Abstract

A new and distinct cultivar of Chrysanthemum plant named `Vyron`, bearing medium sized yellow blooms with a brownish center and a performance of about 14 days.

Description

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 Regoltime (not patented). The new cultivar was discovered as a whole plant mutation in 1986 in a greenhouse at 's-Gravenzande in Holland. The invention has been asexually reproduced by cuttings at the same location. The new cultivar has been found to retain all of its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of Chrysanthemum of a medium sized yellow bloom with a brownish center.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrystanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type. In this regard, the ray florets illustrated in FIG. 2 appear slightly darker and more orange than true.

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

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

FIG. 3 shows foliage and petiole of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of Chrysanthemum is of the botanical classification Dendranthema grandiflora. When grown in the vicinity of 's-Gravenzande, Holland, it has a response time of approximately 9 weeks. This new variety produces medium sized yellow blooms with a brownish center having a 2 week performance (i.e., vase life of 14 days). This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations and may be planted under greenhouse conditions in Holland between weeks 2 and 32.

The following is a description of the plant and characteristics (color designations are from R.H.S. Colour Chart) that distinguish it from related known varieties and 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.
