Washington Hawthorn is an attractive ornamental shrub that is dense enough to plant as a privacy screen. It produces clusters of white blooms in late spring to early summer.

Washington Hawthorn's red berries last throughout winter, bringing squirrels and birds to your property. In the fall, its foliage turns beautiful orange, scarlet, or purple.

This species is also known as one of the more salt-tolerant species for those with saline soils.

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.
