Botanical designation: Chrysanthemum×morifolium Ramat.
Cultivar denomination: ‘Zanmubutter’.
This new plant cultivar ‘Zanmubutter’ is of the botanical classification Chrysanthemum×morifolium Ramat.
The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmubutter’. ‘Zanmubutter’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new cultivars with a double type inflorescence, a natural season flowering date around September 15, blooming for a period of about 4 to 5 weeks.
‘Zanmubutter’ is a seedling resulting from a cross of the female parent 17502 with the male parent 26356. Plants of the new cultivar ‘Zanmubutter’ differ from plants of the parents in ray-floret color. Ray-florets of plants of the seedling are white to cream colored, while those of the female parent are yellow, and those of the male parent are pure white.
The new and distinct cultivar was discovered and selected as a flowering plant by Henricus Cornelius Maria Jacobs on a cultivated field in Rijsenhout, The Netherlands in 2010. The first act of asexual production of ‘Zanmubutter’ was accomplished when vegetative cuttings from the initial selection in 2010 were propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.
The present invention of a new and distinct variety of chrysanthemum (of about 16 weeks) is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.
The observations and measurements were gathered from plants grown out door in Rijsenhout, The Netherlands, under natural day length and temperature and planted in week 25 in 2014, receiving drip irrigation. The natural blooming date of this crop was September 22. The average height of the plants was 40 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized blooms with white ray florets and a cream center blooming for a period of about 4 to 5 weeks.
From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmubutter’ is ‘Zanmuglow’ (U.S. Plant Pat. No. 22,617). When ‘Zanmuglow’ and ‘Zanmubutter’ are being compared the following difference is noticed: The difference of ‘Zanmuglow’ and ‘Zanmubutter’ are (1) Plant vigour. And (2) Natural season blooming date. (1) Plants of ‘Zanmubutter’ are larger than those of “Zanmuglow’. (2) Plants of ‘Zamubutter’ flower later in the season than those of ‘Zanmuglow’.
The following is a description of the plant and characteristics that distinguish ‘Zanmubutter’ as a new and distinct variety.
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. The color chart used in this description is: The Royal Horticultural Society Colour Chart, edition 2001.
