Swamp Hibiscus Plant Info: How To Grow Rose Mallow Hibiscus

By: Mary H. Dyer, Credentialed Garden Writer

Swamp mallow (Hibiscus moscheutos), also known as rose mallow hibiscus or swamp hibiscus, is a shrubby, moisture loving plant in the hibiscus family that provides big, showy flowers from mid-summer to autumn. The plant performs well along pond edges or other damp areas. This stunning, low-maintenance plant is available in a range of colors, including pink, peach, white, red, lavender, and bi-color varieties.

How to Grow Rose Mallow

The easiest way to grow rose mallow is to purchase a plant at a garden center or nursery. However, growing rose mallow by seed isn’t difficult. Start seeds indoors eight to 10 weeks before the last frost in your area or plant seeds directly in the garden after the last killing frost in spring.

Rose mallow benefits from rich soil amended with at least 2 or 3 inches (5 to 7.5 cm.) of compost, manure, or other organic material. Locate the plant in full sunlight. Although rose mallow tolerates partial shade, too much shade may result in leggy plants that are more susceptible to insect infestations.

Allow at least 36 inches (91.5 cm.) of growing space between each plant. Crowding the plant inhibits air circulation which may result in leaf spots, rust, or other diseases.

Swamp Hibiscus Care

Swamp hibiscus plants are water-loving plants that will stop blooming in dry soil. However, the plant, which dies and enters a dormant period in winter, shouldn’t be watered until it displays new growth in spring. Once the plant is actively growing, it needs a deep watering two or three times per week during warm weather.

Water is especially important during the first growing season, but the plant should always be watered immediately if it shows signs of wilt.

Feed rose mallow every six to eight weeks during the growing season, using a balanced, water-soluble plant fertilizer. Alternatively, use a slow-release fertilizer after the plant breaks dormancy in spring.

Spread 2 or 3 inches (5 to 7.5 cm.) of mulch around the plant to keep the roots moist and cool, and to keep weeds in check.

Spray swamp mallow with insecticidal soap spray if the plant is damaged by pests such as aphids, whiteflies, or scale.

Hardy Hibiscus Plant Profile

The Spruce / Letícia Almeida

If you crave a taste of the tropics in the North, try growing hardy hibiscus plants. They often produce flowers of a size rare for plants that can survive cold winters. Perennials that serve as excellent foundation planting, hibiscus are a colorful addition to a garden. They can be planted in spring or fall (as long as there is no risk of frost) and grow quickly. The showy flowers—often referred to as "dinner plate hibiscus"—feature tissue-thin, ruffled petals in blues, pinks, reds, and whites. However, they're better suited to the landscape than to being cut and placed in a vase, where they'll last only a day or so.

Eleven Easy Tips for Growing Hardy Perennial Hibiscus

Hardy Hibiscus! Mighty Mallow!

Although there are hundreds of hibiscus species, only a few dozen are cold hardy here in the southern US. Here at Plant Delights Nursery, we grow several species of hardy hibiscus plants that fall into two groups: 1) the giant-flowered, dieback species known as Scarlet Rose Mallow or Swamp Rose Mallow and 2) the woody species known as Rose of Sharon or Confederate Rose. Both groups are super easy to grow and provide many weeks of beautiful summer or fall flowers.

Below are the top growing tips for group 1: Rose Mallow and Swamp Rose Mallow. This group includes the species Hibiscus moscheutos, H. coccineus, H. aculeatus, H. dasycalyx, H. lasiocarpos, H. laevis, and H. grandiflorus. Stay tuned for a separate growing guide for Rose of Sharon.

Tip #1 The Importance of Hibiscus Cultivar Selection


Hibiscus 'Midnight Marvel' PP 24,079

Newer hybrids of hardy hibiscus plants (since the 1950's) tend to have fuller petals, larger flowers and a shorter, more garden friendly height. Great cultivars include 'Peppermint Flare', a white with pink splotches, 'Fantasia', a nice pink, and 'Fireball', a great red. All are shorter than wild type plants. Many popular breeding breakthroughs in this group (i.e., purple foliage) were made by the late Fleming brothers of Nebraska and we are pleased to offer many Fleming brother's introductions. We also carry the latest generation of modern hybrids from the breeders at Walter's Gardens. For large gardens, the 8' tall wild type species (i.e., Hibiscus coccineus) look great and their narrow petals are quite beautiful and exotic.

Tip #2 Sun


Hibiscus coccineus

All hardy hibiscus plants prefer full sun or maybe just a little afternoon shade. More sun = more flowers.

