Abstract

A new variety of Floribunda rose suitable for garden decoration, having flowers of orange coloration.

Description

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘U.F.O.’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Floribunda Rose variety which was originated by crossing as seed and pollen parents two unnamed, undistributed, unpatented seedlings. Among the novel characteristics possessed by the new variety which distinguish it from known other varieties is its initial attractive tight centered petals of coral coloration which transition into contrasting coral yellow or interior petals. The varietal denomination of the new rose is ‘U.F.O.’.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor is the following combination of characteristics: The plant is a bushy compact plant with upright spreading growth habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County California, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘U.F.O.’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. ‘Dr. Huey’ (unpatented).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The new variety may be distinguished from its closest commercially available cultivar, ‘Easy Living’, by the following combination of characteristics: It has a unique bloom with flowers of high coloration, with robust vigorous growth habit and bright green foliage. The new variety may be distinguished from its parent plants primarily in flower color.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph, FIG. 1, illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of two year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of October. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers singly, sometimes in clusters of four to five or more per stem. Flowers are borne in regular rounded to pyramidal clusters on strong short to medium stems. Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a slight fruity fragrance.

BUD

The peduncle is about 3.1 cm to about 5.1 cm in length, of slender to average caliper. The peduncle has an observed diameter of 0.3 cm to 0.5 cm, with typical diameter of 0.4 cm. It is usually smooth, with some stipitate glands, and some hairs and prickles. Peduncle color is near between 144a and 148b. Before the calyx breaks, the bud is about 1.1 cm to about 2.1 cm in diameter at the widest point, about 1.3 cm to about 2.6 cm in length, and ovoid to globular in shape with a conspicuous neck. The surface of the bud bears some foliaceous appendages, stipitate glands and glandular bloom, usually with slender cut bristle-like foliaceous parts extending beyond the tip of the bud about ½ or more of its length. Bud color is near between 144a and 138a.

The sepals are about 2.7 cm to about 4.1 cm in length and about 1 cm to about 1.4 cm in width at the widest point. Sepal apex ends in elongated sharp point, about 0.1 cm wide and from 0.1 cm to 1 cm long. Observed and typical number of sepals are five. The outer surface color of the sepal is near between 144a and 138a. The inner surface color of the sepal is near between 137c and 138b. Sepal margins are lined with fine wooly tomentum, few stipitate glands and hairs.

The receptacle of the flower is of moderately short to medium length. Observed length ranges from 0.9 cm to 1.3 cm, with typical length of 1.1 cm. The observed diameter of the receptacles are 0.8 cm to 1.4 cm with typical diameter of 1.2 cm. The receptacle is globular in form. Its surface is somewhat smooth with moderately thin walls. The receptacle color is near between 144a and 138b.

As the petals open (after the calyx breaks), the bud is about 1.9 cm to about 2.7 cm in diameter at the widest point, about 3.2 cm to about 4.1 cm in length, and very moderately ovoid to globular in form. The color of the under surfaces of the newly opened petals is near between 32b 32c. The color of the upper surfaces of the newly opened petals is near between 23c-23d.

BLOOM

When fully open, the bloom ranges from about 7 cm to about 9 cm in diameter. Petalage is double with about 20 to 26 petals and about 1 to 4 petaloids irregularly arranged. When partially open, the bloom form is moderately cupped to globular, and the petals are somewhat tightly spiraled to cupped with petal edges somewhat rolled inward. When fully open, the bloom form is moderately cupped to full and globular, and the petals are somewhat tightly cupped to imbricated with petal edges moderately rolled outward.

PETALS

The substance of the petals is somewhat leathery crisp and of medium to thick thickness, with upper surfaces slightly satiny, and under surfaces slightly satiny to velvety. The petals are about 4.1 cm to about 6.2 cm in length and about 4.0 cm. to about 6.1 cm in width at the widest point. Petal margins are somewhat dentate.

The outer petals are very round in shape with apices rounded and usually slightly notched with one to two notches. At the base point where the petal attaches, there is a moderately small zone of approximately 0.5 cm of contrasting color change to near 23c-23d. The base attachment observed is from 0.2 cm to 0.4 cm wide, with typical width of 0.3 cm.

The inner petals are very broadly round in shape with apices rounded to flat and usually slightly notched with one to two notches. At the base point where the petal attaches, there is a zone of approximately 0.5 cm of slight color change of near 22c-22d. The base attachment observed is from 0.2 cm to 0.4 cm wide, with typical of 0.3 cm.

Petaloids are about 0.4 cm to about 1 cm in length and about 0.3 cm to about 0.8 cm in width at the widest point. Petaloids are shaped moderately round to cuneate with moderately rounded apices. Observed margins are smooth to slight ruffle, typically smooth; and tapering to a narrow base about 2 cm wide at the attachment. The observed texture of the petaloids surfaces are somewhat leathery crisp to very leathery crisp, typical texture being somewhat leathery crisp.
