USPP19510P2 - Floribunda rose plant named ‘Jacrepin’ - Google Patents

Abstract

Floribunda rose plant having very glossy, dark green foliage, ease of own root propagation; vigorous growth on its own roots; rounded, well branched habit of growth; and flowers presented in clusters.

Description

Genus and species: Rosa hybrida.

Variety Denomination: ‘JACrepin’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a floribunda rose plant named ‘JACrepin’, which was originated by me by crossing the variety ‘JACimpac’ (not patented, seed parent), with the variety ‘JACtorse’ (U.S. Plant Pat. No. 12,129, pollen parent). The parentage of the seed parent is ‘JACdew’ (U.S. Plant Pat. No. 5,122)בHARrooney’ (U.S. Plant Pat. No. 5,582).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new floribunda rose variety having the rounded plant habit, flower clusters and glossy foliage of the coral colored floribunda female (seed) parent combined with the vigorous growth, own root ease of propagation and growth and good flower form 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 glossy, dark green foliage.
  • 2. Ease of own root propagation.
  • 3. Vigorous growth on its own roots.
  • 4. Rounded, well branched habit of growth.
  • 5. Flowers presented in clusters.

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

‘JACrepin’ differs in flower color from the flower color of the female parent (coral) and the flower color of the male parent (deep pink with light yellow petal reverse).

COMPARISON WITH SIMILAR VARIETY

The closest variety known to the inventor is ‘JACzibwo’ (U.S. Plant Pat. No. 14,245). ‘JACrepin’ differs from ‘JACzibwo’ in flower form (high centered from ‘JACrepin’ versus quite flat for ‘JACzibwo’) and in petal count (‘JACrepin’ typically having 20 to 25 petals versus typically 15 to 20 petals for ‘JACzibwo’.

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
