Description: Native to South Africa, blue chalk stick is a hardy succulent with a beautiful blue-green foliage. It does best in bright, direct sunlight, so place in front of the brightest window you have. During the growing season, it is highly drought-tolerant once established and only needs to be watered every few weeks. For new plants, though, water once a week. Can grow up to 12" tall and 2' wide.
