Grown more for the foliage than the bloom, this plant is native to eastern USA. Listed as hardy to zone 6, it might be hardy to zone 5 if sited carefully. It likes a little afternoon shade in warmer areas.

I have had this plant in a partial shade with direct sun area and it has thrived, but not spread or self-seeded like the species S. lyrata. It grows in my awful clay soil, hasn't needed any supplemental water despite our high 90's heat and drought the past two summers.
The purple leaves are very pretty and nearly prostrate to the ground. Although it does bloom, I grow it mostly for the leaf color. A very easy plant here in Middle Tennessee.

'Purple Knockout' has wide, decorative, deep burgundy leaves. It is low growing, evergreen, and pretty fast growing making it a good plant for planting along pathways. Although its flowers are inconspicuous, its burgundy leaves are handsome. It needs full sun to mostly shade and dry to good soil.

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.
