Floribunda rose plant named ‘HARgrace’

Abstract

Floribunda rose plant having excellent flower form; high production of orange flowers; and dark, glossy foliage having good resistance to mildew and rusts.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘HARgrace’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a floribunda rose plant named ‘HARgrace’ which was originated by me by crossing the variety ‘Silver Jubilee’ (not patented), with the variety ‘Dame of Sark’ (not patented).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new floribunda rose variety having well formed blooms in sprays, to increase the disease resistance with the aim of developing a low maintenance rose and to improve the number of blooms by having the re-bloom cycle as speedy as possible.

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. Flower form is excellent like its female parent.
  • 2. High flower production like the male parent.
  • 3. Great flower color which is a blend of both parents.
  • 4. Dark, glossy foliage like the female parent with the disease resistance of the male parent.

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

‘Silver Jubilee’, the female parent, is a pink blend while ‘HARgrace’ is apricot to peach color. ‘Silver Jubilee’ hides its blooms while ‘HARgrace’ holds them above the plant. ‘Silver Jubilee’ has one bloom per stem while ‘HARgrace’ has large clusters of bloom. ‘Dame of Sark’, the male parent, is a red floribunda with some yellow on the petal reverse. ‘Hargrace’ is apricot to peach in color. ‘Dame of Sark’ frequently has distorted petals while ‘HARgrace’ is symmetrical in form.

Comparison with Similar Variety

‘Hargrace’ is similar to ‘Southhampton’ (unpatented), a marmalade-orange floribunda, which is more open and taller than ‘HARgrace’. It is also similar to Easy Going (‘HARflow’) (U.S. Plant Pat. No. 10,478). Easy Going has golden-amber blooms while ‘HARgrace’ has apricot blooms. ‘HARgrace’ has larger sprays than Easy Going.

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
