Rose plant

Abstract

A rose plant of the Hybrid Tea Class obtained as a seedling from a seed parent of the White Satin variety U.S. Plant Pat. No. 2,648) and unnamed pollen parent U.S. Plant Pat. No. 2,603. The rose plant of the new and distinct variety freely yields long lasting large blooms borne on long stems on a continuous basis in a greenhouse.

Description

SUMMARY OF THE INVENTION

The object of the present invention is to provide a hardy rose plant of the Hybrid Tea Class which is capable of freely yielding quality cut flowers under greenhouse conditions.

The variety of rose plant of the present invention was obtained at Aalsmeer, Holland, as a seedling from a seed parent of the White Satin variety (U.S. Plant Pat. No. 2,648) and unnamed pollen parent U.S. Plant Pat. No. 2,603. The crossing was made during 1972, the sowing during 1973, and the first flower appeared during 1973. The new variety was initially designated Rose U.S. Plant Pat. No. 3,667.

Asexual reproduction of my new and distinct variety shows that its unique combination of characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE DISCLOSURE
