Floribunda rose plant named ‘JACnereb’

Abstract

A floribunda rose plant characterized by its compact, well-branched but vigorous growth; its dark green, disease resistant foliage; and its large, cupped, old fashioned looking flowers having a high petal count and a strong, sweet, fruity fragrance.

Description

LATIN NAME OF GENUS AND SPECIES

Rosa hybrida.

VARIETY DENOMINATION

‘JACnereb’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing the variety ‘JACdew’, U.S. Plant Pat. No. 5,122, with the variety ‘HARrooney’, U.S. Plant Pat. No. 5,582.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the dark green disease resistant foliage and compact, vigorous plant of the female parent combined with the large flower and sweet fragrance of the male parent.

BRIEF SUMMARY OF THE INVENTION

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. Strong, sweet, fruity fragrance;

2. Compact, well-branched plant;

3. Dark green, disease resistant foliage;

4. Large, cupped, old fashioned looking flower;

5. High petal count; and

6. Vigorous growth.

Asexual reproduction of this new variety by budding on ‘Dr. Huey’ understock (unpatented), as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

‘JACdew’, the female parent, is an orange floribunda having 3½ inch flowers with a slight fragrance. The flowers having 10-15 petals per bloom. ‘HARrooney’, the male parent, is an amber-yellow floribunda with 20-30 petals having a strong fragrance, the flowers being 4-4½ inches in diameter. ‘JACnereb’ has peach-apricot colored flowers that are 4 inches in diameter and have 40-45 petals with a strong fruity fragrance.

BRIEF DESCRIPTION OF THE ILLUSTRATION

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.
