A large size (27 inches high by
74 inches wide) mounding plant, 'Northern Halo' was
registered by Walters Gardens,
Inc. of Michigan in 1984. It is a sport of
heavily corrugated foliage with thick substance. From mid-June into July, it bears
near white flowers on 32 inch tall scapes.

distinct forms of this cultivar being sold under this single name.
