This semi-tropical shrub has become one of our go to plants for summer containers when a real blue color (not lavender blue) is called for. Tresses of light blue florets are produced endlessly. Where hardy this plant can grow 6′ tall and wide, but as a summer container plant expect it to fill out at 2-2 1/2′ the first season. Butterflies love it too!
Exposure: Sun/Part Shade
