Russian Sage

Perovskia atriplicifolia
An upright, shrubby perennial, reaching up to 5 x 5 feet, that is native to Turkestan, Pakistan and Afghanistan. It is woody at the base and can spread below ground. While called Russian Sage, this plant has no relation to true Sage ( Salvia ). Russian Sage is not eaten by deer or insects, rarely bothered by disease.
The finely-textured, deeply-cut, narrow leaves, up to 2.4 x 1.2 inches, are gray-green. The foliage is aromatic when rubbed or cut.
The profuse, tiny, blue-violet, tubular flowers are borne in hazy looking spikes, up to 15 inches in length, from mid summer into early autumn. The flowers look great with Ornamental Grasses, Shasta Daisies, Nippon Daisies, Rudbeckia fulgida and Echinaceas.
The stems are whitish in color.
Hardy zones 4a to 9 in full sun ( tolerates partial shade ) on neutral to alkaline, very well drained soil. Tolerant of harsh climates, it even thrives in parts of Alberta, Canada. It does not like soil that is excessively wet during winter. Salt tolerant, making it an excellent choice for use in parking lot medians.
Moderately drought, clay and very heat tolerant, it loves hot dry sites. Prune back to 6 inches from ground level in late autumn or early spring. Not generally eaten by rabbits and deer.
Propagation is from softwood cuttings taken during late spring.
Pharmacology: leaves are sometimes smoked like tobacco for its euphoriant properties
