#ProPlantTips for Care:
Altheas performs well in almost any soil, except if it's too dry or too wet. This easy-care plant is a perfect choice, whether you are a beginner or have years of landscaping experience. Rose of Sharon loves sunshine! Plant it in a spot where they will get at least six hours of sunlight a day. Provide a moderate amount of water on a regular basis. Use a three-inch layer of arborist mulch over the top of the root system to keep them nice and cool.
This pretty shrub blooms on new wood, so prune Althea in early spring to either shape or control the height. You'll have flowers later that season, no matter how tightly you trim them in spring. You can even train these shrubs into multi or single-stemmed tree forms! Renewal prune every 3-5 years to maintain vigor. Apply a slow-release fertilizer designed for flowering plants at the same time. Follow application rates on the label.
Azurri Blue Satin® Rose of Sharon actually has reduced seed production, making this plant nearly sterile. Use anywhere in your yard without worrying about nuisance seedlings. In some areas, these seeds can sprout, so Nature Hills employs Plant Sentry™ to ensure these plants won't ship into areas where they can become a problem.

Tree Form vs. Shrub Form
The details make all the difference in a garden. At Naturehills.com, we understand that little things like what form a plant is can greatly impact how you plan your landscape. So before you buy, don’t forget to check which form you're getting.
Tree Form:
These are plants that have one stem coming from the ground. Plants can also be considered single stem when lower branches are removed to raise the height of the branching to a more desired height. Sometimes, you will hear a tree form referred to as a single stem.
Shrub Form:
These are bushy plants with many stems and branchings close to the ground. They are referred to as shrubs or bushes and are often shorter than their tree forms.
