Summerific® 'Perfect Storm' hibiscus is a new kind of rose mallow. When plant developers put their creations out on the market, one tends to ask, "What improvement has been made here to justify the introduction of a new plant? What are consumers getting that they could not have gotten from the older versions?" So let's have a look at just what, exactly, this Proven Winners® plant has to offer.

A Stormy but Tasty Series

First of all, do not consider the cultivar, Perfect Storm in isolation.

This new rose mallow plant is just one part of a series of plants within the Summerific® brand, all in different colors. The series includes:

  1. 'Cherry Cheesecake' (7-8 inch flowers of with a magenta or "cherry" red center surrounded by pinkish-white; up to 5 feet tall; zones 4-9)
  2. 'Cranberry Crush' (7-8 inch, solid scarlet flowers; up to 4 feet tall; zones 4-9)
  3. 'Berry Awesome' (7-8 inch, lavender flowers with a darker center; up to 4 feet tall; zones 4-9)
  4. 'Summer Storm' (see below)

These are all hybrid cultivars of Hibiscus moscheutos (known commonly as the hardy hibiscus plant) and similar species. As you can see, there is a "tasty" section in this series ('Cherry Cheesecake,' etc.) and a "stormy" section, of which Perfect Storm is a part (another member of the series is 'Ballet Slippers'; its flowers are a lighter color than the rest). The tasty-sounding cultivars may remind some gardeners of a series of Dianthus plants that also bear names that sound absolutely scrumptious, such as 'Strawberry Parfait' and 'Raspberry Parfait.' In both cases, the names have nothing to do with edibility; rather, they are meant to be suggestive and refer to the various shades of "fruity" pink and red that the flowers come in.

What's So Special About Perfect Storm Hibiscus?

In a nutshell, Perfect Storm is an improvement on Summer Storm. Specifically, it is a more compact plant. For this reason, it may be a better choice for small yards. But let's dig more deeply into the facts about this new rose mallow.

Summerific® Perfect Storm hibiscus reaches a height of about 3 feet tall (by contrast, Summer Storm can grow to be twice that height), with a maximum spread of 5 feet.

Because the plants are compact, no staking is required, which saves the gardener some work.

Unlike Summer Storm, which bears a more uniformly pink flower, Perfect Storm has a bi-colored flower: the center is a deep, reddish-pink (with a prominent stamen, as is typical with hibiscus), which is surrounded by a lighter pink color streaked with darker veins. The blooms are an impressive size, measuring 7-8 inches across (which, of course, is why people grow hardy hibiscus in the first place). Each individual flower is short-lived but is quickly succeeded by "reinforcements." Bloom time is late summer.

The foliage color of this rose mallow is dark enough (a purplish green) for it to qualify as one of the "black plants." Even though the plant functions as something of a small shrub during the summertime, this is an herbaceous perennial: plants 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, thinking that it is dead! To clean up the space, prune out the old branches in spring before the new growth emerges. Feel free to cut these dead, woody stems right down to the ground, because the new shoots in spring push up out of the earth.


The suggested planting zones for this perennial are 4-9. Grow it in full sun. Its soil should be consistently moist, but it must also drain well. It is said to attract hummingbirds and to be a deer-resistant plant.

What Exactly Is a "Rose Mallow?"

You may have noticed that I have referred above to Summerific® 'Perfect Storm' hibiscus as a "rose mallow" (which is synonymous with "swamp mallow"). This begs the questions:

  1. What is a mallow?
  2. What is a rose mallow, specifically?

"Mallow" can refer to a whole family of plants (in which case it is the common name for Malvaceae). But it can also refer to various genera within that family; most notably, Malva, which is the mallow genus. You may very well have grown a member of this genus in the past without knowing it. Are you familiar with the so-called "Zebrina hollyhock?" It is not really a hollyhock at all; it is, rather, a type of mallow plant: namely, Malva sylvestris 'Zebrina.'

Like MalvaHibiscus is a genus within the mallow family. So Perfect Storm hibiscus gets its "rose mallow" nickname merely from a family connection. That is, a particular species of Hibiscus (namely, H. moscheutos) has been designated "rose mallow" as a nod to its membership in the greater mallow family. And remember, Perfect Storm is a cultivar of H. moscheutos.

Other Kinds of Hibiscus

In addition to Hibiscus moscheutos and other perennials, there are a number of other members of the genus. There is even a weed in the genus called H. trionum. But the plant most people think of is the tropical hibiscus (H. rosa-sinensis), which is a shrub or small tree. This is the one that you may have brought home from the florist shop one year to grow as a patio plant (in a container) during the summer (those who live in a place like southern Florida can grow it outdoors year-round). It has waxy leaves that can get rather large (6 inches long and 4 inches across). The flowers can reach 8 inches across, can be single or double, and come in a multitude of colors.

If you live in the northern states of the USA, the hibiscus you are most likely to have grown in your garden is the shrub, rose of Sharon (H. syriacus), even if, until now, you did not realize that it is, in fact, a hibiscus. Read about some popular types of rose of Sharon in this article
