PATENT OFFICE ROSE PLANT Application December 17, 1947, Serial No. 792,237

1 Claim.

My present invention relates to a new and improved variety of single hybrid tea rose plant. It was produced by me from a cross of two unnamed seedlings which in turn had been produced by me.

This new variety is of the same type as the variety Dainty Bess but has a pure white flower and is a much stronger grower. Other outstanding qualities of the new variety are its large well-branched bloom heads or trusses and its habit of continuously blooming from eary spring to advent of winter frosts. This combination of qualities makes it especially good when closely planted for use in hedges and for landscape effects as a border to taller growing roses, although single isolated specimens are also very efiective.

The accompanying illustration shows a bud, a partly opened flower and a newly full-blown flower, together with portions of stems and foliage.

Following is a detailed description of the plant and flower of this new variety. Any reference to colors indicates the ordinary dictionary meaning of the term.
