Santa Rosa Island sage
Salvia brandegeei “Pacific Blue”
Size: 3 to 4 feet tall and wide
Bloom season: Blue flowers in spring and early summer
Exposure: Full sun
Pruning needs: When young, cut back by one-third in late summer or fall to encourage compact growth. Mature woody plants need only tip pruning.
Water needs: Low; once established, water deeply once a month.
Snapshot: This handsome California sage is a variation of wild salvia from the Channel Islands. The “Pacific Blue” cultivar was discovered growing in the Santa Barbara Botanic Garden, which introduced it to home gardeners in 2004. With darker lavender-blue flowers than other Salvia brandegeei, this is one of the most drought-tolerant California native sages. Its handsome blue flowers bloom in whorls along 1- to 2-foot flower stalks throughout spring and early summer. Those flowers are nectar magnets for native pipevine swallowtail butterflies. In late summer and fall, the chocolate-colored seed pods are a popular food source for birds.
