PP29467
Classification: The present invention relates to a new Rosa hybrida plant.
Variety denomination: The new plant has the varietal denomination ‘WEKfawibyblu’.
This invention relates to a new and distinct variety of Floribunda Rose. It has a non-disseminated seedling of my creation as its seed parent with the following genetic origin (seedling X Wild Blue Yonder) and as its pollen parent the variety known as ‘PEJamblu’ (U.S. Plant Pat. No. 20,325).
Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combinations of characteristics: its abundant blooms, its moderate clove with hints of cinnamon fragrance, its large clusters with multiple flowers and its several small prickles on the branches and new shoots. The plant has an upright moderately spreading growing habit, suitable for outdoor garden decoration.
Asexual reproduction of the new variety by budding as performed in Kern County and Pomona, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKfawibyblu’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. ‘Dr. Huey’ (not patented).
The new rose may be distinguished from its seed parent, a non-disseminated seedling of my creation by the following combination of characteristics: whereas ‘WEKfawibyblu’ bears double flowers (about 20 to 30 petals) of fuchsia pink with lighter reverse coloration, the non-disseminated seedling bears very double flowers of lavender coloration with significantly heavier petalage (about 35 to 52 petals). The new variety has an upright moderately spreading medium height growing habit (about 130 to about 180 cm. in height), whereas the seed parent has a rounded bushy significantly shorter growing habit (about 100 to about 120 cm. in height).
The new variety may be distinguished from its pollen parent, ‘PEJamblu’ by the following combination of characteristics: whereas ‘WEKfawibyblu’ bears double flowers (about 20 to 30 petals) of fuchsia pink with lighter reverse coloration, ‘PEJamblu’ bears semi-double flowers of mauve-lilac ageing to slate blue coloration with significantly lesser petalage (about 12 to 16 petals). The new variety has a moderate clove with hints of cinnamon fragrance, whereas the pollen parent has a very strong citrus fragrance.
The new variety may be distinguished from its closest commercially available cultivar, ‘PRObril’ (U.S. Plant Pat. No. 12,645) by the following combination of characteristics: whereas ‘WEKfawibyblu’ bears double flowers (about 20 to 30 petals) of fuchsia pink with lighter reverse coloration, ‘PRObril’ bears double flowers of deep pink and cream coloration with heavier petalage (about 27 to 32 petals). The new variety has an upright moderately spreading medium height growing habit (about 130 to about 180 cm. in height), whereas the closest commercially available cultivar has a bushy upright significantly shorter growing habit (about 75 to about 90 cm. in height).
The accompanying photograph 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. The branches used for the photograph came from 3 to 4 year-old rose plants of the new variety grown outdoors in Pomona, Calif. in the month of November. 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.
The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Pomona, Calif. in the month of November. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.
The new variety sometimes bears its flowers singly, usually in clusters of two to twenty-eight or more per stem. Flowers may be borne in rounded clusters on strong medium to somewhat long length stems (about 18 to about 115 cm.). The cluster ranges from about 9.2 to about 27.5 cm. in diameter. Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a moderate clove with hints of cinnamon fragrance.
The peduncle is about 2.3 to about 4.1 cm. in length, of average caliper (about 0.2 to about 0.3 cm. in diameter), and usually erect to somewhat stiff. It is moderately rough, with some stipitate glands, few hairs and occasionally few small prickles. Peduncle color is between 144A and 146B sometimes moderately suffused, especially on the side exposed to the sun, with between 187C and 187D.
Before the calyx breaks, the bud is about 0.9 to about 1.5 cm. in diameter at the widest point, about 1.2 to about 2.0 cm. in length, and pointed to somewhat ovoid in shape. The surface of the bud bears between 4 to 6 foliaceous appendages, some stipitate glands and hairs, usually with slender entire foliaceous parts extending beyond the tip of the bud about ¼ or more of its length. Bud color is between 146B and 137D sometimes moderately suffused, especially on the side exposed to the sun, with between 187B and 187A.
The sepals are about 1.9 to about 2.8 cm. in length and about 0.7 to about 1.0 cm. in width at the widest point. The outer surface color of the sepal is between 146B and 137D sometimes moderately suffused, especially on the side exposed to the sun, with between 187B and 187A. The outer surface of the sepal is moderately rough and bears between 0 to 3 foliaceous appendages with some stipitate glands and hairs. The inner surface color of the sepal is near 146D broadly bordered by near 138A. After the sepals open, the inner surface color is sometimes moderately suffused, especially on the area exposed to the sun, with between 187B and 187A. The inner surface of the sepal is covered with fine wooly tomentum; sepal margins are lined with some stipitate glands and hairs.
The receptacle of the flower is of moderately long length (about 0.6 to about 0.8 cm.) and average to somewhat heavy in caliper (about 0.6 to about 0.8 cm. in diameter). The receptacle is urn-shaped in form. Its surface is smooth with few hairs and with thin fleshy walls. The receptacle color is between 137C and 137D.
As the petals open (after the calyx breaks), the bud is about 1.4 to about 2.2 cm. in diameter at the widest point, about 1.6 to about 2.9 cm. in length, and moderately globular to somewhat ovoid in form. The color of the under surfaces of the newly opened petals is between 159D and 158C moderately suffused with between 60C and 64B to as dark as between 61A and 60B mostly toward the edge of the petal, sometimes moderately streaked with near 187B in the middle of the petal. At the point where the petal attaches, there is a large zone of between 154D and 1D. The color of the upper surfaces of the newly opened petals is between 60B and 60C often moderately suffused with between 187B and 187A. At the point where the petal attaches, there is a large zone of between 154D and 1D.
When fully open, the bloom ranges from about 6.4 to about 10.4 cm. in diameter. Petalage is double with about 20 to 30 petals and about 3 to 10 petaloids irregularly arranged. When partially open, the bloom form is moderately ovoid to somewhat high centered to cupped, and the petals are loosely spiraled to cupped to somewhat undulated with petal edges somewhat reflexed outward. When fully open, the bloom form is more cupped, and the petals are loosely cupped to somewhat undulated with petal edges somewhat reflexed outward.
The substance of the petals is moderately heavy and of somewhat thin to medium thickness, with upper surfaces moderately satiny and under surfaces slightly shiny to almost matte. The petals are about 3.5 to about 5.2 cm. in length and about 2.5 to about 4.6 cm. in width at the widest point. Petal margins are entire.
The outer petals are broadly obovate in shape with rounded apices.
