Ceanothus thyrsiflorus var. repens (Creeping Blue Blossom) is a low-growing, evergreen shrub noted for its abundant clusters of fluffy sky blue flowers from mid-spring to early summer. The flowers are so profuse that they literally cover the shrub, transforming the plant into an explosion of blue. The blooms are borne on horizontal arching branches clad with shining dark green leaves. Attractive to birds and butterflies, Creeping Blue Blossom makes an excellent evergreen ground cover. It is also useful on banks and slopes or in the foreground in mixed borders.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Grows up to 2-3 ft. tall (60-90 cm) and 6-10 ft. wide (180-300 cm).
  • Thrives in average, dry to medium moisture, well-drained soils in full sun. Appreciates afternoon shade in hot summer areas. Grows well in sand or clay. Established plants need little summer water (once or twice a month). Drought tolerant.
  • Excellent choice as a groundcover, for wall-side borders, bank stabilization or in butterfly gardens.
  • Prune immediately after flowering.
  • Propagate by seed or semi-hardwood cuttings.
  • Keep an eye out for scale insects, honey fungus and Phytophthora root disease.
  • Native to California, Oregon.
