'Royal Raspberry' has rosy purple flowers with burgundy calyxes. New foliage emerges with a burgundy cast in spring. Best performance comes in full sun with well drained soils. The buzz has already begun over this new collection of Agastache from Proven Winners® Perennials. Members of the MEANT TO BEE™ Collection were selected for their large, full habits, significant landscape presence, and hardiness. Flowers cover the top two thirds of these plants from mid to late summer, with colorful calyxes extending interest well into fall. Pollinators are known to frequent these plants and they are a particular favorite of hummingbirds.
