Why the Diabolo® Ninebark - tree form standard?

Diabolo Ninebark is a bold, beautiful plant that has taken the gardening world by storm in recent years. What's all the fuss about? Chocolate-purple foliage, white half-snowball flowers, cherry-red fruits, and flaky bark - that's what! With all that going for it, you might expect it to be a bit of a diva, but it's sinfully easy to grow. Don't worry about counting the bark, check out those leaves! Amazingly beautiful, reddish-purple leaves line up on the arching branches. Beautiful, white flowers showcase themselves in summer. Exceptional color for your landscape. A must have! This native selection is a Gold Medal Plant Award winner from the Pennsylvania Horticultural Society for its outstanding performance, hardiness and eye-appeal.

Europeans are famous for taking underappreciated American plants, improving them, and re-gifting them back to us. Such is the case with Ninebark (so named because the flaky bark appears to have nine layers). Diabolo was discovered in a German nursery in 1968—the only red-leaved plant in a sea of 120,000 green ones (Germans must really like their Ninebarks!). This plant is usually grown as a shrub, but ours are trained to become small trees. Grown this way, Diabolo Ninebark shows off its devilishly handsome bark to best advantage.

How to use in the landscape?

Plant this fast-growing but small ornamental tree near your patio, pool, porch, or front walk for a punch of color all season long. You'll soon understand why we think Diabolo Ninebark is a "10"!

Why Bower & Branch?

At Bower & Branch, it’s our job to know and grow trees… especially big trees.

- Trusted, Experienced Growers

- Trusted, Knowledgeable Expertise

- Trusted Brand of Quality Trees Across the United States

We do the hard part. Our trees and plants are grown and cared for by only the best, local growers for years before they find their forever home in your landscape. Bower & Branch is known for having hard-to-find, substantial sizes and selection. The quality of our trees and plants are consistent in health and vigor—always ready for immediate impact in your garden and instant curb appeal. We never rush our trees to reach a 'grade size.’ Our trees are grown for quality height, vigor, health and age.

We believe in empowering homeowners with the truth about strong, healthy and structurally sound plants that are grown to perform in the ground after they leave the nursery for home delivery, always fresh inventory from the grower.

How To Plant

Despite the name, Diabolo is an easygoing guy. Give this plant full sun or very light shade, and average moisture (it can even handle drought-like periods once established), and it will give you a fresh crop of burgundy foliage each year. Little in the way of pests or diseases bothers it.

How To Water

Water weekly, or better yet, use the Bower & Branch® Water Element to deliver just the right amount of moisture to your tree throughout the growing season.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer, start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late fall. Continue this for the first three years to get your plant well established.

How To Prune

Diabolo is a fast grower so don’t be hesitant about pruning it if you want it to have a nice, dense head of foliage. Snip off any branches that appear on the trunk or at the base of the tree.

Hardiness Zone: 2-7


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 and shrubs, Size XL (A) and bigger, will take approximately 2 to 4 weeks to be delivered. - Sizes Large (AA) and smaller (Treelings, Shrubs, Bushes, and Perennials) 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!
