Verbena bonariensis

For sunny, well drained soils. Tall rigid branching stems are topped with tight-packed flat clusters of small, mauve, scented flowers loved by butterflies. Standing high above the silver plants they make summer 'screens' to view the garden through from late summer to autumn. Don't cut down too soon in order to allow the plant to set seed. The mother plants can succumb to the winter and self-sown seedlings provide insurance. They are also as attractive out of flower, maintaining structure to the years end.
