|[ Lyreleaf Sage (Salvia lyrata 'Purple Knockout') | Posted on May 11, 2019 ]
I planted two of the Salvia Purple Knockouts in 2017 -- this year they have large scapes with blooms and have multiplied a good deal. I am happy with this because I have another large area to cover and I can easily transplant them to different spots as it fills in.
One thing I've noticed is that the foliage is no longer as dark or purple as it once was. The underside of the leaves, however, is quite purple. I read the information on the plant's page and it indicated Purple Knockout is often self seeding but not always true to seed. I'll report back after I move them to an area with less direct sun and see if the leaves change.
