An unusual representative of the daisy family, this succulent from South Africa is grown for its striking blue foliage of upright curvy fingers. It can fill a three-foot area as a groundcover, and is often used in containers or along walkways. Judicious pruning can keep the plant looking its best. We started with a tiny plantlet, full of potential, and are happy to see it's already expanded a good bit. It came through the freeze of January 2018 (24 hours of temperatures in the teens, with a helping of freezing rain for good measure) without any damage, so the zone 9 hardiness rating may be conservative. Definitely not grown for its flowers, which are unimpressive bordering on ugly (see photo below).
