Diablo Ninebark
Black Hawthorn

Diablo Ninebark is a small, low maintenance, multi-stemmed shrub, that is used to add texture or color to any yard. This plant grows dark purple leaves in the spring and grows slightly faster than Common Ninebark. It features flaky red to brown bark, clusters of white flowers, and long, maple-like leaves. Diablo Ninebark can make a dense and colorful hedge, or it can be an attractive ornamental by itself.

Black Hawthorn is a versatile plant that is native to wetlands and other areas with moist soils, but can also tolerate dry soils. This plant can be grown as a short shrub, or a tree reaching 30 feet tall.

Black Hawthorn is valued for erosion control and attracting pollinators. It also makes an attractive flowering ornamental that can be planted as a specimen or pruned as a hedge. It is commonly used in shelterbelts.
