Floribunda rose plant named ‘KORsuflabe’

Abstract

Floribunda rose plant having large, double flowers in large clusters; disease resistance foliage; compact, well branched plant habit; and ability to grow vigorously on its own roots.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘KORsuflabe’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a floribunda rose plant named ‘KORsuflabe’ which was originated by me by crossing the variety ‘TANeitber’ (Bernstein-Rose) (not patented), with the variety ‘JACjem’ (Sunflare), U.S. Plant Pat. No. 5,001.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the deep gold, apricot flower color and high petal count of the female parent combined with the compact spreading habit, good clustering ability and disease resistance 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. Large, double flowers in large clusters.
  • 2. Disease resistant foliage.
  • 3. Compact, well branched plant habit.
  • 4. Ability to grow vigorously on its own roots.

Asexual reproduction of this new variety by cuttings, as performed at Sparrieshoop, Germany, and 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 fron the female parent in that it has much lighter flower color, larger clusters and less scent than ‘TANeitber’ and differs from ‘JACjem’ in that ‘KORsuflabe’ has more petals, more of an apricot flower color and more scent than ‘JACjem’.

Comparison with Similar Variety

The subject variety differs with more petals, more of an apricot flower color and more scent than ‘JACjem’, the closest known variety.

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.
