I bought yellow zucchini seed and maybe a couple plants this year. They don't keep! I kept a few in the frig and a couple on the counter for a few days and they are spoiling. Good ole green zuccs are sitting in the frig and counter and doing just fine! (I think they are related to Twinkies. ) The yellow ones are nicely prolific, good size and shape, but I want something that keeps better until I decide to eat them or gather enough making it worthwhile to make squash pickles, freeze or to dehydrate.
