About

Ceratostigma plumbaginoides is a low, spreading perennial that forms a dense mat through its extensive root system. Its oval green leaves transition to shades of red or purple as autumn approaches. From late summer, it produces clusters of vibrant blue flowers.

About the genus

Ceratostigma encompasses both evergreen and deciduous shrubs, as well as herbaceous perennials. The plants feature simple leaves that typically display vibrant autumn colors. In late summer and autumn, they produce short spikes of salver-shaped blue flowers that can emerge from the ends of branches or the leaf axils.
