Floribunda rose plant named ‘Jacnewpu’

Abstract

Floribunda rose plant having novel tan and pink flowers that age increasinly pink; strong citrus fragrance; flowers presented in clusters; vigorous growth; and dark, glossy, green foliage.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘JACnewpu’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of floribunda rose plant named ‘JACnewpu’ which was originated by me by crossing the variety ‘MACnewye,’ U.S. Plant Pat. No. 5,428, with the variety ‘KEIbian,’ U.S. Plant Pat. No. 8,476.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the glossy foliage, flower clusters and vigor of the female parent combined with the strong 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. Novel tan and pink flowers that age increasingly pink;

2. Strong citrus fragrance;

3. Flowers presented in clusters;

4. Vigorous growth; and

5. Dark glossy green foliage.

Asexual reproduction of this new variety by budding, 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

The subject variety differs from the female parent in flower color, scent and petal count and differs from the male parent in flower color, flower size, growth habit and petal count.

COMPARISON WITH SIMILAR VARIETY

There is no other rose variety of which I am aware that has the old fashioned form, fragrance and novel flower color of ‘JACnewpu.’

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.

DETAILED BOTANICAL DESCRIPTION

The reverse sides of the petals are Red-Purple Group 63D with streaks of Yellow Group 4D and a margin of Yellow Group 4D around the lower half of the petal. The base of each petal has an area approximately 5 mm×8 mm of Yellow Group 4B. The major color on the upper side is Red Group 54C.

Variegations.—Occasional yellow streaks on the upper and lower surface of the petals.
