I saw this growing in my front yard a few weeks ago, and it's gotten bigger & bigger and BIGGER. It's HUGE. It covers about a 6' area, each leaf is at LEAST a foot in size. It bloomed this morning. I'm thinking a watermelon/pumpkin/cucumber or something. Not vining. I didn't plant it, it's a volunteer. Don't know what or where though. And what's really odd about this plant is that the leaves have these interesting white speckles on it.. like freckles.
Any idea? I guess I could just wait until the fruit starts to grow from the flower...
