Monarda ‘AChall’ (Grand Marshall)

7 Photos


Summary

Monarda ‘AChall’, sold under the trade name Grand Marshall™, has gorgeous, deep-reddish purple flowers, a compact habit (28” tall), and excellent resistance to powdery mildew. What really sets Grand Marshall™ apart from other compact cultivars is that its growth habit is still Monarda-like, growing in a uniform mass that spreads slowly outward. Many of the newest compact selections are dwarfed to the point of looking artificial and out of place in the landscape. The habit of Grand Marshall™ habit better lends itself to blending with its neighbors in an attractive and natural way.
