DOT Plant Pat. 2,091

ROSE PLANT Sept. 12, 1961 Filed Nov. 22, v 1960 States Patent ROSE PLANT Pedro Dot, Barcelona, Spain, assignor to The Conard- Pyle Company, West Grove, Pa., a corporation of Pennsylvania Filed Nov. 22-, 1960, Ser. No. 71,108 l'Claim. (Cl. 47-61) The present invention relates to a new" distinct varietyof rose plant of the miniature class, which was originated by me by crossing the variety Pe'rla d'e Montserrat" (unpatented) with an unnamed and impatented seedling of Rosina (unpatented) Eduardo Toda (unpatented). I

The primary objective of this breeding was to produce a new rose variety of the miniature class, having" an irn- I proved plant habit and superior fiorifer'ousness as compared with previously known varieties of yellow miniature roses and presently available in commerce. This Objective was fully achieved, along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents; as well as fromall other varieties of which I am aware:

(1) A low-growing compact habit of growth;

(2) Superior floriferousness incompan'son with such varieties asv Baby Gold Star"; (Plant Patent No. 407) and Rosina (unpatented);

' (31) Attractive blooms of miniature size, ranging from 1% to 1 /2 inches in diameter;

(4) A distinctive Mimosa Yellow general color tonality of the blooms; and

(5) Ease of propagation by cuttings.

Asexual reproduction of the new variety by own-root cuttings, as performed at West Grove, Pennsylvania, U.S.A., shows that the aforementioned characteristics and distinctions come true to form and are established and Type: Hardy; dwarf; outdoor; seedling; for garden decoration.
