Love these flowers, or maybe they don't qualify as flowers but what else would ya call them?! They are Globe Thistle and they are perennial. I started with one plant, quite a few years back and now I have many.....MANY. Everywhere. I love the look and if they are picked at the right time, they dry nicely. But ya gotta be careful picking them, the stems as well as the leaves are covered in thorns. I might put on the heavy duty garden gloves and pick several bunches to hang and dry.....or maybe not!
