Plumeria obtusa aka Frangipani

Plumeria obtusa is a small tree in the dogbane family, Apocynaceae. Its common names include white frangipani and pagoda tree. Some gardeners call it Singapore graveyard flower. Kew places its native range from southeastern Mexico to Honduras and across the Caribbean. It grows in tropical regions with a dry season. People have also introduced it to other tropical areas worldwide.

The tree has a rounded shape and can grow as a shrub. Garden trees often reach 10–15 feet [3–4.6 metres] tall. Some reach 25 feet [7.6 metres], with reported spreads reaching the same size. The glossy, dark green leaves have narrow bases and wider ends. Their blunt tips help explain the species name, obtusa. Leaves can reach about 0.7 feet [0.2 metres] long. The foliage stays evergreen in some places. In climates with dry winters, the tree may lose many leaves.

White flowers have five petals and bright yellow throats. Each flower can span about 0.15 feet [0.04 metres]. They grow in clusters and have a strong scent. Flowering runs from spring through fall. The largest flush often comes in July and August. The fruit takes the form of cylindrical seed pods. In Hawaii, people use the blooms for leis and perfume. The flowers and scent make this tree useful near patios, decks, and porches.

Grow it outdoors in frost-free sites within USDA zones 10–12. Full sun suits it best, though it accepts light shade. It needs rich loam that drains well. Soil can range from dry to moderately moist, but should not stay wet. The tree tolerates drought. In colder areas, grow it in a pot or greenhouse. Use a sandy potting mix with good drainage. Bring pots indoors for winter and keep them at 50–55°F. Reduce watering sharply during this cool rest. Stem cuttings provide an easy way to raise new plants.

Serious pest and disease problems are not usually reported. Still, watch for scale insects, mealybugs, thrips, whiteflies, and nematodes. Soil that stays too wet can lead to root rot. Good drainage matters both in pots and in the ground. The supplied sources describe ornamental uses, not food uses. They provide no species-level evidence on edibility or toxicity.
