Description

BACKGROUND OF THE INVENTION

The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant that is a cross of unknown Dendranthema grandiflora parents. The new and distinct cultivar was a seedling resulting from the open pollination among groups of chrysanthemum cultivars maintained under the control of the inventor for breeding purposes. The new and distinct cultivar was discovered and selected as one flowering plant by Rob Noodelijk on a cultivated field in Rijsenhout, Holland in August 1996. The plant has been asexually reproduced by cuttings in greenhouses at Rijsenhout, Holland. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of chrysanthemum of a medium sized bloom and white color.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classification Dendranthema grandiflora.

The observations and measurements were gathered from plants grown outdoors in Rijsenhout, Holland under natural day length and temperature and planted week 22 in 1997 and 1998. The natural blooming date of this crop was August 24-25 (week 34). The average height of the plants was 25 to 28 cms. This new variety produces medium sized blooms with white ray florets and a light yellow to almost white center blooming for a period of 7 weeks. The following is a description of the plant and characteristics that distinguish Odysseus as a new and distinct variety. The color designations (color designations are from the R.H.S. Colour Chart) are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances.

Of the commercial varieties known to inventor most similar to Odysseus are the varieties Encore, described in U.S. Plant Pat. No. 6,402 and Nicole, described in U.S. Plant Pat. No. 7,517. Odysseus has a much more mounding and prolific branching pattern than either Encore or Nicole. In addition, the flower form and size of Odysseus are different from the flower form and size of Encore and Nicole.
