What Kind of Hibiscus Comes Back Every Year?

Hibiscus brings that lush, tropical zest we associate with sunny summertime days. With perennial selections, we can experience the blooms year after year with easy care. Rose mallow (native species and their cultivars) have papery disk blooms among unique foliage. Rose of Sharon, with ruffly flowers, lends vertical interest. Explore lasting selections of hardy hibiscus with gardening expert Katherine Rowe.

This hibiscus plant features large, deeply lobed dark burgundy leaves and a striking, oversized flower with soft pink petals, a deep red center, and delicate ruffled edges.

Tropical hibiscus, the sun-loving accents that bring flair to summertime displays, grow year-round in warm climates and as tropical annuals in colder regions. Cold-hardy hibiscus have a more versatile range, generally perennializing in USDA zones 4 or 5 through 9 for years of high color.

Hibiscus that come back every year include rose mallow and rose of Sharon. While different species, both fall into the catchall moniker “hardy hibiscus,” though it most often refers to rose mallow.

Rose mallow brings the tropical look to the perennial garden with dinner-plate-sized flowers. Unlike tender tropical hibiscus, hardy hybrids stem from North American native mallows (H. moscheutos, H. laevis, and H. coccineus), with adaptability, durability, cold hardiness, and unique color blends. 

Rose of Sharon (Hibiscus syriacus) is a vigorous shrub with characteristically showy hibiscus blooms. It’s larger in stature than the perennial mallows, with somewhat smaller flowers. Some varieties produce abundant seed pods that readily reseed and become invasive. Sterile or seedless cultivars are available to reduce the spread (although there is discussion about sterile cultivars of invasive species and their impacts on the surrounding ecology).

Rose Mallow Overview

This plant showcases sturdy green stems with broad, dark green leaves and large, velvety deep red flowers with ruffled petals and a dark maroon center.
Durable perennials flourish in sunlight, showcasing bright summer flowers.

Hardy hibiscus are low-maintenance, easy-care growers. Rose mallows are hardy in USDA zones 4 or 5 through 9. They show the best flowering and stem strength in full sun, with at least six hours of sunlight daily. They also grow in partial shade.

Mallows prefer organically rich soils but adapt to various types given regular water. The moisture-loving plants grow naturally in wet areas. They withstand short dry spells, but in prolonged drought, stress leads to susceptibility to insect damage from Japanese beetles and hibiscus sawflies.

Give them a heavy layer of mulch for moisture retention and overwintering. In spring, new growth is slow to appear, but once it does, it emerges quickly for summer foliage and flowering.

The robust perennials bloom in the heat of summer through early fall. Each flower opens only for a day, but with abundant buds, the flowering is continual.

Showcase rose mallow in the perennial border, rain garden, native planting, bog, and container display. The bright petals and prominent stamens attract pollinators.

Native Species

While easily recognized by their similar flowers, North American native mallows are diverse in color, form, and habitat. The most popular are H. moscheutos and H. coccineus, adaptable selections with showy blooms.

Swamp

This plant showcases tall, slender stems with heart-shaped green leaves and large, vibrant white-to-pale pink flowers, each with a bold red center and delicate, ruffled petals covered in water droplets.
This vigorous native features stunning blooms from July to September.

This shrub offers vibrant blooms and striking vertical interest.

Rose of Sharon (also called althea) brings vertical interest and a carefree habit with shrubs that reach eight to twelve feet tall. The growing conditions are largely similar among the genus, and they’re usually hardy in zones 5-9. Like their mallow relatives, they grow best in full sun to partial shade with moist, well-draining soils. The adaptable growers tolerate heat, humidity, and coastal and urban situations.

Rose of Sharon is indigenous to India and China and began growing in the U.S. in the 1700s for its ornamental qualities. It begins blooming in July, and continues until frost with hollyhock-like flowers. Its showy petals in pink, white, and purple often have a dark central eye, and the single or double blooms have ruffly appeal. Attractive foliage is usually maple or heart-shaped on vase-shaped, upright, and columnar forms.

The flowering shrub makes a visual impact in groups and hedges, as foundation accents, and border specimens. It takes pruning well and trains as an espalier.

Many rose of Sharon cultivars are available in varying sizes, forms, and colors. They offer exciting twists on the vintage favorite and tend to reseed less vigorously.

‘Lil’ Kim’

With compact stems and vibrant green leaves, this variety displays charming, small flowers in white with dark pink centers.
This petite variety blooms generously with white flowers throughout summer.
