A sight to behold! The leaves of 'Jack Frost' are intricately detailed with a crackle-like porcelain finish. Though the leaves are dark green they have a heavily frosted overlay which allows only the green veining to show through. From mid to late spring baby bluu forget-me-not type flowers are held in clusters several inches above the shimmering foliage. Simply breath-taking. Hardy in Zones 3 to 8. 12 to 15" tall. Deep Shade to Part Sun.
