Two very different plants share the name hibiscus: tropical hibiscus (Hibiscus rosa-sinensis), an evergreen shrub that needs frost protection, and hardy hibiscus (Hibiscus moscheutos), a perennial that dies back each winter and returns. This guide covers both and keeps them apart. Our sources give full sun to partial shade for both, with full sun producing more bloom. The ASPCA hibiscus page says the plant is non-toxic to dogs, cats and horses.

Which hibiscus do you have?

Tropical hibiscus

Hibiscus rosa-sinensis is an evergreen with flowers up to 6 inches across (NC State). It grows 4 to 10 feet tall and 5 to 8 feet wide, needs protection from frost and wind, and is sensitive to cold weather: UF/IFAS says the slightest cold wave can make lower leaves yellow and drop.

Hardy hibiscus

Hibiscus moscheutos is a mid-summer blooming perennial with large, round flowers in pink, red or white, 6 to 8 inches across (NC State, Clemson). It grows 2 to 6 feet tall and 2 to 5 feet wide and is heat and humidity tolerant.

Light

For tropical hibiscus, NC State says full sun to partial shade, and that in full sun the plant has better bloom production and is more disease resistant. For hardy hibiscus, NC State says full to partial sun and recommends a location with full sun to partial shade, with full sun giving better bloom.

Soil and water

For tropical hibiscus, NC State says the roots should be kept moist. For hardy hibiscus, NC State says wet to constantly moist loam with organic matter and slightly acidic soil.

Pruning

The cuts differ by type. Our hibiscus pruning guide sets tropical and hardy side by side.

  1. Tropical: prune in early spring. NC State says to cut it back by about half in early spring, and that it blooms on new growth.
  2. Hardy: pinch and deadhead. NC State says to pinch tips and deadhead during the season.
  3. Hardy: cut back in fall. NC State says to cut the stems nearly to ground level in the fall.

Bloom time

Tropical hibiscus has a long season, nearly year-round in South Florida (UF/IFAS). Hardy hibiscus blooms from midsummer to early fall, with each plant’s bloom lasting about a month.

Growing in a container

For tropical hibiscus, NC State says it can be grown in a container with bright light indoors. NC State also says it needs protection from frost and wind. Hardy hibiscus grows as a perennial.

Cultivars

Clemson names ‘Luna White’ as a hardy cultivar, about 3 feet tall and wide.

Pets

The ASPCA hibiscus page, which lists Rose of Sharon and Rose of China, says non-toxic to dogs, cats and horses. This is the genus page rather than a species-by-species statement.

Gardenia is another flowering shrub for containers. Bougainvillea and mandevilla are sun-loving climbers for pots, and the tropical flowers collection compares them all.
