I've been identifying some weeds that are growing in the spot where we throw our tree trimmings/pulled weeds/etc. Since cleaning up long-neglected sections of our property is a never-ending project around here, it's quite a big pile. An unbelievable variety of things grows around and over it each year. We like the wild blackberries best, but so do the birds and the bunnies and the chipmunks and the squirrels and whoever else is living over there.
Teasel (Dipsacus fullonum), with its egg shape, spikes, and purple flowers, was easy to find with google. I'm having a harder time with this one, which I don't remember seeing in previous years.
Can anyone tell me what it is?
