That dude is cool! Welcome to visit my yard anytime.
I saw this plant behind a bank in a nearby town so it's not readily accessible but whenever I go back over there, I'll check on the spot again & pull a few leaves to sniff.
I would LOVE to find some seeds. Whatever this plant is, it would be right at home in our "lawn" with all of the other micro-bloom plants already battling it out, out there. So far, I've had zero luck trying to introduce new plants to the mowed area, so clearly more effort is needed. The grasses are rough garbage vines, but the micro-bloom plants are great!
