36-48" tall. Formerly called Perovskia atriplicifolia.
Elegant slender spires of small lavender-blue tubular flowers in midsummer have a misty appearance from a distance. Finely divided grey-green leaves are aromatic when crushed. Among the longest blooming of any blue-flowered plant. Semi-woody shrub emerges slowly in spring; cut back after frost.
Tolerates drought, loves heat and full sun, can’t bear standing water. Likes to spread out once it gets established—we think it deserves every foot of space it can get! Plant 24–36" apart. Native to central Asia. We suspect Zone 4 reports of winterkill are from poor drainage rather than cold, so a cautious Z4.
