plant named ‘Shy’

Abstract

A new and distinct cultivar of Pieris plant named ‘Shy’, characterized by its compact plant habit; freely branching habit; leaves that are initially purple red in color and with development become green in color; inflorescences that are initially upright; relatively late flowering response; numerous deep purplish pink-colored flowers; and good garden performance.

Description

Botanical designation: Pieris japonica.

Cultivar denomination: ‘SHY’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Pieris plant, botanically known as Pieris japonica, and hereinafter referred to by the name ‘Shy’.

The new Pieris plant is a product of a planned breeding program conducted by the Inventor in Hopewell, Oreg. The objective of the breeding program is to develop new compact Pieris plants with upright inflorescences, stable and attractive flower color and good garden performance.

The new Pieris plant originated from a cross-pollination made by the Inventor in February, 1988, in Hopewell, Oreg., of Pieris japonica var. japonica ‘Reversal’, not patented, as the female, or seed, parent with the Pieris japonica var. taiwanensis ‘Shears’, not patented, as the male, or pollen, parent. The new Pieris plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Hopewell, Oreg. in March, 2004.

Asexual reproduction of the new Pieris plant by cuttings propagated in a controlled environment in Hopewell, Oreg. since 2004 has shown that the unique features of this new Pieris plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Pieris have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, length of growing season and/or light intensity without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Shy’. These characteristics in combination distinguish ‘Shy’ as a new and distinct Pieris plant:

• • 1. Compact plant habit.
  • 2. Freely branching habit.
  • 3. Leaves that are initially purple red in color and with development become green in color.
  • 4. Inflorescences that are initially upright.
  • 5. Relatively late flowering response.
  • 6. Numerous deep purplish pink-colored flowers.
  • 7. Good garden performance.

Plants of the new Pieris differ from plants of the female parent, ‘Reversal’, primarily in the following characteristics:

• • 1. Plants of the new Pieris are more freely branching than plants of ‘Reversal’.
  • 2. Plants of the new Pieris retain leaves for a longer period of time than plants of ‘Reversal’.
  • 3. Developing leaves of plants of the new Pieris are purple red in color whereas developing leaves of plants of ‘Reversal’ are yellow green in color.
  • 4. Inflorescences of plants of the new Pieris are more upright than inflorescences of plants of ‘Reversal’.
  • 5. Plants of the new Pieris flower later than plants of ‘Reversal’.
  • 6. Plants of the new Pieris are more freely flowering than plants of ‘Reversal’.
  • 7. Flowers of plants of the new Pieris are deep purplish pink in color whereas flowers of plants of ‘Reversal’ are red purple in color.

Plants of the new Pieris differ from plants of the male parent, ‘Shears’, primarily in the following characteristics:

• • 1. Developing leaves of plants of the new Pieris are purple red in color whereas developing leaves of plants of ‘Shears’ are yellow green in color.
  • 2. Flowers of plants of the new Pieris are deep purplish pink in color whereas flowers of plants of ‘Shears’ are white in color.
  • 3. Sepals, peduncles and leaf petioles of plants of the new Pieris are dark red in color whereas sepals, peduncles and leaf petioles of plants of ‘Shears’ are yellow green in color.

Plants of the new Pieris can be compared to the plants of the Pieris japonica ‘Passion’, disclosed in U.S. Plant Pat. No. 19,319. In side-by-side comparisons conducted in Hopewell, Oreg., plants of the new Pieris differed from plants of ‘Passion’ in the following characteristics:

• • 1. Developing leaves of plants of the new Pieris were purple red in color whereas developing leaves of plants of ‘Passion’ were yellow green in color.
  • 2. Plants of the new Pieris flowered later and flowers lasted for a longer period of time than plants of ‘Passion’.
  • 3. Flowers of plants of the new Pieris were narrower but had longer petals than flowers of plants of ‘Passion’.
  • 4. Flowers of plants of the new Pieris were deep purplish pink in color whereas flowers of plants of ‘Passion’ were red purple in color.
  • 5. Sepals of plants of the new Pieris were dark red in color whereas sepals of plants of ‘Passion’ were light yellow green in color.
