PATENT OFFICE ROSE PLANT ApplicationlFebruary 27, 1940, SerialNo. 321,109

1 Claim.

The present invention relates to a new and distinct variety of rose plant of the miniature type, the result of a cross between my prior dwarf origination Tom Thumb (Plant Patent 5 No. 169) and the highly Valued Polyantha Ellen Poulsen.

In my extensive Work in the field of miniature roses having the Lawranceana background, I have found none having as great attractiveness with respect to the form of the bud and flower,

and the color thereof has not even been approached by any flower of the small rose type. In addition to the foregoing distinctions, the size of the plant, small size and artistic arrangement of the leaflet and the large number of petals for so small a flower present novel features which make this variety entirely unique in the closs of dwarf roses.

In the drawing, I have illustrated in color a full size plant associated with a rule to show the actual size thereof and also a section of a garden planting of these roses to show their display characteristics.

A sexual reproduction shows that the variety 25. holds its distinguishing characteristics through succeeding propagations.

The following is a detailed description of this new rose, the color terminology employed therein being in accord with Ridgways Color Standard. Type: Hardy; dwarf; greenhouse and outdoors;

seedling; for cut flowers and garden decoration. Class: Miniature (chinensis minimaxPolyantha). Parentage: 35 Seed parent.-Ellen Poulsen. Pollen parent.Tom Thumb.

This description of a newly opened flower was made from a rose grown in a greenhouse, in November, 1939, at West Grove, Pennsylvania C'olor.outside petal: Outside surface- White faintly tinted with Hermosa Pink, Plate I; inside surfaceWhite. Intermediate petal: outside surface-White; inside surface-White. Inner petal: outside surfaceFaint Hermosa Pink, Plate I; inside surface-Faint Hermosa Pink, Plate I.

This description was made from a rose that was open for three days in a greenhouse, in November, 1939, at West Grove, Pennsylvania:

Color.outside petal: outside surface Hermosa Pink, Plate I with White base; inside surface-Faint Hermosa Pink. Inside petal: outside surfaceFaint Hermosa Pink. Inside surface--Faint I-Iermosa Pink.

Thorns-several, long, straight with narrow base. Pricklesnone. Hairsnone.

I claim:

A new and distinct variety of miniature rose plant characterized as to novelty by its dwarf size, the small size and arrangement of the leaflets, the form and color of the bud and flower, and the large number of petals thereof, substantially as shown and described.
