Reproductive flower parts are hidden deep within the narrow floral tube. In the Caribbean, the hummingbird has evolved alongside the frangipani, and acts as a pollinator. While in Costa Rica Plumeria rubra is pollinated by a number of different hawkmoth species. Pollination of this species is achieved through 'floral mimicry'; no nectar is produced in the flowers as a reward for pollinators. Hawkmoths are attracted to the flowers of Plumeria because they mimic the floral cues, including scent and visual cues, of nectar-producing flowers.
There are no specific pollinators in Australia, and growers generally pollinate flowers by hand using fishing line. Bean like seeds pods are produced within 2 weeks of pollination, but take 9 months to mature.
Plumerias do best in slightly acidic soil, and warm temperatures. They do not need a lot water to survive. They are frost tender, so in Australia grow best in warm coastal climates.
The latex of Plumeria has been utilised in tropical regions for medicine for the treatment of itches, swellings, and fevers.
Not generally known to be weedy.
