genus for a large group of herbacious plants, with typically extended bloom periods. Mostly hardy to Zone 4, but some newer introductions favor bloom color and interest over winter hardiness.

One of the most popular cultivars, 'Hamilton', has particularly large stamens to go along with pubescent petioles. Notably fragrant and magical as it dances in the Midwest Summer breeze. If you've never seen this particular variety, it is truly worth seeking out for your garden. It is amazing. A true handful.
