Cotinus coggygria 'Royal Purple'

Royal Purple Smokebush

Botanical name: Cotinus coggygria ‘Royal Purple’

Overview
A bold, classic smokebush prized for its deep purple foliage that holds rich color throughout the growing season. In early summer, airy pinkish-purple flower plumes create a soft “smoke” effect above the leaves. Fall color intensifies to scarlet, orange, and red, providing outstanding seasonal impact. ‘Royal Purple’ is valued for strong color contrast and reliable performance.
