In several Pacific islands, frangipani is used for making leis and indicate relationship status, whereas in Malay folklore, it is associated with ghosts and demons (pontianak) and is known as graveyard flower, as per discussion in forum here.
I found this rare frangipani in front of a shoplot near my house. This is the second time I've seen this plant in front of shops. Guess it is now a decorative plant with feng shui purposes.
