Dan,
I ordered Heatwave Glimmer from Bluestone Perennials. I'm sure they'll have it again for 2019. They didn't have any other Heatwave salvia, though.
I've always loved Heatwave Blaze, since it introduced. I couldn't get it this year (sold out) with my 2 orders at FBTS. Hopefully, next year.
My SS is still blooming its head off in the container it's in. A hummingbird favorite.
