Creeping Blue Blossom Overview

Ceanothus thyrsiflorus var. repens is a spreading shrub which has shiny, evergreen foliage. It grows with a vigorous, low and spreading habit that makes this species a great groundcover plant. In the spring, masses of light powder blue flowers appear in densely clustered panicle arrangements.

How to propagate Creeping Blue Blossom


Propagation through cuttings is considered moderately difficult. Semi-ripe cuttings may be taken from evergreen species from mid-summer through to autumn.


Ceanothus may be grown from seed, but they are difficult to germinate and plants are unlikely to be true to type. To grow from seed, physical seed coat dormancy must be broken before successful germination. First, soak seeds in hot water for 24 hours, then cold stratify for up to 3 months. Following cold stratification, keep at 16-18 degrees Celsius and germination should occur within 3 months.
