i was wrong!
it wasn't a zucchini, it was a cucumber. we've got 2 cucumber plants with a TON of flowers and 1 golden zucchini squash plant.
more cukes at the top!
super teeny 1 inch zukes!
and here's the garden in the full sun - a little hard to see. pepper to the right in the container, super zingy arugula in the front, just a few plants, but more are coming up. maybe i'll try for better photos later, in better light.
