Miniature rose plant--Wildak variety
A new and distinct variety of Miniature rose plant is provided having highly attractive double flowers which exhibit a blend of orange and yellow tones. The new variety resulted from the crossing of the Zorina variety (U.S. Plant Pat. No. 2,321) and the Starina variety (U.S. Plant Pat. No. 2,646). The buds of the new variety are perfectly formed and blossom into gracefully shaped blooms of approximately one and one-half inches. The variety also forces well and performs well outdoors.
Latest The Conard-Pyle Company Patents:
The object of the present invention is to provide a new variety of rose plant of the Miniature Class which is distinguished from prior varieties by the following combination of characteristics:
(a) from the physical standpoint the plant with medium green adult wood has a semi-erect growth habit, forms dark green glossy leaves, and forms double flowers which exhibit a blend of orange and yellow tones with a pinkish accent at the flower center; and
(b) from the biological standpoint the plant has vigorous and regular vegetation, exhibits an abundant and repeated florescence, exhibits the ability to grow well in the greenhouse or outside, possesses the ability for its blossoms to last for a long time, and forms petals which detach cleanly.
In view of these characteristics the new variety meets the needs of the horticultural industry and is particularly suited for ornamental use in gardens and forcing as a pot plant.
The new variety resulted from artificial pollination with the variety Zorina (U.S. Plant Pat. 2,321) serving as the seed parent, and the variety Starina (U.S. Plant Pat. No. 2,646) serving as the pollen parent.
The characteristics and properties of this new variety have been found to be transmissible by vegetative propagation through softwood cuttings, grafting and budding performed at West Grove, Pa.
The rose plant of the new variety has been named the Wildak variety. Plants of this new variety presently are being marketed by the Conard-Pyle Co. of West Grove, Pa. under the AMBER FLASH trademark and are members of a family of Miniature rose plants which presently are being marketed by such company under the MINIFLORA trademark.
BRIEF DESCRIPTION OF THE PHOTOGRAPHSThe accompanying photographs show as nearly true as it is possible to make the same in color illustrations of this character, typical specimens of plant parts from two year old plants produced from softwood cuttings and growing in the open air during mid-June at West Grove, Pa.
In FIG. 1 are shown blossoms of the new variety in various stages of opening.
In FIG. 2 are shown various plant parts of the new variety. In the far left portion of the photograph is shown foliage and a cluster of buds in different stages of development wherein in some instances the sepals have begun to open. In the upper left center portion of the photograph is shown a segment of a main branch. In the upper center portion of the photograph is shown a segment of a flowering stem. In the right portion of the photograph are shown blossoms in various stages of opening. In the middle lower right portion of the photograph is shown a bud immediately following the opening of the sepals. In the lower portion of the photograph are shown a leaf with five leaflets (center) and a leaf with three leaflets (far right).
