| Abstract: |
A new and unique cultivar of Chrysanthemum frutescens named `Camilla Ponticelli` having white flower color with a gold-yellow disc, compact growth habit, dense branching, early natural season flowering, and the ability to be cultivated as a greenhouse or outdoor cultivar. |
| Claim: |
I claim:
1. A new and distinct cultivar of Chrysanthemum frutescens plant named `Camilla Ponticelli`, as described and illustrated. |
| Description: |
The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema frutescens, commercially known by the designation "daisy", and hereinafter referred to by the cultivar name `Camilla Ponticelli`.
`Camilla Ponticelli` was originated by the inventor Noli Giacomo in a controlled breeding program in Sanremo, Italy in 1983. The new cultivar was produced from a self-pollination of the vegetatively propagated parent cultivar `Italia`.
`Camilla Ponticelli` was discovered and selected as one flowering plant within the progeny of the stated self-pollination by the inventor in 1983 in a controlled environment in Sanremo, Italy.
The first act of asexual reproduction of `Camilla Ponticelli` was accomplished when vegetative cuttings were taken from the initial selection in 1984 in a controlled environment in Sanremo, Italy by the inventor. Although viable seeds areproduced, asexual propagation is the preferred form of propagation.
Horticultural examination of selected units initiated following propagation has demonstrated that the combination of characteristics as herein disclosed for `Camilla Ponticelli` are firmly fixed and are retained through successive generations ofasexual reproduction.
The new cultivar 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, without, however, any variation ingenotype. The following observations, measurements and comparisons describe plants grown in Sanremo, Italy under greenhouse conditions which approximate those generally used in commercial greenhouse practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of `Camilla Ponticelli`, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar:
1. A daisy pot capable of production under greenhouse of outdoor culture.
2. Compact growth habit, with numerous lateral shoots being formed which result in dense branching.
3. White ray floret color with golden yellow disc.
4. Grey-green foliage color.
5. Early natural season flowering in Sanremo, flowering in spring and through the summer.
The new cultivar is similar in several phenotypic respects to its parent, with the principal distinguishing features being the significantly more compact growth habit of `Camilla Ponticelli`, and its grey-green foliage, with `Italia` havingfoliage which is more "spinach-green" in color. The new cultivar produces many more lateral shoots which result in dense branching. In addition, `Camilla Ponticelli` flowers more uniformly and abundantly than its parent, and flowers through the springand summer. A more detailed comparison of the characteristics of `Camilla Ponticelli` and `Italia` are shown in Chart A appearing at the end of the specification.
To the inventor's best knowledge, `Camilla Ponticelli` is the first variety of Chrysanthemum frutescens in Europe to be specifically and purposely selected for the pot growing industry. All other known varieties are cut flower varieties, andonly temporarily pot grown.
The accompanying photographic drawing shows in front perspective view typical inflorescence and leaf characteristics of `Camilla Ponticelli`, with the colors being as nearly true as possible with illustrations of thistype.
In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values were taken at Sanremo, Italy.
