This is one of the showiest of the skullcaps. Plants grow to 3 feet tall and 18 inches wide or more. It enjoys medium to dry soil and partial sun. Nectar-rich blue blossoms are prominent in the garden from June to September. This native perennial has a spreading habit. Like many species in this genus, hoary skullcap has a long history of medicinal use. It's reported that indigenous peoples used this plant as a sedative for nervousness and anxiety — and we expect lots of people are once again appreciating this plant for this virtue.
Our seed was produced by our friends at Ernst Conservation Seeds in Meadville, PA.
