Abstract

A new and distinct cultivar of Tricyrtis plant named ‘Taipei Silk’, characterized by its upright and outwardly spreading plant habit; freely branching growth habit; glossy dark green-colored foliage; large inflorescences with numerous purple and white-colored flowers; and winter hardy to USDA Zone 6.

Description

Botanical designation: Tricyrtis hybrida.
Cultivar denomination: ‘Taipei Silk’.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Tricyrtis plant, botanically known as Tricyrtis hybrida, and hereinafter referred to by the name ‘Taipei Silk’.
The new Tricyrtis is a product of a planned breeding program conducted by the Inventor in Hubbardston, Mass. The objective of the breeding program was to develop new long-flowering and winter-hardy Tricyrtis cultivars with strong foliage and large inflorescences with attractive flowers.
The new Tricyrtis originated from a cross-pollination made by the Inventor in 1992 in Hubbardston, Mass. of an unnamed selection of Tricyrtis formosana, not patented, as the female, or seed, parent with an unnamed selection of Tricyrtis lasiocarpa, not patented, as the male, or pollen, parent. The new Tricyrtis was discovered and selected by the Inventor in 1993 as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Hubbardston, Mass.
Asexual reproduction of the new cultivar by cuttings in a controlled environment in Hubbardston, Mass. since 1994 has shown that the unique features of this new Tricyrtis are stable and reproduced true to type in successive generations of asexual propagation.
SUMMARY OF THE INVENTION
Plants of the cultivar Taipei Silk have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Taipei Silk’. These characteristics in combination distinguish ‘Taipei Silk’ as a new and distinct cultivar:
    • 1. Upright and outwardly spreading plant habit.
    • 2. Freely branching growth habit.
    • 3. Glossy dark green-colored foliage.
    • 4. Large inflorescences with numerous purple and white-colored flowers.
    • 5. Winter hardy to USDA Zone 6.
Plants of the new Tricyrtis differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Tricyrtis have larger inflorescences and are more freely flowering than plants of the female parent selection.
    • 2. Leaves of plants of the new Tricyrtis are glossy whereas leaves of plants of the female parent selection are dull and pubescent.
    • 3. Plants of the new Tricyrtis and the female parent selection differ in flower color as plants of the female parent selection have pale lavender-colored flowers.
Plants of the new Tricyrtis differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Tricyrtis have terminal and axillary inflorescences whereas plants of the male parent selection only have a single terminal panicle.
    • 2. Leaves of plants of the new Tricyrtis are glossy whereas leaves of plants of the male parent selection are dull.
    • 3. Plants of the new Tricyrtis are more winter hardy than plants of the male parent selection.
Plants of the new Tricyrtis can be compared to plants of the Tricyrtis cultivar Gilty Pleasure, disclosed in U.S. Plant Pat. No. 13,688. Plants of the new Tricyrtis differ from plants of the cultivar Gilty Pleasure primarily in leaf coloration as plants of the cultivar Gilty Pleasure have golden yellow-colored leaves.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Tricyrtis, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Tricyrtis.
The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Taipei Silk’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of typical flowers of ‘Taipei Silk’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations, measurements and values describe plants of the new Tricyrtis grown in Lancaster, Pa. in a polyethylene-covered greenhouse during the summer. During the production of the plants, day temperatures ranged from 21° C. to 46° C. and night temperatures ranged from 18° C. to 29° C. Plants used for the photographs and description were about one year old. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
