USPP25703P2 - Deutzia plant named ‘Mincream’ - Google Patents

Abstract

A new and distinct cultivar of Deutzia plant named ‘Mincream’, characterized by its compact, low spreading to trailing plant habit; variegated leaves that are green and pale yellow in color; freely flowering habit; white-colored flowers; and good garden performance.

Description

Botanical designation: Deutzia gracilis.

Cultivar denomination: ‘MINCREAM’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Deutzia plant, botanically known as Deutzia gracilis and hereinafter referred to by the name ‘Mincream’.

The new Deutzia plant is a naturally-occurring branch mutation of an unnamed proprietary selection of Deutzia gracilis, not patented. The new Deutzia plant was discovered and selected by the Inventor on a single plant of the proprietary selection in a controlled outdoor nursery environment in La Ménitré, Maine et Loire, France in July, 2002.

Asexual reproduction of the new Deutzia plant by cuttings in a controlled greenhouse environment in La Ménitré, Maine et Loire, France since August, 2002 has shown that the unique features of this new Deutzia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Deutzia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Mincream’. These characteristics in combination distinguish ‘Mincream’ as a new and distinct Deutzia plant:

• • 1. Compact, low spreading to trailing plant habit.
  • 2. Variegated leaves that are green and pale yellow in color.
  • 3. Freely flowering habit.
  • 4. White-colored flowers.
  • 5. Good garden performance.

Plants of the new Deutzia differ primarily from plants of the unnamed proprietary parent selection in leaf color as plants of the unnamed proprietary parent selection have non-variegated leaves.

Plants of the new Deutzia can also be compared to plants of Deutzia longifolia ‘Aurea’, not patented. In side-by-side comparisons conducted in La Ménitré, Maine et Loire, France, plants of the new Deutzia and ‘Aurea’ differed primarily in the following characteristics:

• • 1. Plants of the new Deutzia were more compact than plants of ‘Aurea’.
  • 2. Plants of the new Deutzia were low spreading to trailing whereas plants of ‘Aurea’ were upright.
  • 3. Plants of the new Deutzia and ‘Aurea’ differed in leaf color as plants of ‘Aurea’ had green and darker yellow variegated leaves.
  • 4. Leaves of plants of the new Deutzia did not sunburn under full sunlight conditions whereas leaves of plants of ‘Aurea’ sunburned under full sunlight conditions.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Deutzia 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 Deutzia.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Mincream’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Mincream’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in one-gallon containers during the summer in an outdoor nursery in Grand Haven, Mich. and under commercial production practices. Plants were two years old when the photographs and description were taken.
