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). Diablo 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, Diablo Ninebark shows off its devilishly handsome bark to best advantage.
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.
How to Grow
Diablo is a fast grower. 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. Despite the name, Diablo is an easygoing guy. Give this plant full sun or very light shade, and average moisture (it can even handle droughty 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.
