Hello all, I am recently retired and discovered my passion for gardening. The attached plant has popped up in my perennial bed and I'm unsure what it is. Can anyone help me identify it please. It seems to spread very quickly - on spikey stems and about 3 - 4 ft. tall. Thank you in advance.
Thank you so much MamaMac for your quick reply. Now that you say it, I realize you are correct. I googled for an image, and there it was!
