Comparison with Parent

Plants of the new Chrysanthemum variety Esperanto Happy are most similar to the parent cultivar Esperanto Improved in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety Esperanto Happy compared to plants of the parent cultivar Esperanto Improved in the following characteristics.

1. The new variety Esperanto Happy produces red/yellow striped single flowers whereas the parent cultivar Esperanto Improved produces pink/white striped single type flowers.

2. Plants of the new variety Esperanto Happy have similar inflorescence to the plants of the parent cultivar Esperanto Improved .

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety Esperanto Happy is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of February. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.

Plants of the new variety have been grown successfully under temperature conditions averaging about 18 C. at night and about 24 C. to 25 C. during the day under light conditions of about 5000 to 6000 foot candles. The plants respond well to the use of growth retardant, such as B9 treatment. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 14 cm. It has been observed that the shelf life of the new variety is about 24 days with a response time of about 8 weeks. The new variety is suitable for growth in a temperature range of 17 C. to 28 C.

The following description is with respect to a plant produced as pot Chrysanthemum . In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
