Cranberry Hibiscus Hibiscus acetosella

Cranberry hibiscus is a tender perennial sub-shrub in the Malvaceae (mallow) family native to tropical eastern Africa. While flowers might be the first thought when you hear the name hibiscus, the deep purple red foliage is what makes this shrub stand out.

Rapidly growing to a height of 3 to 5 feet and 2 1/2 feet wide, cranberry hibiscus requires full sun and will perform best in average to moist but not wet soil. Its growth habit is somewhat sparse and leggy, so plant densely or pinch back tips to encourage fuller growth. Hibiscus can be pruned, but keep in mind that flowers will appear on new growth. Cut it back to the ground before winter. While it may not survive year-round outdoors, it can be overwintered as a houseplant. It grows easily from seed or can be propagated from stem cuttings taken in the fall and rooted in water or soil.

Plant in a cottage garden, mass plant in the back of a border, use as an annual specimen plant, in containers, or use as a seasonal hedge. Some pinching back may be necessary if grown in a container to maintain bushiness and size. Intersperse this plant with others that have lime green or silver leaves, or with ornamental grasses for some contrast and interest in the landscape. 

Insects, Diseases, and Other Plant Problems:  No serious problems.
