I am going to grow lettuce every winter until I am dead. It's the only vegetable I have consistently had good luck with.
The winter bed filled out impressively after the long, slow rains we had in late fall and then pretty much exploded this week after a huge storm dumped five inches of rain at our house and spun up an F1 tornado a mile and a half from here.*
Even in dry years when I have to water by hand, we get more than enough for salads. Since our hard freezes rarely last more than a day or two, if that, I just throw some plastic sheets and a big comforter over the whole mess and it sails right through. We'll eat off this until it gets really warm, when it'll get bitter and go to seed.
Half the beets are ready too, but I think I can leave them in the ground until I want to use them.
*It was an incredible storm with nonstop intense lightning, rain, and thunder that went on for hours, almost all night. Eric said the only time he was really concerned was when the wind whipped the plants on the porch every which way just before it started raining up, but it sorted itself out after a few seconds. Luckily no one was hurt, so I'll remember it fondly as one of the longest and most interesting storms I have ever seen.
