Floribunda rose plant named &#8216;Jaczibwo&#8217;

Floribunda rose plant having large showy clusters of bright red flowers; free flowering with rapid repeat bloom; dark green, healthy foliage resistant to rust, powdery midlew and blackspot; and vigorous, upright branching growth.

Genus and species: Rosa hybrida.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing the variety Showbiz (U.S. Plant Pat. No. 4,844) with an unnamed seedling (unpatented).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the bright red flower color, vigorous groth and healthy foliage of the male parent combined with the large flower truss and free flowering habit of the female 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:

3. Free flowering with rapid repeat bloom;

4. Dark green, healthy foliage resistant to rust, powdery mildew and blackspot; and

Asexual reproduction of this new variety by budding on Dr. Huey rootstock, 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

Larger plant than Showbiz with larger foliage. More flowers than the unnamed red floribunda seedling with faster rebloom.

COMPARISON WITH SIMILAR VARIETY

More bloom, excellent repeat bloom and more vigorous than other red floribundas presently on the market that are known to the inventor.

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, except where ordinary dictionary significance of color is indicated.

FLOWER

Observations made from plants of two years of age grown in a garden environment at Somis, Calif., January, 2000-May, 2001.

Size. About 22-24 mm long and 15-18 mm in diameter when the petals start to unfurl.

Form. The bud form is pointed ovoid.

Color. When sepals first divide, bud color is Red Group 46A. When half blown, the upper sides of the petals are Red Group 45A; and the lower sides of the petals are Red Group 45A.

Borne. In flat clusters of 4-7 blooms.

Form. When first open: Bloom is flat with a loose open form. Permanence: Retains its form to the end.

Petalage. Number of petals under normal conditions: 15-20.

Color. The upper sides of the petals are Red Group 45A. The reverse sides of the petals are Red Group 53B. The base of each petal is Red Group 55C. The major color on the upper side is Red Group 45A.

Discoloration. The general tonality at the end of the first day: Red Group 45A. At the end of the third day: Red Group 45A. By day seven, the outer color of the petals changes to Red-Purple Group 63A.

Arrangement. Informal. Petaloids in the center are few (2-3). Petaloid Color: Red Group 45A with prominent vein of Yellow-White Group 158D.

Persistence. Petals drop off cleanly before drying.

Lastingness. On the plant: Long (about 8-9 days). As a cut flower: Not tested.

PLANT

Foliage: Number of leaflets on normal mid-stem leaves: 5-7.

Disease resistance. Resistant to mildew, blackspot and rust under normal growing conditions.

Quantity. On main canes from base: 16-18 per 15 cm of stem length. On laterals from main canes: 16-18 per 15 cm of stem length.

Winter hardiness: Hardy to Zone 5.
