My old country farmhouse has an acre of grass full of dandelions, plantain, chickweed, common mallow, purslane, and lamb's quarters along with various grasses. At one point, I considered treating the lawn with a commercial broad leaf killer and fertilizer. Luckily, we scheduled a herbalist to do a herb walk showing the gathered friends all the food and medicinal plants growing in my lawn. My lawn still doesn't look like a golf green, but I feel like I'm walking on a carpet worth big bucks.
