Plant Common Name

General Description

The tropical hibiscus 'Amour' has large, thin, flowers that are pink and white. The wavy petals are are white but have have edges in varying shades of pink and pale pink. Hibiscus rosa-sinensis is an evergreen shrub that originates from China, and 'Amour' is a hybrid derived from two cultivated varieties. This medium sized tropical hibiscus is vigorous and blooms modestly over an extended period of time.

The glossy leaves of 'Amour' are light to medium green and oval to somewhat wedge-shaped. Its flowers are large, radial and flattened, and may curve gracefully backward, even rolling in hot weather. In the small burgundy center is a pink floral tube with a bottlebrush of bright yellow anthers and red stigmas, adding additional floral delight and contrast.

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 cultivar can be grown in sunny mixed borders, along foundations or in large containers that can be moved indoors to overwinter if needed. The short floral stem petioles can be cut and placed in water to enjoy the open flower for one day.
