Perovskia is a woody sub-shrub with long panicles of lavender-blue flowers that become increasingly brilliant as they open.
Common Name(s): Russian Sage
4' tall, 3' wide
Bloom Period/Days to Harvest:
July through Fall
Perovskia grows as a many stemmed clump with flower panicles at the ends of each stem. The foliage is finely cut gray-green leaves that are slightly scented. When fully in bloom it looks like a purple haze.
These are very easy to grow. They tolerate poor soil, a range of pH and drought. P. Atriplicifolia tends to flop to one-side. P. Login remain more upright.
Maintenance: Prune back to about 6" in the spring, before new growth starts. In warmer regions, deadheading may result in a second flush of bloom. Otherwise, leave the flowerheads for winter interest.
This is an airy plant that makes a great specimen. The lavender-blue works especially well with whites and yellows and with gray foliage.
P. Login is a narrower more upright plant than P. atriplicifolia
P. Filagran has delicate, especially finely cut leaves
