A chrysanthemum plant named Yellow Envy particularly characterized by its flat capitulum form, decorative capitulum type, yellow ray floret color, diameter across face of capitulum of up to 13 cm at maturity when grown as a pinched disbudded pot mum, uniform eight week photoperiodic flowering response to short days, short plant height when grown as a pinched pot mum, and spreading branching pattern.

The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar named Yellow Envy.
Yellow Envy, identified as 82-E64B07, is a product of a mutation induction program which had the objective of creating new Chrysanthemum cultivars that would expand the color range of an existing cultivar while retaining all other traits.
Yellow Envy was discovered and selected by a technician working under formulations established by Cornelis P. VandenBerg in February of 1986 in a controlled environment in Alva, Fla. as one flowering plant within a flowering block established as rooted cuttings from stock plants which had been exposed as unrooted cuttings to an X-ray source of 2000 rads. The irradiated parent was the cultivar identified as Envy, disclosed in U.S. Plant Pat. No. 5,986.
The first act of asexual reproduction of Yellow Envy was accomplished when vegetative cuttings were taken from the initial selection in April of 1986 in a controlled environment in Alva, Fla., by technicians working under formulations established by Cornelis P. VandenBerg.
Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Yellow Envy are firmly fixed and are retained through successive generations of asexual reproduction.
Yellow Envy has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and daylength.
The following observations, measurements and comparisons describe plants grown in Salinas, Calif. and Leamington, Canada, 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 Yellow Envy, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar:
1. Flat capitulum form.
2. Decorative capitulum type.
3. Yellow ray floret color.
4. Diameter across face of capitulum up to 13 cm at maturity, when grown as a pinched disbudded pot mum.
5. Uniform eight week photoperiodic flowering response to short days.
6. Short plant height, requiring 7 to 14 long days after pinch prior to short days and 1 application of 2500 ppm B-9 SP to attain a flowered plant height of 25 to 35 cm for year-round flowerings when grown as a pinched pot mum.
7. Spreading branching pattern.
The accompanying photographic drawing show typical inflorescence and leaf characteristics of Yellow Envy, with the colors being as nearly true as possible with illustrations of this type. Sheet 1 is a color photograph of Yellow Envy grown as a pinched disbudded pot mum. Sheet 2 is a black and white photograph of three views of the inflorescence of Yellow Envy. Sheet 3 is a black and white photograph showing the upper and under sides of the leaves of Yellow Envy at three stages of development (mature, intermediate and immature).
Of the commercial cultivars known to the inventor, the most similar in comparison to Yellow Envy is the parent cultivar Envy. All traits of Yellow Envy are similar to those of Envy, except the color of ray florets. Yellow Envy has a yellow ray floret color, while the color of Envy is ivory and white.
In the following description color references are made to The Royal Horticultural Society Color Chart. The color values were determined on plant material grown as a pinched disbudded pot mum in Salinas, Calif. on Apr. 3, 1989.