Tip #3 Temperature


Hibiscus 'Summer Storm' PP 20,443

Most Hibiscus plants are cold hardy down to zone 4, 5 or 6 depending on the parentage of the cultivar. Click here for a complete list of hardy hibiscus cultivars at Plant Delights to see the hardiness zone range for each.

Tip #4 Soil


Hibiscus mutabilis 'Flora Plena'

Rose Mallow and Swamp Mallow tolerate a wide range of soil types, sand or clay, acid or sweet. Perennial Hibiscus plants are mostly native to swampy areas and can be grown in wet soil along the edge of a pond, but they are also very adaptable and grow well in standard garden conditions.

Tip #5 Pruning


Hibiscus 'Fireball' PP 13,631

Rose Mallows and Swamp Mallows need little pruning. Leave the dead stems and seed pods until late winter (unless re-seeding is a problem in your garden) as the stems look nice during the winter when covered in frost and snow and the seeds are a winter food source for birds. In spring prune the old stems to the ground as the new shoots emerge. Some folks like to tip prune the new stems in early summer to promote a bushier habit, but Hibiscus will grow just fine without this treatment.

Tip #6 Fertilizer


Hibiscus coccineus 'Swamp Angel'

Rose Mallows and Swamp Mallows respond well to organic fertilizer. A fresh topping of compost once a year will suffice.

Tip #7 Watering


Hibiscus 'Angelique' PP 13,734

Keep perennial Hibiscus plants well-watered as they do not tolerate drought. They may drop their flower buds or become susceptible to insects and disease if they are water stressed.

Tip #8 Propagation


Hibiscus 'Copper Queen' PP 23,941

Hardy Hibiscus plants can be divided in spring. Or you can collect and plant the seed. just note that the seedlings may not resemble the parents. Stem cuttings will root easily if taken prior to flowering.

Tip #9 Dealing with problems


Hibiscus grandiflorus

Rose Mallow and Swamp rose hibiscus may be dined upon by aphids, whiteflies and Japanese beetles. Pest problems are worse if the plant is stressed but pests are easy to control with common organic insect controls. Just be careful not to kill off butterflies or other good insects that may be nearby. Fungus problems can be controlled by maintaining good air circulation around the plant, by keeping mulch from touching the stems, and by removing diseased leaves and discarding them in the trash.

Tip #10 Cut flowers


Hibiscus makinoi

The giant crepe-papery flowers of the Rose Mallow and Swamp Mallow hibiscus look great but last only a short time in a vase so they aren't a good cut flower plant. But the dried seed pods are exotic-looking and will last a long time in an arrangement.

Tip #11 Culinary uses


Hibiscus 'Turn of the Century'

As a general rule, all perennial hibiscus species are edible. young leaves and flowers have a mild flavor. The leaves, roots, and shoots are filled with a gooey substance (they are mallows - okra relatives) that is used to thicken soups and can even be whipped into a merengue. As the leaves, roots, and stems mature, they become fibrous and unpleasant. Seeds can be pressed to release oil useful in cooking. Try the leaves raw in a salad or boiled like greens, or chopped up and added to soups.


How to Prune a Swamp Hibiscus

The brilliant red, show-stopping blooms of the swamp hibiscus (Hibiscus coccineus) can turn a wet area of your yard or garden from a problem to a focal point. The deciduous shrub produces five-petaled scarlet flowers, each 3 to 5 inches across, from late spring until stopped by frost in U.S. Department of Agriculture plant hardiness zones 6 through 11. While the plant is easy care, pruning your swamp hibiscus can make a good thing even better.

Pinch off the growing tips, the buds at the end of each straight stem on your swamp hibiscus in late spring to early summer, when the plant is about 2 feet tall. Swamp mallow grows up to 7 feet tall and about 3 feet wide, narrower than many other hibiscus species. Pinching off the tips encourages the upright stems to branch out for a fuller plant that will have more blossoms.

Remove flowers as they fade before they produce seed pods to keep the plant blooming strongly. Each flower lasts only one day.

Cut back all the stems with pruning shears or bypass pruners after the first flush of bloom has passed in late summer for optimal bloom through fall.

Prune dead stems back to within a few inches of the ground in late winter or early spring before new growth emerges. Swamp hibiscus dies back to the ground in winter, even in moderate climates. Cutting it back too early, however, can lead to rot as water can collect in pruning wounds over the wet winter.

  • Swamp hibiscus grows well in normal well-drained garden soil with additional water.
  • Swamp hibiscus is also called scarlet hibiscus and star of Texas.

