Rose plant Jaclopi

Abstract

A hybrid tea rose variety having rose pink buds and blooms on long, heavily prickled stems, little fragrance, long pointed leaflets.

Description

This present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by crossing an unnamed variety with an unnamed variety.

The primary objective of this breeding was to produce a new rose variety suitable for production of cut roses under greenhouse conditions with long stems, pointed buds and with a color in the pink hue. This objective was substantially 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:

1. Long stems, 18" or more, bearing pointed buds;

2. Few long prickles with many small prickles on stems;

3. Rose pink buds and blooms resembling closely the color, Red Purple 58C, of The R.H.S. Horticulture Colour Chart;

4. Very little fragrance; and

5. Relatively long, ovoid and pointed leaflets.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated:
