John Machen, Jr of Mobjack Nurseries registered this cultivar in 1994. It is a
tetraploid sport of H. 'White Christmas' that forms a large size (25 inches high by 63 inches wide) mound. The leaves are ovate
shaped, slightly wavy and smooth textured. Pale lavender flowers
are produced on 42 inch tall scapes from mid-July into August.
It is sterile and, therefore, does not set seeds.
The Hostapedia by Mark Zilis (2009), "It is an impressive plant, perhaps one of the best
white-centered hosta cultivars. It makes a much larger mound
with taller scapes than' white Christmas'..."

"As its mother plant,' white Christmas', fades into oblivion, 'Night before
Christmas' continues to increase in popularity. The reason is simple: one grows,
and the other does not."
