Hybrid tea rose plant named TANalephar

Abstract

A hybrid tea rose plant having a low petal count; thick, leathery petals; strong, vigorous, upright growth; unusual orange-red flower color, and a very long vase life.

Description

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

The primary objective of this breeding was to produce a rose variety having the long stems and orange-red color of the female parent combined with the excellent vase life, large flowers and orange-red flower color of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Unusual orange-red flower color;

2. Exceptionally long vase life;

3. Few petals, but very thick and leathery;

4. Vigorous, upright growth; and

5. Long, straight stems.

Asexual reproduction of this new variety by budding, as performed at Uetersen, Germany, and 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 descriptions using terminology in accordance with the Royal Horticultural Society (London) Colour chart, except where ordinary dictionary significance of color is indicated.
