Chrysanthemum plant named ‘Yokristi’

#Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Yokristi.

#The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yokristi’.

#The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret coloration and good garden performance.

#The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograhs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.

#The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Yokristi’ grown in a container.

#The photograph on the second sheet comprises a close-up view of typical inflorescences of the cultivar ‘Yokristi’.

#In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Leamington, Ontario, Canada during the late summer and fall in an outdoor nursery and under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was planted in a 15.25-cm container in mid-July. During the production of the plants, plants were exposed to natural season photoperiodic conditions with day temperatures averaging 26° C. and night averaging 18° C. Measurements and numerical values represent averages for typical flowering plants. Botanical classification: Chrysanthemum×morifolium cultivar Yokristi.
