They look just like Lady in Red Salvia seedlings. They are a bit fizzy but not as much as lambs ear.

It might be Scutellaria ovata, Hearleaf Scullcap. This blooms with light lilac flowers in late spring, then goes dormant over the summer. Grows from small tubers that spread by rhizomes.

Heartleaf Skullcap!

Thanks, Eric! I

had some of that, from one of the swaps, but I thought it had disappeared.

Yay!

I'm looking forward to seeing what it does this summer.

edited to add, Pam, I'm off to look up Lady in Red;
it sounds wonderful.

Oh my gosh Sylvia, they will take over your garden. I got a few seeds years ago and they have come up everywhere. They come back from roots too.

All that being said, in fall they will bloom on 4" tall plants. A gorgeous clear red, she's a Splendens and a hummingbird magnet. They usually grow to 4' and I cut them back when they look ratty from the heat. That's how I get blooms on short plants.
