Ceratostigma are herbaceous perennials or deciduous or evergreen sub-shrubs depending on the species. The least cautious of them are the shrub species that manage to leave the base when the frost has made them suffer.
The small, oval leaves take pretty hues in the fall, ranging from red to bronze. They are deciduous for the perennial rhizomatous Ceratostigma plumbaginoides, which withstands -15° C, with its reddish stems.
Its five-lobed blue flowers with purple-red tubular throat and calyx are clustered in clusters and bloom in late summer, from August to October if it is not too cold.
This creeping plumbago can become invasive if it is allowed to grow as it sees fit.
