Lives up to its name! Thick, puckered, broadly ovate leaves are slug resistant. Wide, irregular, blue-green margins surround an ever-changing center; starts out chartreuse in the spring, turns to yellow, then to creamy yellow, and finally to white (colors vary with light levels). Fern green streaks are painted between the margin and center of each leaf; every leaf is unique. Dense masses of white flowers are displayed just above the foliage on 24" scapes in early to midsummer.
