Culture
Plumerias are tropical plants and should be protected from frost. Exposure to just one freeze will kill these flowers. They are drought and heat tolerant, and can be grown either in full sun or partial shade, although plumerias will tend to flower better in full sun. In the fall, the leaves of the plumeria will turn red and drop off. Plumerias are dormant in the winter and require no special care until they begin to grow in the spring, at which point they need water.
