Botanical nameDiervilla
Diervilla 'Cool Splash' is a highly prized native ornamental shrub known for its bright variegated foliage and great hardiness in difficult conditions. It forms a compact, dense, and slightly spreading shrub, perfectly suited for mass plantings, borders, embankments, and low-maintenance naturalistic plantings. Its deciduous dark green foliage edged with creamy white brightens the garden from spring to summer, then transforms into spectacular purplish-red hues in autumn. In early summer, small pale yellow flowers appear, attracting pollinators and enhancing its ecological interest. Extremely hardy and well-adapted to Quebec conditions, Diervilla 'Cool Splash' tolerates drought, poor soils, and partial shade, making it an excellent sustainable choice for structuring the landscape with color and resilience.
