Ways to Correctly Grow “Dinner Plate Hibiscus”

You’ve probably heard of Hibiscus even if you’ve never gardened before. It’s the tropical flower whose image may be found on Hawaiian print shirts and beach blankets all over the world. Many people are unaware that the term “hibiscus” refers to a variety of flowers, some of which survive in the heat of the south and others that are hardy up to Minnesota. Some are grown as houseplants, while others are perennials or shrubs that can withstand the elements. Let’s take a look at the perennial Hibiscus, also known as Rose Mallow, in this post.

Plant Overview

Rose mallow is a perennial that grows from zone 4 (think Minnesota, Wisconsin, and the like) to zone 9 (think tropical regions like Florida). It has some of the largest flowers of any perennial. You may have heard them referred to as “dinner plate Hibiscus” because of their large, circular blooms that measure 7-9 inches in diameter.

It’s difficult to believe that something with such a tropical appearance could withstand three months of snowfall. Many of the rose mallow types available at your local nursery were born and bred in Michigan’s zone 5b. Despite their cold-weather origins, they perform admirably in Texas and California trials as well. They’re extremely adaptable perennials.

Before you go out and buy rose mallow from your local store, there are a few things you should know about it. Let’s have a look at the criteria for selecting plants and what you’ll need to help them thrive in your yard.

How to Grow Them?

  • More Water

Water, and plenty of it, is the most critical requirement for rose mallow survival. Some native organisms are capable of growing in water. Plant it where the hose or sprinklers can reach it regularly. Do not allow this plant to wilt and dry up, regardless of whether your soil is clay, sand, or something in between. If it turns scraggly and drops its lower leaves and blossom buds, you know it isn’t getting enough water. Allow enough space in the landscape for your new rose mallow to shine.

  • Allow Them Some Space

Rose mallow is a huge perennial that takes up a lot of space. Even “dwarf” types grow to be at least three feet tall and wide, while standard-sized rose mallow grows to be 4-6 feet tall and wide. Find a spot in your landscaping where it won’t be overshadowed by other perennials, as it will swiftly outcompete them for space.

  • Bring on the Sun

The best spot for rose mallow is somewhere where the sun shines all day. It thrives in hot, humid, sunny weather, and its vibrant colors are best seen in direct sunlight. You’ll also have more blossoms. Rose mallow will grow in part shade if that is your only option, but it will produce fewer flowers, and kinds with purple leaves will appear greener.

Bottom Line

You’ll know the plant has woken up and is ready for some breakfast when new growth develops. Apply a balanced slow-release plant food to the surrounding soil to keep it fed for several weeks. Then, in early summer, just as its flower buds are beginning to form, feed it some water-soluble plant food to assist the plant to have enough energy to create a lot of flowers.

You’ll be able to develop prize-winning rose mallow with this knowledge. Every year from mid-summer to fall, we guarantee it will be the focus of your garden.
