Miniature rose plant named ‘JACdandy’

Abstract

Miniature rose plant having novel lavender pink and brown flower color; compact, well-branched plant habit of growth; ease of own root rooting from soft wood cuttings; and resistance to rust and powdery mildew.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘JACdandy’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a miniature rose plant named ‘JACdandy’ which was originated by me by crossing the rose plant ‘JACbow’ (U.S. Plant Pat. No. 11,690, seed parent) with the rose plant ‘Chipmunk’ (unpatented, pollen parent).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new miniature rose variety having the vigor and own root capabilities of the female parent combined with the small flowers and foliage 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. Novel lavender pink and brown flower color.
  • 2. Compact, well-branched plant habit of growth.
  • 3. Ease of own root rooting from soft wood cuttings.
  • 4. Resistance to rust and powdery mildew.

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

‘JACdandy’ differs from the female parent ‘JACbow’ in having smaller flowers (about 7 to 7.5 cm open diameter for ‘JACbow’ versus about 4 cm open diameter for ‘JACdandy’). ‘JACdandy’ differs from the male parent ‘Chipmunk’ in being much larger (about 60-80 cm high and 60-70 cm wide when mature for ‘JACdandy’ versus about 30 cm for ‘Chipmunk’). ‘JACdandy’ also has less fragrance than ‘Chipmunk’.

COMPARISON WITH SIMILAR VARIETY

Either ‘JACbow’ (U.S. Plant Pat. No. 11,690) or ‘Chipmunk’ (unpatented) is the most similar variety to ‘JACdandy’ known to the inventor.

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 cultivator 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.

• Parentage:
  • • Seed parent.—‘JACbow’ (U.S. Plant Pat. No. 11,690).
