| Abstract: |
A new and distinct variety of Miniature rose plant is provided having attractive and very abundant blossoms which are Spinel red in coloration. The new variety resulted from the crossing of the Pinafore variety (U.S. Plant Pat. No. 1,810) and the unnamed seedling resulting from the cross of the Lilibet variety (U.S. Plant Pat. No. 1,209) and the Fairy Queen variety (non-patented). It is a very vigorous grower with a low-growing semi-spreading habit. The blossoms are single and petite and are borne in clusters of up to a dozen or more. The new variety is particularly suited for ornamental use in the home landscape. |
| Claim: |
I claim:
1. A new and distinct variety of Miniature rose plant, substantially as illustrated and described, wherein:
(a) from the physical standpoint the plant with light green wood has a semi-spreading growth habit, forms abundant shiny leaves, and forms very abundant single flowers which are Spinel red in coloration; and
(b) from the biological standpoint the plant has vigorous, low growing and regular vegetation, exhibits an abundant and repeated florescence, and forms petals which detach cleanly. |
| Description: |
SUMMARY OF THE INVENTION
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 light green wood has a semi-spreading growth habit, forms abundant shiny leaves, and forms very abundant single flowers which are Spinel red in coloration; and
(b) from the biological standpoint the plant has vigorous, low growing and regular vegetation, exhibits abundant and repeated florescence, and forms petals which detach cleanly.
The single nature of the blossoms gives them a pink dogwood-like appearance.
In view of these characteristics the new variety meets the needs of the horticultural industry and is particularly suited for ornamental use in the home landscape.
The new variety resulted from artificial pollination with the variety Pinafore (U.S. Plant Pat. No. 1,810) serving as seed parent, and an unnamed seedling as pollen parent which resulted from the crossing of the variety Lilibet (U.S. PlantPat. No. 1,209) and the variety Fairy Queen (non-patented).
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 Wilsma variety. Plants of the new variety presently are being marketed by the Conard-Pyle Co. of West Grove, Pa., under the ASTRA trademark and are members of a family of Miniature roseplants which presently are being marketed by such company under the MINIFLORA trademark.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows as nearly true as it is possible to make the same in a color illustration of this character, typical specimens of plant parts from two year old plants produced from softwood cuttings and growing on their ownroots in the open air during mid-June at West Grove, Pa.
In the left portion of the photograph is shown a specimen of foliage and clusters of buds wherein the sepals have opened on some of the buds, and the upper and lower surfaces of the leaflets are visible.
In the upper center and upper right portions of the photograph are shown fully opened blossoms and a bud.
In the far right portion of the photograph is shown a segment of branch.
In the lower right center of the photograph are shown two leaves of five leaflets each.
