Abstract

A new cultivar of hybrid Clematis, ‘Taiga’, characterized by its large, double flowers, its purple flowers with the tips of the outer tepaloids uniquely colored light yellow-green with center tepaloids light yellow-green, and its sterile flowers with no reproductive organs present.

Description

Botanical classification: Clematis hybrid.

Variety denomination: ‘Taiga’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis, botanically of hybrid origin, and will be referred to hereafter by its cultivar name ‘Taiga’. ‘Taiga’ is grown as an herbaceous perennial for landscape use or as a terrace pot plant.

‘Taiga’ was derived from a breeding program conducted by the Inventor in Tokyo, Japan. The Inventor, now deceased, made years of crosses between plants of Clematis florida (and other species now included in the Florida group of Clematis) and plants of Clematis integrifolia, and proprietary hybrids between them. The parental plants were unnamed and unpatented, however the Inventor's records could not be found for detailed information in regards to the parents. ‘Taiga’ was selected by the Inventor as a single unique plant from a batch of seedlings in 2000.

Asexual propagation of the new cultivar was first accomplished by internodial stem cuttings by the Inventor in Tokyo, Japan in 2000. Asexual propagation by internodial 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 as grown outdoors. These attributes in combination distinguish ‘Taiga’ as a unique cultivar of Clematis.

- 1. ‘Taiga’ exhibits large, double flowers.
- 2. ‘Taiga’ exhibits purple flowers with the tips of the outer tepaloids uniquely colored light yellow-green with center tepaloids light yellow-green.
- 3. ‘Taiga’ exhibits sterile flowers with no reproductive organs present.

‘Taiga’ can be most closely compared to the Clematis cultivars ‘Vyvyan Pennell’ (not patented) and ‘Multi Blue’ (not patented). Both are similar to ‘Taiga’ in having large double purple flowers. ‘Vyvyan Pennell’ differs from ‘Taiga’ in having petaloids that lack light yellow-green tips and are tinged rose in color and in having some reproductive organs. ‘Multi Blue’ differs in having tepaloids that are tinged with silver.

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 the new cultivar as grown in a greenhouse in a 17-cm container in Aalsmeer, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘Taiga’ in bloom.

FIG. 2 provides a close-up view of the inflorescences of ‘Taiga’.

FIG. 3 provides a close-up view of the foliage of ‘Taiga’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Clematis.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of two year-old plants of ‘Taiga’ as grown in a greenhouse in 17-cm containers in Aalsmeer, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
