I do grow a lot of my own vegetables but have concentrated on the more expensive ones and use the farmer markets for my high volume needs like tomatoes
and peppers and onions. I grew patti pan (scallop) squash, zucchini
, lettuce, sugar snap peas, cranberry beans, sunflowers, jalapenos, spinach, beets (yellow and red), swiss chard (my favourite), kholrabi, fennel (didn't work out for me though), carrots, rhubarb and fresh herbs. I've saved a lot of money and so handy.
