| Abstract: |
A new and distinct variety of Miniature rose plant is provided which resulted as a seedling from a planned hybridization program. The new variety exhibits very long-lasting flowers of a deep red coloration which are borne on a very compact plant. The new variety is very well-adapted to greenhouse forcing as a flowering pot plant as well as to general outdoor usage. |
| Claim: |
I claim:
1. A new and distinct variety of Miniature rose plant, substantially as illustrated and described, having the following combination of characteristics:
(a) forms flowers of a medium deep red coloration which are of unusually long duration,
(b) exhibits a well-balanced, compact and vigorous growth habit which is extremely floriferous,
(c) exhibits an excellent aptitude for greenhouse forcing as a flowering pot plant, and
(d) exhibits a very good comportment when used as an outdoor garden plant. |
| Description: |
SUMMARY OF THE INVENTION
The present invention relates to a new and distinct variety of Miniature rose plant which originated as a seedling in my breeding program which was carried out in The Netherlands.
The object of my breeding program was to create a new variety of the Miniature rose class having attractive red flowers on a compact, well-balanced plant which is especially well-suited to greenhouse forcing as a flowering pot plant. Thisobjective was successfully achieved, and the new variety exhibits a combination of characteristics which distinguish it from all other varieties of the Miniature rose class of which I am aware. The new variety also was found to grow well out-of-doors inthe garden.
The following combination of characteristics is observed in the new variety:
(a) forms flowers of a medium deep red coloration which are of unusually long duration,
(b) exhibits a well-balanced, compact and vigorous growth habit which is extremely floriferous,
(c) exhibits an excellent aptitude for greenhouse forcing as a flowering pot plant, and
(d) exhibits a very good comportment when used as an outdoor garden plant.
Asexual reproduction by cuttings and grafting has been accomplished in Hazerswoude, The Netherlands, and at West Grove, Pa., USA. Succeeding propagations have shown that the unique combination of characteristics is fully established and istransmitted to successive generations.
The new variety has been named the Ruiredro variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows typical specimens of my new variety of Miniature rose plant during February as depicted in color as true as is reasonably possible to make the same in a color photograph of this nature. The specimens illustratedwere grown in a greenhouse in an artificial soilless medium at West Grove, Pa., USA. The specimens illustrated tend to exhibit a more orange-red blossom coloration near Red Group 44B of The R.H.S. Colour Chart when observed during February undergreenhouse conditions than those described hereafter by reference to The R.H.S. Colour Chart when observed during May in a greenhouse at the same location .
DETAILED DESCRIPTION
The plants hereafter were grown on their own roots in four inch pots containing an artificial soilless medium while present in a greenhouse during early May at West Grove, Pa., USA. The month of blossoming has been found to influence the blossomcoloration to some degree.
The chart utilized in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart).
