The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthema grandiflora and hereinafter referred to by the cultivar name Honey Yolima. The plant is being marketed under the name Honey Lima.
The new Chrysanthemum is a product of a mutation induction breeding program conducted by the inventor in Fort Myers, Fla. and Salinas, Calif. The objective of the program is to create new Chrysanthemum cultivars with desirable inflorescence form and floret colors, good substance, and excellent post-production longevity.
The new Chrysanthemum originated by exposing unrooted cuttings of the Chrysanthemum cultivar Yolima (copending U.S. Plant Patent Application Ser. No. 09/112,201) to X-ray radiation at a level of 2,000 rads in October, 1994, in Fort Myers, Fla. Following the radiation treatment, the cuttings were rooted and terminal apices were removed (pinched) three times to promote lateral branch development. After lateral branches from the third pinch reached sufficient size, terminal cuttings were harvested, planted and flowered in a controlled environment in Salinas, Calif. The new Chrysanthemum was discovered and selected by the inventor as a single flowering plant within this population in March, 1995. The selection of this plant was based on its desirable inflorescence form and floret colors and excellent post-production longevity.
Asexual reproduction of the new Chrysanthemum by terminal cuttings harvested in a controlled environment in Salinas, Calif., has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe cultivar Honey Yolima has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Honey Yolima`. These characteristics in combination distinguish `Honey Yolima` as a new and distinct Chrysanthemum.
1. Compact and uniformly mounded plant habit.
2. Freely branching habit, dense plants.
3. Attractive foliage to floret color contrast.
4. Uniform and early flowering.
5. Anemone spray-type inflorescences that are about 5.6 cm in diameter.
6. Attractive bronze-colored ray florets and golden yellow-tipped disc florets.
7. Numerous inflorescences per plant.
8. Excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for about four weeks in an interior environment.
Plants of the new Chrysanthemum are similar to plants of the parent cultivar, `Yolima`, and a sibling cultivar, `Purple Yolima` (U.S. Plant Patent application Ser. No. 09/112,332, filed concurrently with this application) in most horticultural characteristics, however plants of the new Chrysanthemum differ from plants of both these cultivars primarily in ray floret color.
The new Chrysanthemum can be compared to the Chrysanthemum cultivar Bronze Papillon (disclosed in U.S. Plant Pat. No. 9,824). However in side-by-side comparisons in Salinas, Calif., and Leamington, Ontario, Canada, under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Bronze Papillon in the following characteristics:
1. Plants of the new Chrysanthemum have larger leaves than plants of the cultivar Bronze Papillon.
2. Plants of the new Chrysanthemum have anemone-type inflorescences whereas plants of the cultivar Bronze Papillon have single-type inflorescences.
3. Plants of the new Chrysanthemum have larger inflorescences than plants of the cultivar Bronze Papillon.
4. Plants of the new Chrysanthemum have longer and more narrow ray florets than plants of the cultivar Bronze Papillon.
5. Disc florets of plants of the new Chrysanthemum have significantly less pollen than plants of the cultivar Bronze Papillon.

DETAILED BOTANICAL DESCRIPTIONIn the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Salinas, Calif., and Leamington, Ontario, Canada, under greenhouse conditions which approximate those generally used in commercial potted Chrysanthemum production. Four unrooted cuttings were directly stuck in a 15-cm container and pinched once. Measurements and numerical values represent averages of typical flowering plants.
Botanical classification: Dendranthema grandiflora cultivar Honey Yolima.
Commercial classification: Anemone spray-type pot chrysanthemum.
