Why plant Ardens Rose of Sharon?

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!

“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!

How to use Ardens Rose of Sharon in the landscape?

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 Plant Ardens Rose of Sharon

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™ 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.

How To Water

They require keeping the soil moist (not too wet) after initial planting. Once established, they are more tolerant of drought conditions, reducing your hand-watering responsibilities.

How To Fertilize

During fall, feed your Ardens Rose of Sharon Bower & Branch Elements Fertilizer once a year for about the first 3 or 4 years - this will give your tree all the nutrients it needs.

How To Prune

Rose of Sharons don't always need to be pruned, but if you'd like to maintain a spherical shape, the pruning is best done in early spring.

How Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box! Our large trees require expert delivery and care, that means our large trees are shipped on Bower & Branch trucks. We are the only ones who know how to ship our big and bigger trees and plants with tender loving care.

We deliver your trees and plants directly to your driveway or curbside! Ask Bower & Branch about planting services and rates – we'd be happy to assist in installation.

*Big trees, Size XL (A) and bigger, will take approximately 2 to 4 weeks days to be delivered. - Sizes large (AA) and smaller (Treelings) will be shipped directly to your home by a local common carrier in a plant-safe box.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health.. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
