Summer blooming purple flowers are attractive to bees, butterflies and hummingbirds.

See Details Below


Clusters of small, fragrant, tubular, purple flowers bloom atop tall stems for a prolonged period of time throughout the summer. They prefer moderately fertile soil with medium moisture and good drainage. This plant benefits from mulch, leaf litter, or groundcovers growing below, to keep the soil cool and moist. Good air curculation among the stems helps to prevent powdery mildew. Many cultivars are available, offering resistance to powdery mildew and an assortment of colors. Naturally occurs in open woods, moist meadows and moist roadsides. Companion plants include Blue Lobelia (Lobelia siphilitica), Cardinal Flower (Lobelia cardinalis), Eastern Blazing Star (Liatris spicata) and Orange Coneflower (Rudbeckia fulgida). 

Wildlife Value: Very attractive to a variety of bees, butterflies, hawk moths and hummingbirds.
