Description:
A rare gem, this natural hybrid of Ceanothus thrysiflorus x C. velutinus from northern California is virtually unknown in cultivation, though Mike Lee at Colvos Creek Nursery once offered it. A large, not quite treelike shrub, it may eventually achieve 10 - 12' tall with greater spread, being fully evergreen and producing a show of large, clear blue flowers in mid spring. Owing to the C. velutinus parentage, it is certainly completely hardy west of the Cascades, having superior hardiness to the popular Ceanothus available such as 'Victoria'. And why don't more people know about this plant? We have no idea.
