| Abstract: |
A new and distinct Dahlia plant named Margaret, having bright yellow flower color, double flower form, dense foliage, continuous flowering, compact flower bouquet carried above the foliage, compact growth habit, and an adaptability to pot plant or natural outdoor cultures. |
| Claim: |
I claim:
1. A new and distinct cultivar of Dahlia plant named Margaret, as illustrated and described. |
| Description: |
The present invention relates toa new and distinct cultivar of Dahlia plant known by the cultivar name Margaret, and botanically known as Dahlia cav.
Margaret is a sport or mutation of a plant of the commercially well-known seed varieties of Dahlia marketed under the name Figaro. The sport was discovered by applicant in March, 1982 in Enkhuizen, The Netherlands.
The first act of asexual reproduction of Margaret was accomplished when tuberous divisions were taken by me from the new cultivar after discovery in a controlled environment in Enkhuizen, The Netherlands. Subsequent horticultural examination ofselected units has demonstrated that the combination of characteristics as herein disclosed for Margaret are firmly fixed and are retained through successive generations of asexual reproduction.
Margaret has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length. The following observations, measurements andcomparisons describe plants grown in Enkhuizen, The Netherlands under greenhouse and outdoor conditions which approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Margaret, which in combination distinguish this Dahlia as a new and distinct cultivar:
(1) Intense, bright yellow ray floret color.
(2) Double flower form.
(3) Dense foliage.
(4) Continuous flowering, with the flowers being carried above the foliage in a compact bouquet.
(5) Compact growth habit.
(6) Adaptable to pot plant culture as well as natural outdoor growth.
Relevant cultivars for comparison purposes are the seed varieties marketed under the name Rigoletto, and the varieties of Figaro. In comparison to Rigoletto, Margaret is more compact, has a double flower form, and a more intense yellow rayfloret color. Margaret is distinguished from Figaro by its more compact habit, its earlier flowering, and the purity of its yellow ray floret color.
The accompanying color photographic drawing shows typical inflorescence and foliagecharacteristics of Margaret, with colors being as nearly true as possible with illustrations of this type. The photograph is a perspective view of several potted plants of Margaret.
In the following description color references are made to TheRoyal Horticultural Society Colour Chart. The color values were determined at Enkhuizen, The Netherlands, and the characteristics noted below are based on plants grown at the same location.
