In 2000,
Peter Ruh registered
this sport of H. 'Northern Halo'. A 20 inch high and 40 inch
wide plant, it bears near white flowers in mid June.
According to
The Hostapedia by Mark Zilis
(2009), "...differs from 'Northern Halo'
only by its misted, green and white margin, but just that makes
this cultivar worth including in any collection."
H. 'American Mohican Halo' is a similar cultivar.
