreen screening or winter interest nearby; lower plantings may receive substantially more light while the canopy is bare.[1]
Cold exposure is the main siting constraint. Keep in-ground plants within USDA Zones 10 through 12, and use containers where winter shelter is necessary. Avoid low, poorly drained pockets; a raised bed, slope, or freely draining container position is easier to integrate than a damp basin. Remove fallen leaves from beneath the plant in fall to keep the planting area orderly and reduce carryover of foliar rust.[1]
