Miniature rose plant named ‘JACseboy’

Abstract

Miniature rose plant having very compact but spreading plant habit, blooming constantly in clusters, easily propagated by softwood cuttings and small, disease resistant foliage.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘JACseboy’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a miniature rose plant named ‘JACseboy’ which was originated by me by crossing an unnamed white shrub rose (not patented) (‘POULcat’ (not patented)בPOULcov’ (PP10648), with ‘DICrevival’ (PP8614).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new miniature rose variety having the large flower clusters, excellent disease resistance and compact habit of the female parent combined with the bright pink flower color and higher petal count 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. Very compact but spreading plant habit.
  • 2. Blooms constantly in clusters.
  • 3. Ease of propagation by softwood cuttings.
  • 4. Small, disease resistant foliage.

Asexual reproduction of this new variety by cuttings, as performed at Wasco and Somis, 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

‘JACseboy’ has light red to red versus white flowers, ten to fifteen versus five petals and a more spreading habit compared to the female parent. Compared to the male parent, ‘JACseboy’ is much more compact in habit, has smaller and much more numerous flowers.

COMPARISON WITH SIMILAR VARIETY

The closest variety is ‘The Fairy’. ‘JACseboy’ differs in being more compact in habit, having smaller flowers with fewer petals but similar foliage, disease resistance and flower color.

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.
