Avalanche (Crousse).  8.7.  White.  A large, compactly built, globular cone shaped flower.  The blossom develops a distinct creamy white color which surrounds a center of delicately tinted lilac-white petals with a few wide petals edged with tracings of carmine.  Plant of medium height, strong, upright and a profuse bloomer.  A splendid flower for landscape effect.  A wonderful show flower.  At the National show held at Ontario this variety was awarded first as the best specimen bloom in the show.  Avalanche and Albatre are one and the same.
