Floribunda rose plant named ‘JACoutra’

Abstract

Floribunda rose plant having very large flowers in small clusters, a very compact, well-branched plant habit; glossy, dark green foliage, distinctive fruity fragrance and excellent resistance to rust and powdery mildew.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘JACoutra’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a floribunda rose plant named ‘JACoutra’ which was originated by me by crossing the variety ‘JACimpac’ (female parent, not patented), with the variety ‘JACzap’ (male parent, Plant Pat. No. 12,073).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new floribunda rose variety having the compact free flowering qualities of the female (seed) parent combined with the large flowers of the male (pollen) 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. Very large flowers in small clusters.
  • 2. Very compact, well-branched plant habit.
  • 3. Glossy, dark green foliage.
  • 4. Excellent resistance to rust and powdery mildew.
  • 5. Distinctive fruity fragrance.

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

‘JACimpac’ differs in flower color (light apricot for ‘JACimpac’ versus orange for ‘JACoutra’). ‘JACzap’ differs in flower color from ‘JACoutra’ (coral orange with yellow reverse for ‘JACzap’ versus orange for ‘JACoutra’).

COMPARISON WITH SIMILAR VARIETY

The closest variety is believed to be ‘MACtrum’ (Plant Pat. No. 4,297). ‘JACoutra’ has much larger flowers (less than 4 inches for ‘MACtrum’ and as large as 5 inches for ‘JACoutra’.

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.
