Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of shrub rose, seedling resulting from a definite effort to produce an improvement in this class of roses.

BRIEF SUMMARY OF THE INVENTION

Primary features of this new variety which connote a distinctive advance over existing types are the gross abundant and continual blooming unlike its parent, Comte de Chambord, taken with the perfection of the fully double flowers of an old-fashioned shape, more particularly apparent in the accompanying illustration of a specimen thereof.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is a color photographic representation of a new variety of flush of bloom taken substantially in side view and showing inflorescence in various stages, stems and foliage of the plant.
