Unstoppable! When summer gets its hottest, and every living thing wants nothing more than to crawl into some cool shade, the Ardens Tree Form Rose of Sharon says, “Is that all you’ve got?” This perky little patio tree, also known as Ardens Althea or Hardy Hibiscus Tree, just keeps pumping out its double lavender blossoms through weeks of summer’s warmest, stickiest weather. Plant it by your front door, in your foundation beds, or in any of the borders or island beds around your home for a welcome, no-fuss pop of color. It’ll make you look forward to the dog days of summer!

Growth Facts

The Story

“I am the Rose of Sharon, and the lily of the valleys.” No, this isn’t the same Rose of Sharon of the Bible, but our Rose of Sharon, or Althea, has probably been grown as an ornamental plant since biblical times. For a long time, Westerners thought this Rose of Sharon was also from the Middle East, because it had been cultivated there for so many years. It actually originated in China and India. The Ardens selection is believed to have been introduced in 1873. This heirloom variety from your great-grandparents day was a favorite in the Victorian era and is still going strong today!

The Details

The Ardens Tree Form Rose of Sharon is also well suited to growing in a large decorative container on your deck or patio. Simply move it to where you need some pizzazz, like a versatile piece of living garden art.

How to Grow

The Ardens Rose of Sharon really could not be much easier to grow. All it needs is a sunny position (a lightly shaded one will do), regular water, and soil that drains well and doesn’t stay soggy after a rain. To keep the foliage vibrant and the flowers abundant, feed your tree in the fall with a good balanced fertilizer like the Bower & Branch Elements™ Organic Fertilizer. You may prune at any time, because the flowers are formed on “new wood,” and trimming in winter or spring does not remove flower buds as it does with Lilacs and so many other trees and shrubs. One thing you’ll want to look out for with this tree is self-sown seedlings—just pull them up when you spot them.
