Abstract

A new variety of hybrid tea rose plant having a profuse and continuous production of medium sized flowers of a very soft pink coloration and a strong, slightly spicy fragrance, the blooms opening beautifully with a high centered bud which is long lasting as an open flower and which has a very long lasting vase life. The plant itself is very vigorous and free branching in its growth habit, reaching a height of about four feet, with strong upright canes and stems and a moderate production of foliage.

Description

BACKGROUND OF THE NEW PLANT

This new rose plant originated as a seedling resulting from a cross of Snowsong Supreme, U.S. Plant Pat. No. 2,624, and Pink Puff, U.S. Plant Pat. No. 2,634, made by the inventor at Livermore, Calif., in the course of breeding efforts to produce a hothouse variety combining the texture, keeping quality, fragrance and good imbrication of Snowsong Supreme with an unrelated fragrant, very productive floribunda variety Pink Puff to obtain a soft pink hybrid tea with increased production. In addition, it was desired to combine the leathery, vigorous and upright foliage of Pink Puff with the before mentioned good qualities of Snowsong Supreme.

This new plant was discovered by the inventor in 1971 and was subsequently asexually reproduced by him at Livermore, Calif., where further propagation by budding was carried on to test its capability of retaining its distinctive characteristics. Propagation of this plant by budding, through successive generations at Livermore, Calif., as well as Pleasanton and Hamilton City, Calif., has shown that the distinctive characteristics of the new variety hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWINGS

This new variety of rose plant is illustrated by the accompanying photographic drawings which, in full color, show in FIG. 1 a full face view of a newly opened flower; in FIG. 2 four stages of the bloom from a tight bud with sepals just cracked to a fully opened flower; and in FIG. 3 parts of the plant including top and bottom sides of typical foliage, a newly cracked bud and the form of the sepals, young wood, and two pieces of mature wood. The colors shown are as nearly true as can be reasonably expected to be reproduced by conventional photographic procedures.

The following is a description, in detail, of this new variety of rose plant with color designations according to The RHS Colour Chart published by The Royal Horticultural Society of London, England, in collaboration with The British Colour Council, the following date being from observations of greenhouse plants made at Pleasanton, Calif.
