Blooms in midsummer with elegant slender spires of lavender-blue tubular flowers. Finely divided grey-green leaves are aromatic when crushed. Perovskia has one of the longest bloom times 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, and it is so beautiful it deserves every foot of space it can get! Plant 24-36" apart. I suspect that Zone 4 reports of winterkill are from poor drainage rather than cold, so a cautious Z4. (bare-root crowns)
