Russian Sage is a genus of sub-shrubs grown for both foliage and flowers. They have highly scented, often silver leaves, topped by long spikes of tiny blue or purple flowers in late summer.
There are only about seven species, native to central Asia, across to Afghanistan and Pakistan, where they grow on dry plains.
They prefer a sunny site and require well-drained soil. They will tolerate periods of drought, but dislike winter wet, so are ideal for gravel gardens. Some winter protection may be required in harsher climates.
