Plumbago 'Imperial Blue' (Plumbago auriculata)

Clusters of sky-blue flowers bloom from spring to fall and bring brilliant color to any sunny growing space. The phlox-like flowers are butterfly attractants and the flower clusters can reach up to 6" across. This South African native should be grown on a trellis since it can reach up 4-6' tall at full maturity. Also called Cape Leadwort.
