General Description

The tropical hibiscus 'Hawaiian Sunset' freely displays its romantic, deep yellow and orange blossoms that are cup-like with recurving petals. Each petal is rich yellow with red veins and quickly turns into a bright orange and finally a rosy orange at the base. Hibiscus rosa-sinensis is an evergreen shrub that originates from China, and 'Hawaiian Sunset' is a hybrid derived from two cultivated varieties. This tropical hibiscus is vigorous and blooms profusely over an extended period of time.

The flat, glossy leaves of 'Hawaiian Sunset' are kelly to dark green and oval-shaped with small teeth. Its flowers are medium sized, radial and gently cup-shaped with recurving petals. In the glossy rose-orange center of each is a long red floral column that turns orange under a bottlebrush of light yellow anthers and orange-red stigmas, adding more floral splendor.

Tropical hibiscus is heat tolerant, excelling in full to partial sun and acidic to neutral, fertile soil with good drainage. Very poor and alkaline soils lead to nutrient deficiencies. Remove spent flowers' developing green seed capsules to promote continual production of new blossoms. Tropical hibiscus is a garden staple in both tropical and temperate landscapes. This vibrant, large growing cultivar can be grown in sunny mixed borders or as a large informal screen or hedge. The short floral stem can be cut and placed in water to enjoy the open flower for one day.
