Botanical Name

Plant Common Name
Kinchen's Yellow, Queen-of-the-tropics., Tropical Hibiscus
General Description
The tropical hibiscus 'Kinchen's Yellow' creates among the most beautiful of yellow flowers in the plant kingdom. Each rounded petal is perfectly ruffled and overlaps the next, having a crepe-paper texture. Hibiscus rosa-sinensis is an evergreen shrub that originates from China, and 'Kinchen's Yellow' is a hybrid derived from two cultivated varieties. This tropical hibiscus is vigorous and blooms well over an extended period of time.
The broad, glossy leaves of 'Kinchen's Yellow' are deep green and oval-shaped. Its flowers are large, radial and broad. In the small white center of each is a stubby white floral column lined with a bottlebrush of bright yellow anthers and stigmas.
Tropical hibiscus is heat tolerant, excelling in full to partial sun and acidic to neutral, fertile soil with good drainage. Very poor and highly 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, modestly 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 day.
