Cool Splash Diervilla Shrub for Shady Gardens

Brighten up the shade with a Cool Splash diervilla.

This cultivar of the southern bush honeysuckle was selected for its creamy to yellow leaf margins. The variegated leaves are topped by fragrant yellow flowers in midsummer. They help attract hummingbirds and butterflies to your garden.

Cool Splash is hardy in zones 4 to 8 and grows equally well in full sun or partial shade with moist well-drained soil. Once established, it is heat and drought tolerant.

This small-scale shrub suckers, forming a dense mass of cascading branches. It eventually reaches 2 to 3 feet tall and wide, making it suitable for small space gardens as well as mixed borders and shrub beds.  Use it to mask leggy stems or visually anchor taller trees and shrubs to the ground.

And don’t let the common name honeysuckle fool you. Though a member of the same family, this is not the invasive honeysuckle taking over our woodlands.

A bit more information: Combine Cool Splash with shade tolerant perennials. Hosta, astilbe, brunnera, coral bells and ginger are just a few. For more shade tolerant shrubs watch my Shrubs Made for the Shade video.
