USPP31349P2 - Clematis plant named ‘Zo12220’ - Google Patents

Abstract

A new cultivar of hybrid Clematis, ‘Zo12220’, that is characterized by its free flowering habit as a nursery plant, its terminal and axillary flowers on the new shoots and old wood, its flowers in both spring and summer, and its flowers with tepals that are a blend of different shades of pink surrounding dark red stamens.

Description

Botanical classification: Clematis hybrid.

Variety denomination: ‘Zo12220’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis of hybrid origin and will be referred to hereafter by its cultivar name ‘Zo12220’. Clematis ‘Zo12220’ is a woody vine grown for use as a landscape plant.

Clematis ‘Zo12220’ was derived from an ongoing breeding program by the Inventor at his nursery in Boskoop, The Netherlands. The goal of the selection was to select a new cultivar of Clematis that as a nursery plant was free flowering in spring and summer with terminal and axillary flowers on new shoots using a cane size suitable for nursery production. ‘Zo12220’ was selected in 2012 and arose from a controlled cross made in 2007 between unnamed and unpatented plants from his breeding program; the female parent designated as No. 20030161 and the male parent designated as No. 19960354.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings under the direction of the Inventor in Boskoop, The Netherlands in 2012. Asexual propagation by softwood stem cutting 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 Clematis ‘Zo12220’ as a unique cultivar of Clematis.

1. ‘Zo12220’ exhibits a free flowering habit as a nursery plant.

2. ‘Zo12220’ exhibits terminal and axillary flowers on the new shoots and old wood.

3. ‘Zo12220’ exhibits flowers in both spring and summer.

4. ‘Zo12220’ exhibits flowers with tepals that are a blend of different shades of pink surrounding dark red stamens.

The female parent of ‘Zo12220’ differs from ‘Zo12220’ in having semi-double flowers in spring, tepals that are violet in color with a much smaller white base, and stamen connectives that are yellow in color. The male parent of ‘Zo12220’ differs ‘Zo12220’ in having flowers with tepals that are purple-violet in color, stamen connectives that are straight, and in lacking axillary flowers in spring. ‘Zo12220’ can be most closely compared to the Clematis cultivars ‘Hagley Hybrid’ (not patented) and ‘Pink Fantasy’ (not patented). Both are similar to ‘Zo12220’ in having pink flowers and in producing axillary flowers on shoots. ‘Hagley Hybrid’ differs from ‘Zo12220’ in having tepals that are violet in color at the base and have margins that are crinkled and are similar in color to the rest of the tepal, and in having stamen filaments that are pale purple in color. ‘Pink Fantasy’ differs from ‘Zo12220’ in having tepal margins that are crinkled and are a similar in color to the rest of the tepal, and in having stamen filaments that are white in color.

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 as grown outdoors in a 2-Liter rose container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a view of ‘Zo12220’ in bloom in spring.

The photograph in FIG. 2 provides a view of the flowers of ‘Zo12220’ in summer.

The photograph in FIG. 3 provides a close-up view of a cross section of a flower of ‘Zo12220’.

The colors of the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Clematis.
