Here in the Sonoran Desert, blue-flowering plants are rare, and of the few that are available, none can advertise the same stature and wild elegance as Imperial Blue Cape Plumbago. The sky-blue, phlox-like flowers are borne in clusters on the ends of multiple sprawling branches over a long blooming season, attracting butterflies from spring through fall.
Plumbago is deer resistant, drought and heat tolerant, vigorous, and fast-growing; easily rambling over sloped banks, climbing up fences and trellises, and cascading out of raised beds and planters. Taming this shrub requires some work, and keeping it formally trimmed will remove flowers, so we recommend giving it plenty of space for the most rewarding performance.
