Haha I was going to say, that’s not a weed — it’s yarrow!
Yarrow is resilient to mowing and light walking and grows into nice steppable lawn. It even blooms on teensy short stalks. I’m nurturing a patch to expand in my front yard.
In the backyard I have multiple patches of varying maintenance — some Are mowed occasionally, though not as regularly as the front, and some are grown in beds so I can harvest full size, unstressed healthy plant parts for herbal use like rainbowgardener mentioned.
Learning never ends because we can share what we've learned. And in sharing our collective experiences, we gain deeper understanding of what we learned.
