Centaurea dealbata

Star Thistle, Knapweed, Persian Cornflower

Easy to grow, this member of the daisy family is good for borders or wild gardens. Most annual types are grown for their frilly, cuttable flowers, and perennials for their felty, gray foliage. All like sun, and some are drought-tolerant. Attract birds. Start easily by seed in spring or fall or division. Self-sows, so may pop up where it is not wanted. May need staking.
