What's this?

I had never seen it before I planted tortoise weeds mix from AZ Tortoise Compound.

Never seen it before but love the way it's budding. Very interesting plant

it might be "selfheal" - Prunella vulgaris.

Thank you, Lochroma. I did a google search and Prunella vulgaris seems a likely candidate.
