BACKGROUND OF THE INVENTION
The present invention comprises a new and distinctive chrysanthemum plant, hereinafter referred to by the cultivar name MN98-E90-15. This new cultivar was the result of a cross in 1989 between Dendranthema weyrichii andDendranthema.times.grandiflora. More specifically, the breeding program which resulted in the production of the new cultivar was carried out at St. Paul, Minn. The female or seed parent of MN98-E90-15 was Dendranthema weyrichii `Pink Bomb`,commercially available from White Flower Farms, Connecticut having the following characteristics: (a) the plant habit is prostrate and the plant spreads via rhizomes to form a large mat after the first year; (b) the plant dimensions are that the planthas a diameter of about 1.5' and is about 5-6" tall; (c) the plant is hardy in zones 4-9 (Southeast)/Zone 10 (west); (d) the flower of the plant is a single daisy, having light lavender-colored ray florets and central disc florets with yellow pollen; (e)the plant has leaves that are dark green in color, with a very shiny leaf surface (glossy), and glabrous leaf margins that are deeply incised; and (f) the plant tends to rosette, needs cold treatment to flower consistently, flowering can be sporadic withgaps in the plant architecture and the plant is an obligate short-day plant. The male or pollen parent of MN98-E90-15 was a Dendranthema.times.grandiflora which is commercially available from Yoder Brothers, Inc., Barberton, Ohio having the followingcharacteristics: (a) the plant habit is cushion; (b) the plant dimensions are that the plant is similar to other cushion types commercially available from Yoder Brothers, Inc., such as, but not limited to the variety, `Soft Cherie`; (c) the plant ishardy in zones 6-9 (Southeast)/Zone 10 (west); (d) the flower is a single or duplex daisy, possibly orange or bronze ray florets, central disc florets with yellow pollen; (e) the plant has leaves that are similar to other Yoder Brothers, Inc. cushionseries chrysanthemums; and (f) the plant is a facultative short-day plant. The resulting seed, identified as 90-287-145 was collected. In 1991, a plant of 90-287-145 was selfed, and the resulting seed, identified as 92-396-20, collected. In 1994, aplant of 92-396-20 was crossed as the male plant with plants identified as 90-275-27, a University of Minnesota variety, as the female parent, and the resulting seeds, identified as 95-331-6, collected. In 1997, plants of 95-331-6 were selfed oropen-pollinated and the resulting seeds, identified as MN98-E90-15, selected. The parentage of the new cultivar can be summarized as follows:
Asexual reproduction of the new cultivar by terminal or stem cuttings taken 1993 through 2000 at St. Paul, Minn., U.S.A. has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained throughsuccessive generations of such asexual propagation.
SUMMARY OF INVENTION
It was found that the cultivar of the present invention: (a) exhibits extreme hybrid vigor; (b) develops, in its second and subsequent years after planting, when grown in the fall under natural daylength and without the application of growthregulators, into a flowering herbaceous shrub having a plant height of from about 2.5 to about 4.0 feet and a spread from about 3.0 to about 6.0 feet; (c) exhibits, in its second and subsequent years after planting and during the fall season(August-October), a massive floral display; (d) displays flowers which are slightly toned with grey, giving the flower petals a slightly altered coloration; (d) exhibits superior winter hardiness, including frost tolerance; and (e) exhibitsself-pinching.
The MN98-E90-15 cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, andday length.
When the new cultivar of the present invention is compared to `Soft Lynn` (U.S. Plant Pat. No. 8,898), it is found to exhibit a more spreading and prolific habit accompanied with a massive floral display in its second and subsequent years afterplanting. Reference is made to Table A below which compares certain characteristics of MN98-E90-15 to `Soft Lynn`.

Each stamen is borne on a filament that, when mature (dehiscent with pollen shedding longitudinally along the long axis of the anther), places the stamens above the stigma (i.e., thetop portion of the pistil.). Pistil number.--Each ray floret possesses one pistil (there are approximately 60 per inflorescence). Likewise, each disk floret also possesses a pistil (there are approximately 191 per inflorescence). Therefore, the totalnumber of pistils/inflorescence is 251 (60+191). The size of the pistil (length) is approximately 1 cm. Disease resistance.--None Known as MN98-E90-15 has not been tested for any diseases. Seed production and fruit.--About 252 ovules/flower. Thefruit is an achene, a dry, indehiscent fruit with a single locule and a single seed, and with the seed attached to the ovary wall at a single point. The achene does not have any pappus of awns for bristles; its general shape is a half-inflated footballoval with pointed ends. Seed size is about 0.2-0.5 cm in length and about 0.1-0.2 cm in width. The surface texture is ridged. The color designation for the seed is RHS Brown Group 200D. Fragrance.--Fragrance is noticeable when handling or bruisingthe foliage. Longevity of the bloom.--Flower longevity is temperature dependent. Under normal conditions in the field, during the fall season, flowers will typically last about 2-4 plus weeks.
