For late winter. I planted kale, swiss chard, cauliflower, and broccoli.
When my winter squash and pumpkin (I have just one, a pie pumpkin) are harvested, I'll swing my little hoop house over the cole crops and the greens. Hopefully that will get them through the worst of our winter.
For fall: since the squash will be harvest in the autumn, I will call it a fall crop. Still hoping to have the grapes ripen. They are so close.
For spring: lettuce seed that I harvested today. It was all I could do to not try blowing the little puffs away.
The remains of summer: they aren't going to last much longer. I've been picking a handful or so of small cherry tomatoes everyday, a few larger ones as well. If it gets too cold at night I'll be making salsa with green tomatoes.
