'Perfect Storm' rose mallow is a hybrid cultivar of Hibiscus moscheutos, known commonly as the hardy hibiscus plant. It is part of Proven Winners' Summerific series. Perfect Storm is a relatively recent cultivar that is a compact version of the popular 'Summer Storm' hibiscus. With a mature height of about 3 feet, Perfect Storm is roughly half the size of its larger cousin, making it a better choice for small yards or beds. Thanks to its compact size, it also needs no staking.

Like other kinds of hardy hibiscus, Perfect Storm flowers late in the growing season, helping gardeners extend sequence of bloom in the landscape. It has a big, bi-colored flower about 7 to 8 inches across. The center is a deep, reddish-pink (with a prominent stamen, as is typical with hibiscus) and is surrounded by a lighter pink color streaked with darker veins. Each individual flower is short-lived but is quickly succeeded by more blooms. The foliage of this rose mallow becomes a very dark purple, almost black, highlighting the brighter colors of the blooms.

How to Grow Perfect Storm Hibiscus

Even though the plant functions as something of a small shrub during the summertime, it is a herbaceous perennial. This means it will die back to ground level in winter, before re-emerging the next year. It will be one of your last perennials to push up new shoots, though (sometime in May in a zone-5 landscape, for example), so do not give up on it when it hasn't come back to life with the other plants.

To clean up the space, prune out the old branches in spring before the new growth emerges (do not cut back in the fall). You can cut these dead, woody stems right down to the ground because the new shoots in spring push up out of the earth. Occasionally, the plant is attacked by aphids, mealybugs, or thrips. Inspect the leaves regularly for the presence of harmful insects. If you find any, spray the leaves with neem oil.


Hardy hibiscus will bloom best if located in full sun. It will survive with less sun, but it will not flower as much.


While Perfect Storm hibiscus will survive in soil of average fertility, it will perform better in more fertile ground. To achieve this, work soil amendments into the soil around it annually.


Water enough to keep the soil consistently moist, provided the soil drains well. To help with water retention in the ground, as well as drainage, mix compost into the soil.

Temperature and Humidity

Like most hardy hibiscus, Perfect Storm rose mallow can thrive in a wide range of temperature and humidity zones, provided it is watered regularly. It loves heat and sun but must stay hydrated.


To keep the plant well-fed, buy a balanced fertilizer at a home improvement store. Following instructions on the package, apply it once a year in spring. With a garden hose, wet the soil well afterward to make sure that the fertilizer goes down to the roots.

Common Pests/Diseases

Two common pests that attack hibiscus flowers are Aphids and whiteflies. The former usually form in clusters that can suck the nutrients from the flowers, and the latter are gnat-sized bugs that usually hide under the flower's petals.

Hibiscus can also be prone to fungal diseases that cause dark spots on the petals and leaves of the flower.
