What is Perennial Hibiscus?

7 images of beautiful blooming hibiscus flowers.

These are hardy hibiscus plants that can survive being grown in zones 4 to 9.

Depending on how well you care for them during the winter season, they will return again the following year. Perennial Hibiscus is a variety of grown hibiscus.

Hibiscus on its own comes in just two varieties - we have the hardy Hibiscus and tropical Hibiscus.

The difference?

No significant difference as both are known to be perennials, but, more often than not, we see the tropical being grown as an annual hibiscus in very cold climates.

Choosing which to plant can be very confusing, so we have outlined a list of 21 perennial hibiscus varieties in no particular order.

Shall we?

This plant gives an angelic white bloom all summer! The flowers are crisp white, and the foliage green.

The White Chiffons grow extremely large; their fluffy centers lighten up your gardens at night during summer.

How To Grow And Care For Perennial Hibiscus

As with every other plant, the perennial Hibiscus has its own peculiar way of being grown; plus, there are some care tips you must know about to sustain the plants year in and year out.

Planting Location Tips

Generally, Hibiscus is not known to be a problematic plant. As long as you follow the right process, you should not have anything to worry about.

When planting the Hibiscus, put into consideration the fact that these are sun-loving plants. They require a great deal of sunlight in order to spring forth those beautiful, shiny and smooth flowers that we so love them for.

Therefore, a factor that into your planting spot decision process and makes the right choice.

For emphasis' sake, the right choice of a planting site would be one in which the plants can get 6 hours of sunlight daily, at the very minimum.

Soil Needs

Hibiscus really does not require any kind of special soil. Bring forth any well-drained soil, and you are good to go. Waterlogged soil is a starter pack for failure in your planting journey.

The reason is simple; We all know that the Hibiscus plant requires a great dose of water as it grows, but then the root requirements are the direct opposite; they cannot stand water, hence the need for well-drained soil for them.

Confused as to what kind of soil counts as a well-drained one? Sandy or loamy soil are safe choices for you.

Furthermore, your plant will do well if you feed the soil in which they are grown and the necessary nutrients they need to thrive, like; manure and compost.

Have the organic matter, i.e., manure and compost, mixed with the soil before planting, then water immediately. Not to worry, the soil would ensure it gets drained in record time. See that the plant is watered daily, especially in the early weeks.

One last thing though; as you plant, see to it that the soil covers the whole root ball for maximum effect.

Hibiscus Spacing Requirements

Hibiscus plants are planted in soil and in pots.

No mincing words here; the hibiscus plant requires ample space for growth.

Just in case you didn't know, the hibiscus shrubs have the potential of growing as tall as 8 feet high and many feet wide.

Therefore, you need a very spacious environment to carry out this project effectively.

Because of their tendency to spread wide, there is a need to have them planted at least 4 ft away from each other.

It is also advised that you plant Hibiscus close to a wall for Hibiscus plants that develop wood-like stems. You can equally place a stake to support those non-wood ones for proper balancing since they are prone to stay bent out of shape.

Moisture Needs

Hibiscus needs the most water in the early weeks and during their period of bloom. The risk of leaving your Hibiscus plants to dry out is very grave. You will experience a drop in its foliage and stiff-looking dead plants.

To prevent this, have it watered and, at the same time, see that the water drains out and does not sit in for long to avoid the root rotting.

Pruning The Plant

Gardener's hands with sheers cutting hibiscus flowers.

The benefits of pruning include more supple flower stalks and branching.

Pruning keeps your plants looking neat and tidy and also accelerates the rate at which the next bloom occurs.

For effective pruning, have the exercise done in early spring and cut down on the plant by one-third.

Fertilizer Needs

The application of fertilizer guarantees adequate nourishment for the plant. To this end, you are required to apply fertilizers at the base of the plant directly at least once a week or month, depending on the type of fertilizer you are using.

In summer, though, a potassium-dense fertilizer is advised, and in winter, a drastic reduction in the rate at which you water and fertilize the plant is expected.

A moderate fertilizer application is still the best as too much phosphorus can lead to the death of the plant, and too little application would see them nutrient starved.

Frequently Asked Questions

Do You Cut Back Perennial Hibiscus?

You should. Cutting back helps to eliminate dead stems and branches in order for more flowers to emerge.

Where Should I Plant Perennial Hibiscus?
