Floribunda rose plant named ‘JACfrain’

Abstract

Floribunda rose plant with flowers having a sweet musk fragrance; vigorous upright growth, well branched; large, multicolored blooms; disease resistant foliage; petals that drop cleanly and high centered flowers.

Description

Genus and Species: Rosa hybrida.

Variety Denomination: ‘JACfrain’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a floribunda rose plant named ‘JACfrain’ which was originated by me by crossing the variety ‘AROfres’ (not patented, seed parent), with the variety ‘MACivy’ (U.S. Plant Pat. No. 8,362, pollen parent).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new floribunda rose variety having the disease resistant foliage, large flower size, high-centered form and ability to drop its petals cleanly of the female parent combined with the vigorous upright growth and sweet musk 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. Sweet musk fragrance.
  • 2. Vigorous upright growth, well branched.
  • 3. Large, multicolored blooms.
  • 4. Disease resistant foliage.
  • 5. Petals that drop cleanly.
  • 6. High centered flowers.

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

COMPARISON WITH PARENTS

‘JACfrain’ differs from ‘AROfres’ in plant habit (typically 120 cm tall for ‘JACfrain’ versus 80 cm for ‘AROfres’) and flower color (yellow, pink, orange blend for ‘JACfrain’ versus yellow for ‘AROfres’). ‘JACfrain’ differs from ‘MACivy’ in flower color (yellow, pink, orange, blend for ‘JACfrain’ versus apricot copper for ‘MACivy’).

COMPARISON WITH SIMILAR VARIETY

Although it is difficult to find a comparison variety, ‘JACtorse’ (U.S. Plant Pat. No. 12,129) is an example variety. ‘JACfrain’ differs from ‘JACtorse’ in flower color (yellow, pink, orange blend for ‘JACfrain’ versus deep pink with creamy reverse for ‘JACtorse’) and in fragrance (apple for ‘JACtrose’ versus musk for ‘JACfrain’).

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 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© 2001, except where ordinary dictionary significance of color is indicated.
