You're little seedlings look great! Are you overwintering them inside?
I've grown a few Salvia from seeds off my own plants but haven't tried Agastache yet.
I'm getting some seeds soon and I was wondering if you or anyone has any advice on growing them.
I do grow on a mat in Fall and winter and then I usually move the seedlings into my greenhouse until they are large enough to go outside safely.
I'm in zone 8b/9a so I can keep them from freezing easy enough. Does this sound like the right way to do it or do you think I should start them outside in Spring?
