Kronprinzessin Viktoria von Preussen Bourbon. Description... a sport of 'Souvenir de la Malmaison'... originated with Vollert, introduced by the nurseryman Späth of Berlin in 1888.  It came to light some years ago, having been treasured in the garden at Smallhythe, Kent, a property of the National Trust.  It makes a compact bush, and is in effect a pure white sport, showing lemon tinting in the bud and half-open flower, and is unique in bringing this tint to the Bourbon Roses.
