Description

Plumerias can grow to be large shrubs or even small trees. In tropical regions, Plumeria may reach a height of 30 to 40 inches (76 to 101 centimeters) and 20 inches (50 centimeters) wide. They have widely spaced thick branches, round or pointed, long leathery, green leaves in clusters near the branch tips. The leaves are oblong, lance-shaped, to 20 inches (50 centimeters). During the early summer through the early fall months Plumeria rubra produces very fragrant clusters of showy, waxy flowers in various shades of rose and pink. All parts of the plumeria are considered toxic and the sap can cause a rash in sensitive people. But the alkaloids in plumerias make the plant extremely bitter and there are no definitive cases of plumeria poisoning.
