Blue Plumbago

Plumbago auriculata

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 the Blue 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 Flowers Flowers 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.

Light Needs: This shrub can take some sun in Arizona but we have found that if it is in the shade or is in partial shade it does much better.

Watering Needs: Water regularly – weekly or more often in extreme heat.

Average Landscape Size: It grows up to 6 feet high and wide.

Key Features: Can be trained as a vine or trimmed into a nice shrub.

Blooms: Intense blue flowers on and off throughout the year.
