I've never paid close attention to a trumpet vine before and I know they can spread like wildfire, but I didn't know they made seedpods. DH came in a couple of days ago with these. I find them very interesting... they look almost like they were molded with a form and the brown thing (whatever it's called..) at the top looks just like a tiny bell.
These were the only ones he found on the whole vine. I wish I had been there to watch him jump up and down trying to reach them...grin
