Low Water Plants For the California Bee Garden: Russian Sage

Conserving water and helping bees are goals shared by many gardeners. Given California's current extreme to exceptional drought status, it's time to re-visit the best low water plants for bees. Haven scientists are nearing the end of a long-term project examining bee preference for commonly used landscape plants. We've focused on low-water plants for northern California, while our San Diego-based colleagues have focused on southern California plants.

One of the consistently most-preferred plants has been Russian sage, Salvia yangii, formerly Perovskia atriplicifolia (read about its reclassification here). It's been either the first, second, or third most attractive plants to honey bees, and second, third, and sixth most attractive plant to native bees over the course of our observations.

Native to central Asia, this plant copes well with hot, dry conditions as well as extreme cold. It blooms from late spring to frost, providing a season-long bee resource. Like most members of the Lamiaceae, it serves only as a nectar source. Pair it with a complimentary colored pollen-providing plant in pink or red, like the coneflowers shown here, for both garden interest and bee nutrition.

Gardeners who have dismissed this plant in the past due to its large size (the species reaches about six feet tall) now have options. The cultivar 'Blue Spire' tops out at about four feet tall, while the aptly named 'Little Spire' is only about two feet tall.
 
Very easy to grow, the only trick to care of this plant is to know that it blooms on new wood. Even though it's a woody shrub, prune to about one foot tall in winter to stimulate new growth that will produce flowers. This plant needs full sun, little water, and grows in Sunset zones 2-24.
