Even if you’ve never gardened before, you’ve probably heard the name Hibiscus. It’s the iconic flower of the tropics with its image splashed across Hawaiian print shirts and beach blankets everywhere. What many people don’t realize is that the name Hibiscus is used to describe many different kinds of flowers, some of which thrive in heat of the south and others which are hardy all the way north to Minnesota. Some types are grown as houseplants, while others are hardy perennials or shrubs. In this article, let’s look at perennial Hibiscus, commonly known as Rose Mallow.

Water, water and more water
The most important thing rose mallow needs to survive is water, and lots of it. Some of the native species can actually grow IN water. Plant yours in a spot that can easily be watered on a regular basis. Whether your soil consists of clay, sand or something in between, do not let this plant wilt and dry out. You’ll know it is not getting enough water if it becomes scraggly looking and drops its lower leaves and flower buds.
Give me some elbow room
Rose mallow is a large perennial that takes up a lot of room. Even varieties that are considered “dwarf” grow at least three feet tall and wide, with standard-sized rose mallow growing 4-6 feet tall and wide. Find a place in your landscape where it will not be crowded by other plants, because it will quickly outcompete your other perennials for space.
Bring on the sun
The best place to plant a rose mallow is somewhere the sun shines all day long. It loves hot, humid, sunny weather and shows its best colors in full sun. You’ll have more flowers too. If your only option is a spot in part shade, rose mallow will grow there but fewer flowers will be produced and varieties with purple foliage will appear more green.
