Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Prefers moist, organic soils. Best grown in full sun with some afternoon protection. ROZANNE has exceptional heat tolerance, and generally will bloom throughout the summer. If flowering stops and/or plant foliage depreciates in the heat of the summer, plants may be cut or sheared back to rejuvenate, shape and/or encourage additional bloom. Side stems may be removed or trimmed at any time to control spread.
