Hehe, actually, having plenty of zucchini was bit of a mistake on my part. These are from the seeds I saved from last year's harvest. I stored the seeds in a jar, but had not written a label on the jar, so in the spring I thought that they are pumpkin seeds. I planted them on compost heaps, hoping that as they grow they'll cover a large area suppressing weeds. Oh well, as they grew bigger I realized that they are zucchini.
