Agree. Perfectly normal leaf coloration.

Your question has already been answered, but I'm curious, do you know what variety you're growing? The variegation is very nice!

I have no clue. It was purchased at Home Depot. The brand is Bonnie. Sorry I can't provide more info.

My delicata squash's leaves look like that.

As noted, fungus/mold brushes off. Silver veining does not. Mature squash leaves often develop silver splotches naturally.

What a relief. I've had nothing but a struggle with zucchini purchased as plants this year instead of seed as I normally do. I figured I was just doomed, yet again, with this store bought stuff. Phew and thanks to all even though this is an old post.

Those are what my leaves look like and i stumbled across this post. The type of zucchini is called 'noche'

It is not possible to name a cultivar from the leaves. Many different zucchini cultivars have exactly the same kind of markings.

Thank you for this asked and answered post. I came with the same question (also from Boston) and my zucchini are Green Machine from a local nursery. I am so relieved!
