USPP26957P2 - Zizia plant named ‘Crazy Quilt’ - Google Patents

Abstract

A new cultivar of Zizia named ‘Crazy Quilt’, characterized by its heart shaped variegated foliage that changes color throughout the growing season, its spring foliage that emerges light green in color with an irregular white margin and a central dark green patch, its summer foliage that is gray-green in color with an irregular margin that is white and purple-pink in color, its fall and winter foliage that is two-toned purple and pink in color, and its small yellow umbellate flowers that emerge in the spring.

Description

Botanical classification: Zizia aptera.

Cultivar designation: ‘Crazy Quilt’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zizia aptera named ‘Crazy Quilt’ and is hereinafter referred to by its cultivar name ‘Crazy Quilt’.

The inventor discovered the new cultivar as a naturally occurring whole plant mutation in Framingham, Mass. in spring of 2002. ‘Crazy Quilt’ was discovered as a single unique plant in a tray of seedlings that had been planted with seeds collected from unnamed plants of Zizia aptera that were grown in a cultivated area.

Asexual propagation of the new cultivar was first accomplished by the Inventor by division in Framingham, Mass. in June 2004. Asexual propagation of the new cultivar by division and tissue culture has shown that the unique features are stable and 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 ‘Crazy Quilt’ as a new and unique cultivar of Zizia.

• • 1. ‘Crazy Quilt’ exhibits heart shaped variegated foliage that changes color throughout the growing season.
  • 2. ‘Crazy Quilt’ exhibits spring foliage that emerges light green in color with an irregular white margin and a central dark green patch.
  • 3. ‘Crazy Quilt’ exhibits summer foliage that is gray-green in color with an irregular margin that is white and purple-pink in color.
  • 4. ‘Crazy Quilt’ exhibits fall and winter foliage that is two-toned purple and pink in color.
  • 5. ‘Crazy Quilt’ exhibits small yellow umbellate flowers in the spring (similar to the species).

Plants of the parent species, Zizia aptera, differ from ‘Crazy Quilt’ in having non-variegated foliage. The flowers of ‘Crazy Quilt’ are not unique from the flowers of the species. There are no other cultivars of Zizia aptera known to the Inventor.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Zizia. The photographs were taken of a three year-old plant grown in a trail garden in Framingham, Mass.

The photograph in FIG. 1 provides a close-up view of the summer foliage of ‘Crazy Quilt’.

The photograph in FIG. 2 provides a view of the plant in bloom and the spring foliage of ‘Crazy Quilt’.

The photograph in FIG. 3 provides a view of the fall to winter foliage of ‘Crazy Quilt’.

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 Zizia.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of three year-old plants of the new cultivar as grown outdoors in a 2-gallon container in Framingham, Mass. 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.
