Yay I'm harvesting tomatoes (these are mostly saladette size)
...and arugula and spinach that were started in my winter indoor garden (seeds were sown in 1 gal containers back around Christmas time and kept in unheated garage under lights).
Outside, I have survivors -- spinach, mustard greens, broccoli (harvesting side shoots), purple sprouting broccoli, and Swiss chard that were under double-cover plastic film low tunnels.
I also intend to dig up/harvest parsnips and am harvesting Egyptian walking onions (looking beautifully lush and dark green), Chinese celery, Japanese parsley, and garlic chives, that overwintered in open beds.
Cilantro and baby Red Russian Kale and one purple cauliflower and 4 more white cauliflower as well as onions and leeks that overwintered are not big enough to harvest yet, but they are starting to grow. I have some purple Brussels sprouts that overwintered but their sprouts seem to have "blown" in last week's heat wave. I might still harvest and eat the little opened sprouts. I have self-seeded radicchio scattered around two garden beds that can be harvested as 3-4" outer leaves, but left to grow, they should form heads.
Rosemary outside and inside (also overwintered inside lemongrass, lemon verbena, and applemint) are always available, out in the garden, oregano, catnip, peppermint, spearmint, applemint, and lemonbalm are starting to come back enough to harvest in small snips. Thyme, too I think.
