Frangipani (Plumeria rubra) are popular, especially in older gardens in this country and have been here for so long that it is easy to think they belong here. However, like a number of ornamental trees here they are exotic, apparently originating from Mexico, Central America, Colombia and Venezuela. They are fairly innocuous as alien vegetation goes.
Their popularity in tropical and sub-tropical gardens probably stems from the sweet fragrance of their flowers which last throughout the summer. Here you can see a cluster of buds about to open.
These ones open to a pale creamy pink.
While others are a dark pink.
The attractive trees are covered with long leaves.
