This sport of H. 'White Christmas' was registered by
Bob Keller of Illinois in 1996. The dark green leaves have a very narrow white medial
(center) variegation. It grows about 13 inches tall with a
spread of around 38 inches. The foliage is slightly rippled and
has smooth texture. Pale lavender flowers bloom from late July
The Hostapedia by Mark Zilis (2009), "...goes to the extreme of narrow leaf centers. Its white
center follows the midrib of the leaf blade and not much more."
