Parthenocissus quinquefolia, with spots

The leaves have all fallen now, but before they did I really enjoyed these strange chartreuse polkadots on the colored-up Virginia creeper (Parthenocissus quinquefolia) leaves...

I think this may have happened in the past? It seems vaguely familiar.

But then again, maybe not.

I have no idea what's caused the dots.

There's also that interesting shadow (photo paper) sort of thing happening. Very bizarre eh?

  1. Each polkadot has a lighter spot in the center, so my first thought was a bug, but then the shadowing you pointed out to make me think it's some sort of sun/light sensitivity during Autumn, maybe raindrops that lingered while the sun came out. I hope someone can figure out this peculiar phenomenon.

  2. Looks like a kind of leaf spot fungus to me. Probably the spores overwinter in the dead leaves/humus and then reinfect in spring. You might try spraying weekly in spring with Bordeaux mix or similar fungicide.

    1. Bordeaux mix is a new one for me. Naturally I first thought there was wine involved...

  3. That's odd. I've seen hail cause spots to appear on plants but never pretty green ones.

  4. That's interesting. It's really attractive, too. It sounds like you have some good advice, although maybe it's not a serious condition.
