Greg Johnson registered this
sport of H. 'Spritzer' in 2004.
It forms a medium size (12 inches high) mound of foliage which goes from pale
yellow to chartreuse as the season progresses. In August, it
produces pale purple flowers.
Similar cultivars include H. 'Tequila Sunrise'.
There is a non-registered cultivar from
Dr Dick and Jane Ward called H. 'Lullaby'.
