| Abstract: |
A new and distinct variety of Potentilla fruticosa named `Hinerob` bearing orange red flowers. |
| Claim: |
I claim:
1. A new and distinct variety of Potentilla Fruticosa substantially as herein shown and described. |
| Description: |
BACKGROUND OF THEINVENTION
Potentilla fruticosa are ornamental flowering shrubs which are relatively disease-free and possess varying flower coloration. Potentilla genus is in the rose family and may be an annual or perennial. About five hundred species have beenrecorded including many varieties of Potentilla fruticosa. All Potentilla have five-lobed leaves and flowers, with petals and sepals also in multiples of five. The flowers are attractive on the shrub but do not last well after they are picked.
SUMMARY OF THE INVENTION
This invention relates a new variety of Potentilla fruticosa that produces orange red flowers.
The new plant was discovered as a seedling in a controlled planting of the Potentilla variety `Red Ace` and is believed to be a self seedling of that variety. `Red Ace` is the subject of U.S. Plant Pat. No. 4,226. The varietal denomination ofthe new variety is `Hinerob`. Asexual reproduction of the new variety by cuttings as performed in Lusk County Dublin, Ireland, and Orange County, Calif., has confirmed that the distinguishing characteristics of the new variety are transmitted tosucceeding generations.
BRIEF DESCRIPTION OF THE ILLUSTRATIONS
The accompanying photographs show typical specimens of the new variety depicted in color as nearly true as is reasonably possible to make the same in color illustrations of this character.
FIG. 1 illustrates the orange red color of the blossom as compared to the yellow orange coloration of the blossoms of the parent variety `Red Ace`;
FIG. 2 is a closeup of a flower of the new variety; and
FIGS. 3 and 4 are illustrations of flowering plants of the new variety and of the parent variety, respectively.
COMPARISON WITH PARENT
In U.S. Plant Pat. No. 4,226 it is indicated that flowers of `Red Ace` have red coloration. However, in the Southern California climate although the initial spring flower color of both cultivars display red coloration, the flower color of `RedAce` in heat is substantially pure yellow, regardless of irrigation practices. FIG. 1 is a photograph comparing the flowers produced by `Red Ace` and the new variety in Irvine, Orange County, Calif. taken of flowers on container plants of the same age,on the same day and under the same growing conditions. In similar growing tests in Canada, it has been reported that flowers of both `Red Ace` and the new variety open red and whereas `Hinerob` may fade to orange in July and August, `Red Ace` fades toyellow. Moreover, later produced flowers of `Hinerob` remain red.
DETAILED DESCRIPTION OF THE NEW VARIETY
The following description was made from established plants grown in containers at Santa Ana, Calif. in from the south of March to June. Color descriptions are provided by reference to The Royal Horticultural Society color chart unless otherwiseindicated.
