Cirsium occidentale - Cobweb Thistle

Description

Unlike the invasive thistles from Russia and Europe, this plant minds its manners. Planted in full sun or light shade, it will reach its mature height of 3' in late spring and then delight the gardener with its crimson flowers until as late as August. It is a Hummingbird favorite. While it occasionally seeds one or two volunteers, plan on it only living a year or two in your garden.
