ROSE PLANT Filed April 2, 1959 United States Patent O "ice ROSE PLANT Herbert C. Swim, Ontario, Calif., assignor, by mesne as-' signnients, to C. R. Burr and Company, Inc., Manchester, Conn., a corporation of Connecticut Application April 2,1959, Serial No. 803,812 1 Claim. (Cl. 47-61) The present invention relates to-a new and distinct variety of rose plant falling between the hybrid tea and floribunda classes (although tending more toward the hybrid tea class), said new variety-having been originated by me by crossing the variety First Love (Plant Patent No. 921) with the variety Roundelay (Plant Patent No. 1,280).

The general objective of this breeding was to produce a new rose variety having characteristics between those of the hybrid tea and floribunda classes, combined with a floriferousness at least equal to or better than either of the parent varieties, a bud form corresponding to that of the parent variety First Love, but the flowers of which have a greater number of petals, corresponding to that of the parent variety Roundelay.

A further objective of this breeding was to combine the aforementioned characteristics with a well-formed flower habit, and a habit of bearing flowers of medium size on stems of a suitable length for cutting, and a flower color ranging between pink and red. Still other objectives of this combination included vigorous, attractive and reasonably disease-resistant foliage characteristics. These objectives have been largely 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 from all other varieties of Which I am aware:

(l) A very vigorous, much-branched, generally upright plant habit;

(2) Attractive, dark green foliage of medium size and of better-than-average disease resistance;

(3) A very fioriferous habit, with the flowers borne sometimes singly and sometimes in small clusters on stemsof medium length;

(4) Moderately double, medium-sized flowers having 7 better-than-average urn-shaped bud form, with small points at the apices of most petals; and

An attractive flower color tonality generally ranging between Rose Madder and Phlox Pink.

In comparison with its seed parent, First Love, the new variety bears flowers sometimes singly and sometimes in small clusters, as distinguished from the usually singly-borne flower habit of this parent; and the flower color of the new variety is dark pink, while that of the parent variety is relatively light pink.

As compared with its pollen parent, Roundelay, th

- flowers of the new variety are less double; and the flower color is dark pink, as distinguished from the dark red flower color of Roundelay.

Asexual reproduction of my new variety by budding,

as performedat Ontario, California, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in difierent stages of development and as depicted in color Plant Pat. 1,8 93 Patented Jan. 5, 1960 as nearly true as it is reasonably possible to make the same in a color illustration of this character.
