Abstract

A new and distinct Chrysanthemum plant cultivar is disclosed, characterized by having a large (10-12 cm) daisy flower form with golden yellow ray florets that have a distinctive red streaking. The floral longevity is very good, and the overall plant vigor is excellent.

Description

Latin name of the genus and species: The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum morifolium.
Variety denomination: The new and distinct Chrysanthemum plant is hereinafter referred to by the cultivar name ‘JMay02’. BACKGROUND OF THE INVENTION
The new cultivar is a discovered natural mutation. The new cultivar was discovered in a cultivated area and selected by the inventor in a controlled environment in October 2001.
Asexual reproduction of the new cultivar by cuttings was performed in San Luis Obispo, Calif. and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘JMay02’ 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 ‘JMay02’. These characteristics in combination distinguish ‘JMay02’ as a new and distinct Chrysanthemum cultivar:
1. The flowers have Golden yellow petals with red brushstroke stripes.
2. The flowers are large (10-12 cm) and of daisy flower form.
3. The plant has a strong, spreading growth habit with slightly sparse foliage.
4. The branching habit is four to six breaks per stem on a single pinch.
5. Floral longevity is very good. Flower color intensity fades with time.
6. Plants have excellent vigor and strong stems.
7. The brushstroke characteristic on ray floret petals is distinctive and very unique.
Plants of the new cultivar are similar to plants of the parent variety ‘Pelee’ (U.S. Plant Pat. No. 8,464) in most horticultural characteristics, such as growth habit, longevity, and plant vigor. However, in contrast to ‘Pelee’, plants of the new variety have a distinct flower petal color having red streaking on a yellow background.
Plants of the new cultivar are similar to plants of a comparable variety ‘Fire Island’. In constrast to ‘Fire Island’, ‘JMay02’ flower petal color is yellow with red brushstrokes or streaking. Additionally, ‘JMay02’ petals have an acute rather than obtuse tip, and the flowers also tend to reflex less than in the comparable variety ‘Fire Island’. The flower color of ‘JMay02’ fades more quickly than in ‘Fire Island’. The disc corolla is also more rounded than in ‘Fire Island’. Further, the growth habit of ‘JMay02’ is slightly less vigorous, more spreading and less upright than in ‘Fire Island’. The foliage color is lighter, more sparse, and more subdued than in ‘Fire Island’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Chrysanthemum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum; and shows a top view of a plant of ‘JMay02’ in full bloom, growing in a 6.5 inch container. Five cuttings were used in the container.
DETAILED BOTANICAL DESCRIPTION
In 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 San Luis Obispo, Calif., during Spring 2002. The plants were grown in a greenhouse with a growing temperature ranging from 65° to 70° F. at night to 70° to 75° F. during the day. The observed plants were approximately 72 days old as measured from the date of rooting of the cutting. The observed plants were first grown for 16 days with “long day” light conditions, then switched to “short day” conditions for the last 56 days. Measurements and numerical values represent averages of typical flowering types.
