A San Remo, Italy Filed July 22, 1964, Ser. No. 384,565 Claims priority, application Italy, Aug. 23, 1963, 17,295/ 63 1 Claim. (Cl. Pit-11) The present invention relates to a new and distinct variety of rose plant of a class falling between the dwarf or miniature type and the hybrid tea type, which was originated by me in the course of an extended breeding program culminating in the crossing of two unnamed and unpatented varieties respectively identified in my breeding records as Hybrid No. 103 CG. and Hybrid No. 1896.

Heretofore, many varieties of rose plants now grown for cut flower production are not suitable for other floral use because of their large flower size and other qualities which sometimes present difficulties in the culture and utilization thereof. Accordingly, the primary objective of my breeding program referred to in the foregoing was to produce a new type of rose variety which maintains the overall beauty and harmony of flower shape characteristics of the best out flower varieties. But with the flowers and stems being of a reduced size in comparison with the usual types, and thus falling in a class between dwarf and hybrid tea types, while bearing the flowers singly to the stern instead of in clusters, and having their shape, growing habit and scent quite similar to those of the largesized varieties. This objective has been fully achieved in my new variety, along with other desirable features which altogether represent a unique and distinctive-combination not found in any other variety known to me, as evidenced by the following characteristics which are outstanding in the new variety:

1) A shape of the plant, stems, leaves and flowers like those of hybrid tea roses, but harmoniously reduced in size and presenting a more elegant appearance;

(2) Rapid growing and free blooming habits in all seasons of the year, and consequent suitability for both outdoor and greenhouse culture;

(3) Numerous and erect main branches or canes, starting from the base of the plant and bearing numerous,'thin, woody, rigid, erect and elegant-floral stems having few or no thorns, which produce flowers on thin, rigid and erect peduncles;

(4) Small, light and decorative leaves which clothe the plant and floral stems in an attractive and harmonious manner;

(5) A habit of bearing the flowers single and terminally on the stems, with the flowers ranging from small to medium size;

(6) An urn-shaped flower form on opening, but becoming flat-cupped as the flowers age;

(7) A distinctive and attractive general color 'tonality of the flowers ranging between Tyrian Purple and Spirea Red;

(8) A delicate but permanent flower fragrance;

(9) Good weather and disease resistance, and especially good resistance to fungus diseases such as, blackspot and mildew;

(10) Good flower shipping qualities;

(11) Very long lasting flower qualities as cut flowers; and

(12) Ease of reproduction by bud grafting and by rooted cuttings.

Asexual reproduction of my new rose variety by bud grafting and by rooted cuttings, as performed by me at Sanremo, Italy, shows that the foregoing characteristics and distinctions cometrue to form and are established and transmitted through succeeding propagations.
