California aster. Perennial subshrub with densely tomentose, silver-white foliage and a profusion of lavender flowers from late spring well into summer. This cultivar can spread widely and climb over nearby plants under ideal conditions, so occasional pruning is recommended. Best used in coastal gardens as plants suffer where summers are hot. Full sun and well-drained soils with moderate water. Hardy to 20F. Santa Barbara Botanic Garden selection from the Big Sur coastline.
