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

Floribunda rose plant characterized particularly by its constant flowering with ivory flowers having a yellow base in trusses of 3 to 5 blooms and its deep maroon new foliage that turns dark green.

Genus and species: Rosa hybrida.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant named JACbeau of the floribunda class which was originated by me by crossing the variety JACjem, U.S. Plant Pat. No. 5,001, with the variety JACdew, U.S. Plant Pat. No. 5,122.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the compact habit, profuse blooming and good disease resistance of the female parent combined with good disease resistance and well branched habit 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. Constant flowering during the growing season;

2. Resistant to powdery mildew and rust;

4. Deep maroon colored new foliage that turns dark green; and

5. Flowers produced in trusses of 3 to 5.

Asexual reproduction of this new variety by budding, 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

JACbeau is different in flower color to both parents, JACjem having medium yellow flowers, JACdew having orange-red flowers.

COMPARISON WITH SIMILAR VARIETY

JACbeau has a unique cream colored bud opening to an ivory or near white flower with a yellow base making this rose unlike any other. It is more compact than KORbin (not patented) and more cream colored than JACare, U.S. Plant Pat. No. 6,515), the two closest varieties.

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 (1966), except where ordinary dictionary significance of color is indicated.

FLOWER

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

Size. About 30 mm long when the petals start to unfurl.

Form. The bud form is long, pointed ovoid.

Color. When sepals first divide, bud color is Yellow-White Group 158B. When half blown, the upper sides of the petals are Yellow-White Group 158D; and the lower sides of the petals are Yellow-White Group 158C.

Borne. Several together in clusters of 3-5 blooms having a flat shape.

Petalage. Number of petals under normal conditions: 20-25.

Color. The upper sides of the petals are Yellow-White Group 158D. The reverse sides of the petals are Yellow-White Group 158C. The base of each petal has a small (5 mm 5 mm) Yellow Group 5D color spot on both surfaces. The major color on the upper side is Yellow-White Group 158D.

Discoloration. The general tonality at the end of the first day: No change. At the end of the third day: No change.

Apex shape. Rounded to slightly murconulate.

Persistence. Petals drop off cleanly before drying.

Age to maturity. Two years.

Petiole. Color: Green Group 137C, often with some Greyed-Purple Group 183B at the point of attachment.

Petiole rachis. Color: Green Group 137C. Underside: Rough with prickles and with some glands.

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

Quantity. On main canes from base: Ordinary. On laterals from main canes: Ordinary.

Winter hardiness: Hardy to Zone 5.
