Hibiscus is a popular plant among gardeners around the world, due to its beautiful flowers and its many uses. There are many different varieties of this plant and each one has its own special qualities. However, they also do share some common characteristics: they produce beautiful blooms and are available in a wide range of colors including double or single in form.
If you’re having trouble deciding which type of hibiscus to grow in your garden, we’ve got you covered. In this article, we’ve put together a list of the most popular types of hibiscuses planted in gardens around the world. Let’s take a look.
Native hibiscus is a fast-growing, herbaceous plant that can grow to a height of 4 to 15 ft and a width of 4 to 8 ft, depending on the species. They grow naturally in wetlands, but they can also thrive in dry areas and bloom well in full to partial sunlight.
As most of these plants grow quite large, they need enough room and should be spaced far apart from each other when planted in rows. They can be propagated by seeds or stem cuttings.
Here are some examples of native hibiscus plants:
1. Blue Hibiscus (Alyogyne huegeliii)
Blue hibiscus is an evergreen shrub belonging to the Malvaceous family which is a native to Western Australia. This plant prefers the coastal shrubland’s sands and has beautiful, trumpet-shaped blooms that are lilac-blue to mauve purple in color. It’s a sun-loving plant that is ideal for gardens, containers, and shrub or wall-side borders.
Blue hibiscus doesn’t require a lot of watering and fertilizing. It’s a low-maintenance plant with a lower risk of getting pest infestations and diseases. The foliage consists of medium-sized dark green leaves which are 3-4 lobed deeply. It belongs to the USDA zones of hardiness 5-8.
2. Dwarf Hibiscus (Hibiscus divaricatus)
With its dense, large green foliage this plant usually produces bright yellow blooms but there is also a rare white and pink species. It’s a drought-tolerant plant that grows well in the full sun and well-drained soil. Dwarf hibiscus is native to Queensland and Western Australia.
This plant blooms in spring and summer, growing up to about 5 meters in height, and has smooth stems with large leaves. It grows well in USDA zones 5 through 9 at a medium growth rate.
3. Native Rosella (Hibiscus heterophyllus)
This genus of hibiscus grows up to 3-6 meters high and has linear to oval-shaped leaves. The large flowers come in many colors including white, pink, and yellow with a red-colored center. The flower buds can be boiled or used raw in various types of salads and dishes. They’re also made into jam, making this a very useful plant to have in your garden.
Native Rosella mostly prefers warm yet moist environments. However, when taken good care of, it can also survive in cooler climates. It grows well in full sun and likes well-drained soil with a basic to neutral acidic level. It can be grown or propagated in the USDA zones 8-11.
4. Pink Cottonwood Hibiscus (Hibiscus splendens)
Also known as the “Native Hollyhock Tree”, pink hibiscus is another well-known species native to Australia. It has large, beautiful leaves and flowers as large as 150 mm in diameter which bloom in different shades of pink from spring to summer. The hairs on the flower capsules can cause skin irritation, so these plants should be handled with care.
Pink hibiscus typically flowers from spring through to summer and the flowers only last for a day or two. It requires well-drained, moist soil and can be grown in USDA zones 9-12.
5. Coast Cottonwood (Hibiscus tiliaceus)
Also known as the ‘Cotton tree’ or ‘beach hibiscus’, this plant has beautiful yellow flowers with a dark maroon or blackish center. Their color deepens to orange or apricot as they mature and they have beautiful, heart-shaped to circular leaves.
This plant can be grown easily in ordinary garden soil in the full sun or partial shade and require very low maintenance. It belongs to the USDA hardiness zones 10-12 and has a wide native range such as Africa, Asia, Australia, and the Pacific islands. In Sri Lanka, the bark and leaves of this plant is often used as a traditional ayurvedic treatment for fever, coughs, bronchitis, dysentery, and pulmonary diseases.
Tropical hibiscus plants are mostly native to Asia and constantly produce beautiful flowers in a wide range of colors. However, each flower blooms for just one day. In colder climates, these plants are grown as annuals.
Tropical hibiscus plants are very easy to care for since they only require adequate light and water. They’re also easy to propagate from soft-stem cuttings and don’t usually attract pests or get diseased. If you’re looking to grow a beautiful plant with vibrant, dramatic flowers, this is the right choice for you.

This hybrid tropical hibiscus species is popular for its outstanding big blooms. It produces dark burgundy flowers with black centers that are about 6-12 inches in diameter. It’s a slow-growing shrub that needs ample amounts of sun, water, and fertilizer. Due to its unique blooms, the American Hibiscus Society named it the “Hibiscus of the Year” in 2005.

Perennial hibiscus needs full sunlight but grows well in partial shade. However, it can affect the blooms. How well the flowers bloom depends on the amount of light the plants get so if you’re planting these in your garden, make sure to do so in an area that’s exposed to enough sunlight.
These plants are a lot easier to grow than tropical hibiscus. However, they’re not drought-tolerant and require quite a bit of water. They bloom best with enough water and about 6 hours of sun per day.
Hardy hibiscus is also a type of perennial hibiscus. Most hardy hibiscus grows well when planted in large containers with well-drained, moist, and nutrient-rich soil with organic matter. They should be watered well after the planting is done and you’d need to maintain a watering schedule to make sure they get 1 inch of water per week in the first year.
Hardy hibiscus is cold-tolerant plants that can withstand extreme cold weather which makes them ideal to grow in non-tropical regions with harsh winter conditions.
