Botanical Name

HIBISCUS rosa-sinensis 'Crown of Bohemia'

Plant Common Name

Crown of Bohemia Tropical Hibiscus, Queen-of-the-tropics., Tropical Hibiscus

General Description

The tropical hibiscus 'Crown of Bohemia' dazzles with double golden yellow flowers. Each ruffled petal is yellow to golden in color, with flushes of orange possible, sometimes with a pronounced, but small, cherry red or dark rusty red base. Hibiscus rosa-sinensis is an evergreen shrub that originates from China, and 'Crown of Bohemia' is a hybrid derived from two cultivated varieties. This tropical hibiscus is vigorous and blooms well over an extended period of time.

The broad semi-glossy leaves of 'Crown of Bohemia' are dark green and oval-shaped with small teeth. Its flowers are large, irregular, and ball-like. Interestingly, during cooler weather the petals are often more orange-yellow. The floral column that is obvious in hibiscus is reduced in this variety and hidden among the many contorted petals.

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, in spacious foundation beds 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 to two days.
