The hollyock is related to the hibiscus, though not a true hibiscus; however, this biennial plant is grouped with hibiscus species for its close resemblance.

Confederate roses Hibiscus mutabilis are large perennial shrubs that display double pink and white blooms, and often grow from 8 to 15 feet tall, according to the Clemson University Extension.

Water plants deeply and thoroughly, but allow some time between drenchings on established plants. Newly planted hibiscus will need more frequent watering, like other newly planted perennials.

Some species and varieties will actually tolerate permanently damp soil and flooding. Tall hibiscus should be sited where they are not exposed to strong winds to avoid breaking of the long stems.

Stems that break can be shortened and new side shoots will grow and produce more blooms. To encourage rebloom, either remove old flowers before they form seedheads or prune plants back by one third after a flush of bloom is finished. Perennial hibiscus will freeze back to the ground each winter in all but the warmest parts of South Carolina.

Old stems can then be cut back to the ground. New shoots emerge by mid spring. Propagation: Hibiscus are easy to propagate by several methods, making them a common passalong plant, especially since some popular types such as Confederate Rose can be difficult to find in stores. Cuttings: Cuttings can be rooted at anytime that new growth is available, although rooting is usually quickest in spring.

Start with pencil thick, five to six inch long cuttings of firm new growth. Strip off lower leaves and insert the cutting in a mix of three parts sand and one part peat.

Roots should form within four to five weeks. Once roots are formed plants can be moved into a larger container or transplanted to a permanent location. Seeds: Seed can be sown indoors 12 weeks before the last spring frost. Soak seeds in very warm water for one hour before sowing. Seed can also be sown in place outdoors after the last expected frost date or fresh seed can be sown in fall. Collect seed for fall sowing once the papery seed capsules brown and start to split.

Plants often bloom from seed in their first year and will often self seed in suitable soil conditions. Division: Perennial hibiscus can be divided in spring. Be careful working around the soft new shoots. They do not usually tolerate fall division or transplanting. Problems: Leaf spots may be caused by several fungi. In most cases, cleaning up plant debris and removing infected leaves will provide adequate control. Southern stem blight may occur on hibiscus.

To help prevent southern blight, keep mulch from touching the stems. The six to eight inch wide flowers are brilliant red, with petals more separated than those of other hibiscus, giving the blossom a star shaped look. Individual flowers last only a day but new blooms open throughout summer and fall. The leaves are deeply divided into narrow, toothed, finger-like lobes.

This plant is often passed along from gardener to gardener. Established plants grow to seven feet each growing season. Plants die back to ground level in winter and resprout in spring. Scarlet swamp hibiscus prefers full sun and moist soil. Naturally occurring in swamps, marshes and ditches, this hibiscus will even tolerate some flooding, although it will also thrive in ordinary garden soil.

Rose Mallow Hibiscus moscheutos : Rose mallow is native to marshy areas throughout the southeast. It has been extensively bred and is the parent of a number of popular hibiscus hybrids, often referred to as dinner plate hibiscus due to the large size of their flowers. The large, fast-growing plants bloom from August to October.

Individual flowers last only a day, but each plant may flaunt several 10 to 12 inch wide flowers at once. Grow rose mallows in rich, well-drained soil with full sun for best results. At the end of autumn, cut old stems back to three to six inches above ground level. Propagation is possible from seed, tip cuttings and root division. Rose mallows will flower from seed the first year if started very early in spring. Favorite cultivars may be rooted from cuttings during the growing season.

Rose Mallow is highly variable and the parent to many hybrids. The flowers are pink with a red center. Because the petals are deeper colored on one side, the blossoms have a pinwheel effect. Plants grow up to six to eight feet tall.
