Description

Description

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmulpine’.

RELATED CULTIVARS

This new plant cultivar ‘Zanmulpine’ is of the botanical classification Chrysanthemum x morifolium Ramat.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum x morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmulpine’. ‘Zanmulpine’ 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 October 9, blooming for a period of 5 weeks. ‘Zanmulpine’ is a seedling resulting from a cross of the female parent 36979 (unpatented) with the male parent 37034 (unpatented). Plants of the new cultivar ‘Zanmulpine’ differ from plants of the female parent in the ray-floret color, ray-florets of the seedling are white, while those of female parent show some pink coloration due to anthocyanin formation at low temperatures. Plants of the new cultivar ‘Zanmulpine’ differ from plants of the male parent in the following characteristics. (1) Inflorescence color. And (2) Inflorescence size. (1) Inflorescences of the seedling are more white than those of the male parent.(2) Inflorescences of the seedling are larger than those of the male parents.

The new and distinct cultivar was discovered and selected as a flowering plant by Sjoukje Heimovaara on a cultivated field in Rijsenhout, The Netherlands in October 2012. The first act of asexual production of ‘Zanmulpine’ was accomplished when vegetative cuttings from the initial selection were propagated further in a controlled environment in Rijsenhout, the Netherlands, in December 2012. In summer, about 6-8 days are needed to initiate roots in cuttings of the new cultivar, after another 5 days rooted plants are formed. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (of about 20 weeks) is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

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

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

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants in the period of 18 to 23 weeks of age grown outdoor in Rijsenhout, the Netherlands, under natural day length and temperature and planted in week 23 in 2017, receiving drip irrigation. The natural blooming date of this crop was October 9 (week 41). 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 blooming for a period of 5 weeks.

From the cultivars known to the inventor the most similar existing cultivar in comparison to ‘Zanmulpine’ is ‘Zanmudove’ (U.S. Plant Pat. No. 24,618). When ‘Zanmudove’ and ‘Zanmulpine’ are being compared the following differences are noticed: (1). Natural season blooming date. And (2). Plant vigor. (1). Plants of ‘Zanmulpine’ flower later in the season than plant of ‘Zanmudove’. (2). Flowering plants of ‘Zanmulpine’ are larger than those of ‘Zanmudove’

The following is a description of the plant and characteristics that distinguish ‘Zanmulpine’ 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, sixth edition (2015).
