Most frangipani varieties flower from December to April but my in ground Singapore here on the Sunshine Coast had numerous blooms before the end of October. Many of my firecracker pinks in pots were also in flower early November.
Hot Pink frangipanis tend to produce foliage and flowers later but hit their peak around March or April.
I’ve never live in the tropics but I assume frangipanis flower all year round in tropics. Feedback anyone?
