This is a native, endangered plant of Hawaii, where it is also the state plant. It can be grown as an annual as it flowers early from seed. If perennial it usually reaches around 10ft in the garden, but can be larger. Fast grower, needs little watering, can flower twice a year, each bloom time lasting about 2 months.
