Usually every Spring is a blank canvas. The perennial flower beds have their regular arrivals and departures but the veggies need ordering, juggling, and finessing.
This year I have a volunteer...several in fact. If you recognize this red stem, these serrated leaves please leave me a note because I have no idea what this is.
Last year this bed grew onions (not very well), leaf lettuce, banana peppers, and a few volunteer potatoes that made it through the compost level of my raised bed.
This doesn't look like any of those to me or the local weeds. It looks the closest to my chard seedlings (didn't have any of those last year and I seeded them in the basement this year).
Whatever it is it's growing stronger then anything I've got out there right now, so I think I'll let it. I don't need that bed until cukes, squash, and melon go out in June.
