Last year I got spaghetti squash seeds from my BIL. There were two kinds of seeds. The regular spaghetti squash and a variety I had never seen before. Half of them were green with white stripes, and half looked like a zuke, just 1.5 times as large. {there are pictures of them on this thread. Not sure of the page number}
Anyway, I saved seeds from them, but can not find them now. I ask the BIL if he still had the original seeds. I had bought spaghetti at the Co-Op and planted a few rows of them, but planted a few of his too, just in case they are the long green kind.
