Hoary Vervain

The robin's egg blue spires are a real standout in the late summer prairie. An important nectar source for butterflies, Hoary Vervain is an important component of butterfly gardens, and the leaves are the larval host food for the Common Buckeye Butterfly. The seeds are important for many small birds and mammals. Very drought resistant, and non-aggressive, Verbena stricta thrives on dry soils and well-drained loamy soils. Hardy to Zones 3 - 8.