It looks very tropical, but it's not. Have it planted in a container. Forgot and left it out during a hard freeze for several days. Just knew that it was probably dead. It is coming back up from the roots. So far, it's a winner!!

Very easy plant to grow. Last year I had 2 plants in normal draining pots. This year I transplanted them to 5 gallon buckets without drainage holes. I buried the pots in the ground. Now I can keep them wet constantly. One is almost 7' in May. Plenty of buds getting ready. I didn't have a pond to put them in so this is the next best thing.

I love this plant! I had white variety and red variety seeds I had collected and scattered the seed randomly in my flower bed. The first year they did not flower, but I noticed the stems of the plant revealed the color of the flower - the red flowered plants had reddish stems and the white flowered plants had white stems! Has anyone else noticed this? I thought that was pretty cool!

It's definitely a "WOW." It's a great addition to any 'tropical themed' design for sure. I plant ours with a variety of canna lilies to achieve this affect. Ours are in a clay soil near the porch roof line - the water runoff was plenty (even with a pretty long drought) to get 5-6ft tall plants from seed the first year that had multiple blooms the size of my face. They were a stunning scarlet and the hummingbirds agreed. Very easy from seed, those left 1 gal pots grew to 3 ft but did not bloom this year, This may have been because they did receive less water than those that were planted out. I cannot wait to see how much bigger they are next year and in the years coming. If you've got a big space to fill- this is a great choice!

I planted the seeds in several containers in mid-March. They all came up. I have now transferred the small seedlings from their cup containers to larger pots. I used a mixture of mulch, topsoil and a small amount of blood meal mixed into the soil and mulch.They seem to be taking off in the larger pots.

In my experience, the red variety is more of an orange color. However, in many of these DG images the flowers appear to be magenta. Does hibiscus coccineus actually come in a magenta color or even a true, non-orange-ish red? I have both the "red" and white varieties which I grew easily from seeds.

They are in constant water, full sun and have reached about 9 feet with plenty of side shoots producing great flowers.

I normally cut back half the stems when they are about 2 feet high, otherwise they look rather ragged. This allows about 5 stems to reach full height and the others bush out below them to fill in the space.

I also leave only 2 buds on each branch so the flowers will be bigger.I have learned however that you have to be carefull not to overwater these as the leaves will yellow and start to fall as will the buds.

Planted in fall last year (nursery specimen). New growth did not appear until early May 2003. Plant is approx. 6 feet tall and 3 feet wide with several "stalks" emerging from base. Buds form in clusters at the top of each. Leaves are similar to a hand that are deep green with 6-7 seraded fingers. Does well in partial shade to full sun. A wonderful specimen to add a different "flavor" to your flower bed or garden.

Another common name is Swamp Hibiscus, I thought by the name it would need a shady damp place. I planted one in shade and one with part sun - the one in more sun had many more blooms and grows more rapidly. I gave my neighbor a small one and his was planted in full sun, it was full of blooms when mine only had one or tow blooms at a time.

With its love of moisture, this plant is a great addition to a water garden, which is where I have mine. The blossoms are large (about 8 inches across) and a beautiful scarlet color. It is supposed to attract hummingbirds. The plant goes dormant in the winter. The old stems can be cut off when new growth appears in spring. There is an albino form of this plant.

I have had this plant for two years now and each year it is more beautifl than the last. It loves to be packed with other plants. I take the seeds from the pods when the pods begin to open and have started several plants that way. It seems like the plant needs a couple years to bloom. I planted two seeds last year and they have come up, but very slow. The parent plant is almost 5 feet tall now, while the new plants are only 2 feet tall. I will try to keep you abreast of the growth. I live on the coast in NC.

Hibiscus coccineus is a hardy perennial in zones 6-11, and is native to the USA.

This plant has many common names including Texas Star, Scarlet Hibiscus and Swamp Mallow


1.  Hibiscus moscheutos L. ssp. moscheutos N

swamp rose-mallow. Hibiscus incanus Wendl. f. H. moscheutos L. ssp. incanus (Wendl. f.) Ahles H. moscheutos L. ssp. palustris (L.) Clausen H. oculiroseus Britt. H. palustris L. • CT, MA, NH, RI. Borders of saline and brackish marshes. Hibiscus moscheutos ssp. palustris, a taxon said to be characterized by pink corollas and three-lobed leaf blades, has been traditionally recognized apart from H. moscheutos ssp. moscheutos, said to be characterized by white corollas with a red central region and unlobed leaf blades. Flower color and leaf blade morphology has been shown to intergrade and not reliably distinguish taxa (Blanchard 1976). Therefore, H. moscheutos ssp. palustris is placed in synonymy.
