Looks like a Heracleum. If not one of these then probably another large umbellifer.

Here is a link that might be useful: Giant Hogweed

Ah, thanks for pointing me in the right direction. I'm thinking maybe it is Heracleum lanatum. I'll keep my eye on it.

i think if you are taking a pic of a "giant hogweed" maybe you would find a specimen bigger than two ball point pens wide.

KEEP YOUR EYE ON THAT HOGWEED, MIGHT BE THREE PENS BIG ONE DAY!

We're gonna need a bigger b-... pen
