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 the hose or sprinklers will reach 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.

Leave lots of room for your new rose mallow to shine in the landscape.

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. Full sun brings out the best colors and most blooms on rose mallow.

Give me some attention in spring When all of the other perennials in your garden start to show signs of life in early spring, don’t be worried that your rose mallow is still fast asleep. It is always one of the last plants to show new growth in spring. Once it starts growing, it will grow about an inch a day and start to bloom in midsummer.

Before you see the new foliage appear in spring, take a strong pair of loppers or pruners to cut down all of the woody stems to about 6 inches tall. The new growth will appear from the base of the plant, not those brown stems, so it’s a good idea to remove them.

When the new growth appears, you’ll know the plant has woken up and is ready for some breakfast. Apply a balanced slow release plant food to the surrounding soil which will continue to feed it for several weeks. Then give it some water soluble plant food in early summer just as its flower buds are beginning to form to help the plant have energy to produce lots of flowers.

Equipped with this knowledge, you’ll be able to grow prize-winning rose mallow. We promise it will be the highlight of your garden every year from midsummer into fall. Save the label when you plant it, because your friends and neighbors will surely be asking you for ID!
