Growth Facts

The Story

People have loved having Rose of Sharon in their gardens for centuries. Native to China and India, traders long ago brought its seeds to the Middle East. It was growing there—in Syria—when the first Westerner “discovered” it for the Western world and gave it a scientific name. Leonhard Rauwolf was that Westerner, a German plant explorer who travelled during the 1500s. On his journey to Syria, he also encountered a strange new beverage known as “coffee.” As for this variety of Althea, it’s a bit of a mystery. No one seems to remember who Collie Mullens was or where Collie Mullens Rose of Sharon originated.

The Details

Collie Mullens Rose of Sharon normally forms a bushy plant, but our growers have trained it instead to take the shape of a single-stemmed patio tree. This little accent tree is perfect for planting in your beds and borders, but you can also keep it in a large container. Use it as a sweet summer color spot near your pool or on your deck, patio, porch, or balcony.

How to Grow

The Collie Mullens Rose of Sharon is easy and satisfying to grow even for novice gardeners. Choose a site with all-day sun for your tree. It will also grow in part shade, but will put out fewer blooms there. This tree likes light soils and needs good drainage, but it doesn’t want to dry out completely. Irrigate with the Bower & Branch Elements™ Watering System to supply just the right amount of water and get your tree off to a great start. Collie Mullens will also respond favorably to an annual application of our Elements™ Fertilizer. This is one of the slowest trees to leaf out in the spring, so be patient! Pruning can be accomplished at any time of the year.
