(C. pepo) We are odd enough here at Uprising to hold a blind zucchini taste-off, and I don’t recall Costata ever being unseated from the top spot (which perhaps ultimately begs the question, why do we continue to do this?) While its light green color and prominently ribbed fruit might worry some, we converted the majority of our market regulars to the superior and rich, nutty flavor of this unique-looking Italian heirloom. Big and sprawling plants produce prolifically with an added bonus of huge male flowers for stuffing. We continued to grow the regular straight green zukes for the non-adventurous and those wanting the comfort of the familiar, but these are the ones we eat at home. Our strain is the most uniform and productive we’ve seen.
