Identification: Perennial shrub; flowers mid to late summer. Grows up to 10 ft tall. Leaves narrow, opposite and green to blue-gray. Flower heads lilac-like but come to a more definite point. Flowers small and purple.
Impacts: This plant is a pioneering species that dominates open habitats. It poses an ecological threat to dry-land meadows, open slopes and dunes, dominating these sites as much as Scotch broom has historically. It also invades reforested sites, resulting in a loss of forest productivity.
