General Description

The tropical hibiscus 'Sunshower' dazzles with scarlet blossoms with mottled stripes of yellow. Each round and ruffled, crinkly, slightly overlapping petal opens wide and often recurves downward. There are streaks, stripes or blotches of bright yellow at the petal outer edges, with hints of orange-red. Hibiscus rosa-sinensis is an evergreen shrub that originates from China, and 'Sunshower' is a hybrid derived from two cultivated varieties. This tropical hibiscus is vigorous and blooms well over an extended period of time.

The glossy leaves of 'Sunshower' are bright green or yellow-green and broadly oval to heart-shaped. The flowers are large, radial and broad and have much more amounts of yellow when they develop in sunshine (on non-cloudy days), and more uniformly red during overcast weather. In the dark pinkish red center there is a long red floral column with a bottlebrush of yellow stamens and dark red stigmas.

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, round-habit cultivar can be grown in sunny mixed borders or foundation beds, as an informal hedge or in large containers that can be moved indoors to overwinter if needed. The short floral stem can be cut and placed in water to enjoy the open flower for one day.
