This Canadian selection is very free flowering and bears exceptionally large blooms of a bright and showy pink that is a quantum improvement over the other pink Bee Balms we've grown. In our trials, 'Marshall's Delight' flowered from July into September, several weeks longer than other varieties. Highly resistant to mildew. Monarda is a North American genus of several species, all of which share tartly fragrant foliage and the square stems that typify the members of the Mint family. The late-summer flower heads are hemispheres of tubular blooms in brilliant colors. Plants thrive in full sun or partial shade and evenly moist soil. Under these conditions, they are vigorous to the point of invasiveness, perhaps past it. Hummingbirds are drawn to the flowers, which may suggest a location near a porch or a window.
