In today's episode of "I grow weeds. No, not weed, weeds", last year I found all purple and all white violets from areas further away (our neighborhood has half and half on the petals) and brought them into the yard. Then Romeo The Handful destroyed that garden bed while delighting in shredding my peas to find nummies. Thankfully though, the violet's exploding seed pods did their thing, just dug these out of the cracks on my driveway. I'll trim off the leaves and plant the rhizomes indoors :).
