With its glossy burgundy-red foliage, Red Zeppelin sweetshrub (Calycanthus floridus var. purpureus) will rock your world! The color of the foliage lasts all season and is accompanied by lightly fragrant orange-red flowers in late spring and early summer. Not only is it adaptable and easy to grow in the landscape, but our many years of trialing indicate it’s easy to grow in production, too. This selection of our North American native species was developed by the folks at Pleasant Run Nursery. Prune after flowering to maintain shape. Calycanthus perform amazingly well in eastern Kansas landscapes. It is great along a woodland edge or in morning sun, or in full sun for best foliage color show. It tolerates a wide variety of soil types including clay but needs prefers well-drained soil high in organic matter. Adaptable to mild drought and heat but greatly improved with rich, moisture-retentive soils. Typically, our 40 inches of rainfall per year in Eastern Kansas is sufficient. Summer foliage is virtually pest-free. All Proven Winners® plants are legally propagated, healthy and vigorous, true to name, and tagged with color pictures and growing information.
