Horrid Thistle (Cirsium horridulum) NATIVE. This is definitely one of my favorite native flowers, and I don&#039;t think it gets nearly enough attention. Its defensive spikes can be quite painful if touched, but this plant is a pollinator favorite! Not only is it a host plant to The Painted Lady (Vanessa cardui) and The Little Metalmark (Calephelis virginiensis), but it attracts many other pollinators!<br />
