Singapore Plumeria (Plumeria obtusa): Evergreen Frangipani

Singapore plumeria, or Plumeria obtusa, is a tropical evergreen shrub or small tree prized for its fragrant, white flowers with yellow centers. Unlike many plumerias, it retains its leaves year-round in warm climates.

Botanical Profile

Description and Features

This species grows 10–25 feet tall with a broad, rounded canopy. Leaves are dark green, glossy, oblong, with blunt tips (obtuse). Flowers are 2–3 inches wide, pure white with a yellow throat, intensely fragrant, especially at night. Blooming occurs nearly year-round in tropical conditions.

Cultivation and Uses

Singapore plumeria requires full sun, well-drained soil, and frost-free conditions. It is drought-tolerant once established but benefits from regular water during growth. Commonly used in leis, temple plantings, and as a specimen tree. Can be grown in containers and brought indoors in cooler climates.

Care

Fertilize with high-phosphorus formula to encourage blooms. Watch for rust fungus on leaves.
