Abstract: A chrysanthemum plant named `Zanmudande` characterized by its medium sized blooms with yellow ray florets and prolific branching; natural season flower August 13 (week 33) blooming for a period of 5 weeks.
Claim: I claim:

1. A new and distinct Chrysanthemum plant named `Zanmudande` as described and illustrated.
Description: Botanical designation:Chrysanthemum.times.morifolium Ramat.

Cultivar denomination: `Zanmudande`.


This new plant cultivar `Zanmudande` is related to `Zanmutang` (U.S. Plant patent application Ser. No. 13/200,328), a sibling from the same cross with parent plants.


The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination`Zanmudande`. `Zanmudande` is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new cultivars with a double type inflorescence, a natural season flower date around August 13 (week 33),blooming for a period of 5 weeks. `Zanmudande` is a seedling resulting from a cross of the female parent id 21570 with the male parent id 23262. Both parents are unpatented plants. Plants of the new cultivar `Zanmudande` differ from plants of thefemale parent in the following characteristics. (1) Plant vigor and (2) Natural season flower date. (1). Plants of the seedling are more vigorous than plants of the female parent. (2) Plants of the seedling flower earlier in the season than plants ofthe female parent. Whileas plants of the new cultivar `Zanmudande` differ from plants of the male parent in the following characteristics. (1) Plant vigour and (2) Natural season flower date. (1). Plants of the seedling are less vigorous than plantsof the male parent. (2) Plants of the seedling flower earlier in the season than plants of the male parent.

The new and distinct cultivar was discovered and selected as a flowering plant by Wilhelmus Bemardus Blom on a cultivated field in Rijsenhout, The Netherlands in 2005. The first act of asexual production of `Zanmudande` was accomplished whenvegetative cuttings from the initial selection in 2005 were propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.


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.

FIG. 3 shows the various stages of foliage of the new cultivar.


The observations and measurements were gathered from plants grown out door in Rijsenhout, The Netherlands under natural day length and temperature and planted in week 23 in 2005. The natural blooming date of this crop was August 13 (week 33). The average height of the plants was 35 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized blooms withyellow ray florets blooming for a period of 5 weeks.

From the cultivars known to inventor the most similar existing cultivar in comparison to `Zanmudande` are `Mermaid Yellow Improved` (U.S. Plant Pat. No. 18,905) and `Zanmugolmine` (U.S. Plant Pat. No. 22,618). When the three cultivars arebeing compared the following differences are noticed: (1) Inflorescence size. And (2) Color ray-florets. (1) The inflorescences of `Mermaid Yellow` are larger than those of `Zanmudande` and `Zanmugolmine`. (2) The ray florets are more dark yellow in`Zanmudande` than in `Mermaid Yellow` and `Zanmugolmine`.

The following is a description of the plant and characteristics that distinguish `Zanmudande` as a new and distinct variety.

The color designations 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. The color chart used in this description is:The Royal Horticultural Society Colour Chart, edition 2001.
