Abstract

A new cultivar of Clematis plant named, ‘WIT141205’ that is characterized by its nodding, semi-double flowers that are light yellow in color tinted brownish purple at the base on outer surface of tepals with staminode centers, its long blooming habit with blooms produced from spring throughout the summer in The Netherlands, and its cold hardiness at least to U.S.D.A. Zone 5.

Description

Botanical classification: Clematis koreana var. carunculosa.

Varietal denomination: ‘WIT141205’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis koreana var. carunculosa (syn. Clematis chiisanensis, Atragene Group) and will be referred to hereafter by its cultivar name ‘WIT141205’. ‘WIT141205’ is grown as an herbaceous perennial for landscape use or as a flowering potted plant for the terrace.

‘WIT141205’ originated as a seedling that arose from seed planted from the open pollination of ‘Love Child’ (not patented) at the Inventor's nursery in Boskoop, The Netherlands in 2010. ‘WIT141205’ was selected as a single unique plant in 2011 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in Boskoop, The Netherlands in 2011. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘WIT141205’ as a unique cultivar of Clematis.

- 1. ‘WIT141205’ exhibits nodding, semi-double flowers with staminode centers.
- 2. ‘WIT141205’ exhibits flowers that are light yellow in color tinted brownish purple at the base on outer surface of tepals.
- 3. ‘WIT141205’ exhibits a long blooming habit with blooms produced from spring throughout the summer in The Netherlands.
- 4. ‘WIT141205’ exhibits cold hardiness at least to U.S.D.A. Zone 5.

The female parent of ‘WIT141205’, ‘Love Child’, differs from ‘WIT141205’ in having single yellow flowers with small spots of brown or purple, and in producing seed. ‘WIT141205’ can also be compared to the Clematis cultivar ‘Lemon Bells’ (not patented). ‘Lemon Bells’ is similar to ‘WIT141205’ in having nodding flowers that are yellow in color. ‘Lemon Bells’ differs from ‘WIT141205’ in having single flowers, in having stems that are dark purple in color, and in having ternate leaves with single un-lobed leaflets.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Clematis. The photographs were taken of a two year-old plant of ‘WIT141205’ as grown outdoors in a 4.5-liter container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of the plant habit of ‘WIT141205’.

The photograph in FIG. 2 provides a close-up view of a flower of ‘WIT141205’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘WIT141205’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Clematis.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of two year-old plants of Clematis ‘WIT141205’ as grown outdoors in 4.5-liter containers in Boskoop, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic and cultural conditions, as the cultivar has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Color Chart, London, England, except where general color terms of ordinary dictionary significance are used.
