Hybrid tea rose plant named `Selcarbonium`

Abstract

A new rose variety of the Hybrid Tea class, characterized by its continuous and profuse production of large cream with a pink hue flowers, borne singly on upright stems on a sturdy bush of medium height, having abundant foliage and a distinct fragrance.

Description

BACKGROUND OF THE INVENTION

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 the variety "Tineke" (U.S. Plant Pat. No. 8,055) with an unnamed (SR 85.076) and unpatented seedling. Tineke differs from "Selcarbonium" by its whiter flower color, larger petal count, longer stems, weaker fragrance, and lower flower production.

The primary objective of this breeding was to obtain a new rose variety comparable to that of "Tineke", but with a strong fragrance. While the results achieved a distinctive fragrant hybrid tea rose of large size, the new variety did not otherwise correspond to the characteristics of "Tineke", but nevertheless, achieved a new and distinct combination of characteristics which is desirable and attractive, as well as different from anything heretofore available, as evidenced by the following characteristics which are outstanding in the new variety:

(1) a large cream/very soft pink flower

(2) rapid flowering cycles

(3) distinctive fragrance

(4) a vigorous upright plant of medium height.

The foregoing characteristics and distinctions definitely differentiate the new variety from its parents, as well as from all other varieties of which I am aware, and asexual reproduction of the new variety by cuttings, grafting or tissue culture as performed in a greenhouse in De Kwakel, the Netherlands, shows that these and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The new variety of rose plant is illustrated by the accompanying photographic illustrations, of which

Sheet 1 shows a full face view of the flower and

Sheet 2 shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development. The color renditions are as nearly true as it is possible to make same in color illustrations of this character by conventional photographic procedures. In this regard, the bloom coloration depicted in Sheet 1 is notably lighter than true bloom coloration.

The following is a detailed description of this new variety, with color terminology in accordance with the Royal Horticultural Society Colour Chart (RHSCC). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart e.g. "53A" is plate "53A of the Royal Horticultural Society Colour Chart.
