A tetraploid sport of 'Ambrosia', 'Twice as Nice' enhances every quality of its parent — a brighter yellow center, wider, bluer margins, and all the vigor that comes with improved genetics. The margins are deeply blue in spring, softening to blue-green as the glaucous bloom fades, while new leaves continue to emerge through summer. Fragrant large white flowers arrive in late summer — a final, welcome indulgence.
