How to Care for Hardy Hibiscus Plants

Updated February 21, 2017

The hardy hibiscus (Hibiscus moscheutos), also known as the rose mallow, produces an attarctive bell-shaped flower that can grow 6 to 12 inches in diameter. The flowers come in various colours including white, red, purple and lavender. Cultivators love the striking, large flowers, making the rose mallow a prominent feature of many home gardens. The hardy hibiscus is a fast growing plant that does not need a lot of maintenance. Overall, it is an excellent choice for your flower bed.

Select a site for your hardy hibiscus plants that give it full sun or a light shade. Grow your plants in nutrient-rich soil for best results.

Grow your hardy hibiscus in the appropriate U.S. Department of Agriculture hardiness zone to ensure that your plant thrives. Hardiness zones are areas that have the proper climate conditions for a particular plant to flourish. The hardy hibiscus can do well in hardiness zones 4 to 10.

Grow hardy hibiscus in the moist soil it prefers. Make sure that the soil is well drained.

Put your hardy hibiscus in a pot rather than in the ground if you prefer. It makes a good container plant. Ensure that you water frequently to keep the soil moist.

Realise that the hardy hibiscus dies to the ground annually and grows back the next year from the roots. Avoid digging up a live plant before it has a chance to emerge in the new growing season.

Prune the plant back 4 or 5 inches after the first frost.

Tip

The hardy hibiscus is one of the last perennials to emerge in the new season. It may not start new growth until late spring.
