Winter Zucchini
zucchini landrace by Joseph Lofthouse
Here's a photo of my zucchini landrace 3 years ago. It's drifted a bit since then, in that I have selected for longer/larger fruits, and the color balance might have shifted.

And a photo of immature fruits from this summer at the farmer's market. The color shifted from week to week as different plants were more/less productive.
