Chrysanthemum plant named ‘Magnus Violet’

#Botanical designation: Chrysanthemum×morifolium.

#Cultivar denomination: ‘MAGNUS VIOLET’.

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

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

#The photograph comprises a side perspective view of a typical flowering plant of ‘Magnus Violet’ grown in a container.

#The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers during the late summer and early autumn in an outdoor nursery in Oostnieuwkerke, Belgium and under cultural practices which approximate those generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° C. Plants were 20 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
