Plant blooms on “old wood.” Take stem cuttings of about about 6 inches in summer to increase your perovskia plantings. Prune hard, to 6 to 10 inches, in the dead of winter while plant is dormant. Do NOT prune at other times or you will sacrifice blossoms.
…collected seeds… Just put your hand around a dried flowerstalk and rip the seeds off. They look a little wooly and at first sight…They were easy to sow…followed the instructions from Tom Clothier’s site: " Sow at 20ºC (68ºF), if no germ. in 3-4 wks, move to -4 to +4ºC (24-39ºF) for 2-4 wks ".
For optimal germination, soil temperature should be a minimum of 20°C / 68°F.These estimates for how long Russian Sage takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
