Cirsium occidentale

The Cobweb Thistle (Yes, You Want This!) Forget everything you think you know about thistles. This California native is a sculptural work of art. Draped in silvery, "cobweb" fibers and topped with spectacular crimson-to-purple flowers, it’s the punk-rocker of the plant world. It’s also a high-priority pit stop for hummingbirds and butterflies. If you want a garden that breaks the rules and supports local wildlife, this silver beauty is a must-have.
