There are twenty-two species of Hibiscuses that grow wild in the Continental United States and considered as native hibiscus. Both Alaska and Nevada have no native hibiscus while Florida and Texas have the highest number of species. Most common native species is Hibiscus moscheutos which is found in 35 states.
Characteristics of Native Hibiscus:
- They can be perennial or annual
- evergreen or deciduous
- can be found in swamps, marshes in the east coast, or dry rocky areas in the west coast.

How to grow native hibiscus?
There are over 300 species or types of Hibiscus plants. But not all of them are native to the United States. Swamp hibiscus (H. coccineus) and rose mallow (H. moscheutos) are native American plants. Below we have discussed how to grow a native hibiscus – Hibiscus moscheutos.
This plant grows well in U.S department of Agriculture plant hardiness zones 5 through 10. Hardiness zones 5 through 10 include city like Atlanta, Baltimore, Boston, Buffalo, Chicago. Dallas, Denver. Plant hardiness zone map is the standard by gardeners and growers can determine which plants are most likely to thrive at a location.
Hibiscus grows well in slightly acidic soil that has a pH between 6.5 and 6.8. before planting, determine your soil pH by testing it. In order to achieve optimum pH in soil, you can add amendments either to increase pH or decrease pH. Adding Pennington® Fast Acting Lime will increase pH while applying soil sulfur will decrease it. If you want to grow hibiscus in containers, use potting soil that drains well and that’s designed for acidic plants
Prior to planting, enrich the soil by amending it with homemade or bagged compost and Pennington® Earthworm Castings 1.5-0-0. According to a study conducted by the American Society for Horticultural Science found that hibiscus grown with worm compost grew bigger and had better blooms.
Enhance soil fertility and encourage profuse hibiscus blooms by adding Lilly Miller Lawn & Garden All Purpose Plant Food to the planting area.
Abundance of light
The best place to plant a hibiscus plant is a location that gets direct sunlight for five to six hours a day. They also grow in partial sunlight. For optimal growth, the plant requires full sun as much as possible.
Fertilizers to apply

In order to make sure that hibiscus receives essential nutrients, also fertilize monthly with Alaska® Pure Kelp Plant Food 0.13-0-0.60.
Flower & Foliage
Hibiscus moscheutos has showy, dinner-plate-sized, , hollyhock-like flowers. Each flower measures 4-6” diameter that has five overlapping white, creamy white or pink petals with reddish-purple to dark crimson bases which form a sharply contrasting central eye.

But new flowers bloom each day in rapid succession between July o September. At height of blooming period, a large plant can produce up to 20 or more flowers a day.
The leaves of the Hibiscus moscheutos are alternate, broad-ovate to lanceolate (3-8” long) with toothed margins which are green above and white-hairy beneath. The leaves have 3-5 shallow lobes.
Care and Maintenance
Hibiscus tree care is not extensive. At the beginning of the planting, it requires regular watering, fertilizing. But when it is established, it will bloom in its own way. Below are a few essential maintenance procedures:
Keep the soil surrounding the plant moist but not soggy. In the first week of planting. Water daily. In the second week, water in every two days. After the second week, water twice a week. But if the weather becomes hot and dry, water every other day. Stop watering the foliage when irrigating hibiscus because wet foliage can lead to foliar diseases, such as mildew.
Prune to boost blooming
The longevity of hibiscus blooms only last a day before falling off the day. Remove spent blooms to keep the plant tidy. For plants that you grow outdoors in a mild climate, prune the shrub back by one-third in late winter or early spring. Remove crossing and dead branches.
Diseases & Pests
Hibiscus moscheutos is vulnerable to several pests and diseases. Insect pest can damage the plant in several ways. The damages include premature dropping of flowers, failure to bloom and thrive overall, holes in leaves and petals, and a gooey substance on plants and nearby surfaces.
Check the plant periodically for signs of pests and pest damage. Minor infestations can be removed with a strong spray of water. However, for recurring and severe infestations, you need powerful insect killer.
The plant can also be affected by leaf diseases including gray mold and downy and powdery mildew. Such disorders have symptoms white, gray or yellow splotches on leaves and can lead to moldy buds that fall off before blooming. If such symptoms appear, treat the plant with the right fungicide
Growing native hibiscus does not require a lot of effort to care for. It only needs certain conditions in order to thrive. Below are a few recommendations:
- Hibiscus blooms well in slightly acidic soil. If the soil of your garden is not acidic, make it acidic by adding peat moss.

- Plant it where it is exposed to direct sunlight.
- The plant flourishes most between 60 degrees Fahrenheit and 90 degrees Fahrenheit. Once the temperature drops to 32 degrees Fahrenheit mark, bring the plant indoors so that cold weather does not cause damage to the plant.
- Prune the plant to stimulate the budding process. Pruning also helps the plant thrive throughout the summer months.
The plant grows well in hardy zone 4. Alaska belongs to this zone.

This plant grows quickly. It can be pruned heavily in the early spring to encourage larger blossoms. This is a self-seeding gardening plant. It means the plant drop their pods, capsules or seeds at the end of the season. The seeds only require the soil they fall onto and utilizes natural seasonal changes to germinate and grow.

But hibiscus is not shrub. Plant hibiscus tree along the sides or the back of a house where a tall plant is needed.

Because if pruning is not done, there are many hibiscus varieties that grow too large for the average house. But pruning does not decrease bloom since hibiscus flowers on new wood.
