Mature individuals of Feltleaf Ceanothus can become 7 meters tall (about 23 feet). The species name arboreus refers to this treelike stature. When in full bloom, Ceanothus is a breathtaking sight. The small but showy blue flowers are borne in hundreds of panicles or umbel-like cymes. Following pollination, each flower develops into a roughened 3-lobed triangular capsule that is almost black at maturity.
DISTRIBUTION: Dry shrubby slopes on the Channel Islands; < 300 m.
