Hibiscus is a genus of sun-loving shrubs and small trees with tropical-looking showy flowers in shades such as pink, bright red, pastel orange, white, and yellow. Hibiscus flowers are easily recognizable with their funnel shape, large papery petals, and contrasting colorful centers. Individual hibiscus flowers may only bloom for a day or two, but the bushes produce blossoms throughout the summer.
Choosing the right hibiscus for your front or backyard depends on your climate. Tropical hibiscus plants bloom throughout the year but only grow in USDA zones 9 through 12. Hardy hibiscus perennial shrubs produce huge, showy flowers and thrive in USDA zones 5 through 11.
Some tropical hibiscus varieties grow as annuals in temperate regions. Or you can grow the flowering heat-loving shrubs in containers and bring them indoors when the temperature dips below 50°F (10°C).
One thing in common with hardy and tropical hibiscus plants is their spectacular flowers in many different colors. Some of the most attractive hibiscus flowers have multi-colored petals.
To care for all hibiscus varieties, grow the garden landscaping shrubs in full sun, well-draining soil, and keep the ground moist.
There are many species of hibiscus and hundreds of cultivars. This article looks at some of the most common tropical and hardy hibiscus shrubs. The tropical hibiscus cultivars are generally Chinese hibiscus (Hibiscus rosa-sinensis) or Hawaiian hibiscus (Hibiscus arnottianus). Hardy hibiscus varieties are either rose of Sharon (Hibiscus syriacus), rose mallow (Hibiscus moscheutos) and scarlet rose mallow (Hibiscus coccineus).

Hibiscus Flowers
Tropical hibiscus flowers come in a wide variety of colors and can be single or double blooms
Hibiscus flowers are trumpet-shaped, showy blooms that often have brightly-colored ruffled petals. The funnel-like flowers can grow between 3â and 10â (7.5 â 25 cm) across. A feature of most hibiscus flowers is the long colorful protruding stamens emerging from the flowerâs center.
Flowers on hibiscus plants only last for one to three days. However, hibiscus flowering shrubs and trees produce blossoms throughout the growing season.
Hardy hibiscus cultivars bloom from mid-summer until fall. On the other hand, tropical hibiscus varieties can bloom throughout the year, right through mild winters.
Hardy hibiscus flowers are single blooms in colors of white, pink, purple or red and can be very large
Generally, flowers on hardy hibiscus shrubs are larger than the tropical varieties. But all hibiscus shrubs and small potted trees are known for their showy, tropical blooms in dazzling array of colors.
