- Description
-
Chinese hibiscus is a large shrub that is a member of the Malvaceae (mallow) family. It is native to Asia. It grows 4 to 10 feet high and 5 to 8 feet wide, so consider its space requirements when determining its planting location. This is a tropical, evergreen plant known for its bold flowers that can be up to 6 inches across with a showy central tube. The genus name Hibiscus is Latin for mallow and the species names rosa sinensis are Latin for rose and Chinese.
Plant in a location with full sun to partial shade and in rich moist soil with good drainage. The roots should be kept moist. Chinese hibiscus appreciates high humidity and protection from wind and frost, but it is resistant to browsing by deer.
When planting, set each plant 12 to 24 feet apart outdoors or indoors in a large container in a location that receives bright light. Chinese hibiscus has a medium growth rate and requires some maintenance and care. Prune back by about one half the height in early spring to encourage a compact growth habit. Keep in mind that flowers will bloom on new growth. Chinese hibiscus is sensitive to environmental changes so moving the plant can cause leaf and bud drops. Propagation occurs through stem cutting.
Plant in your butterfly garden or naturalized area. It can also be grown in a container and as a houseplant. Plant multiples for use as a screen or hedge, or plant singularly as an accent plant. Its large funnel-shaped flowers bloom in summer and are an attractant for specialized bees and pollinators.
