BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of chrysanthemum plant which is a natural occurring sport of a parent chrysanthemum named Remco. Patent chrysanthemum Remco is also described in this application. The new cultivar was discovered as a whole plant mutation in 1993 by R. Noodelijk in a controlled environment (greenhouse) in Ter Aar, Holland. The first act of asexual reproduction of Remco Yellow was accomplished when vegetative cuttings were taken from the initial selection in Aug. 1993 in Ter Aar, Holland.
SUMMARY OF THE INVENTIONThe present invention is a new and distinct variety of chrysanthemum bearing medium sized blooms with yellow ray florets and a greyed-red center.
BRIEF DESCRIPTION OF THE DRAWINGSThe 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 the stem of the cultivar in full bloom.
FIG. 2 shows the various stages of bloom of the new cultivar.
FIG. 3 shows the foliage and petiole of the new cultivar.
DESCRIPTION OF THE INVENTIONThis new variety of chrysanthemum is of the botanical classification Dendranthema grandiflora. When grown in the vicinity of Ter Aar, Holland, it has a response time of approximately 8 weeks. This new variety produces medium sized blooms with yellow ray florets and a greyed-red center having a 3 week performance (i.e., vase life of 21 days). This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations. However, the phenotype may vary significantly with variations in environment such as light intensity and temperature. To show the phenotype as described Remco Yellow may be planted under greenhouse conditions in Holland without assimilation lightning between week 2 and 40. With assimilation lightning (minimum level 2500 lux) Remco Yellow may be planted year round under greenhouse conditions in Holland.
The following is a discription of the plant and characteristics (color designations are from the R.H.S. Colour Chart) that distinguish it from related known varieties and its antecedents:
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.
