Cirsium occidentale ~ Cobwebby Thistle

Cirsium occidentale is a well mannered thistle in the garden. With flowers as spectacular as these, one might like for more seeds to germinate, but there will usually only be a few. The hoary silver foliage is strikingly sculptural. The flowers attract native bees, butterflies and hummingbirds. Cirsium occidentale is a nectar resource for the Cloudless Sulfur, Painted Lady, and Gray Hairstreak Butterflies. Cirsium occidentale grows 3-4 feet tall, usually with just a single stalk. The Cobwebby Thistle will come back after winter dormancy if they are planted in a dry enough location to keep from rotting. Cirsium occidentale blooms latter in the Spring into Summer.
