Abstract

Description

Botanical designation: Spiraea japonica.
Cultivar denomination: ‘YAN’.
CROSS-REFERENCED TO RELATED APPLICATIONS
Applicant: Timothy D. Wood
Title: Spiraea Plant Named ‘Galen’
Filed: U.S. Plant patent application Ser. No. 12/583,682.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Spiraea plant, botanically known as Spiraea japonica and hereinafter referred to by the name ‘Yan’.
The new Spiraea plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to develop new compact Spiraea cultivars with strong foliage, large flowers and resistance to Powdery Mildew.
The new Spiraea plant originated from an open-pollination during the summer of 2004 of Spiraea japonica ‘Walbuma’, disclosed in U.S. Plant Pat. No. 9,363, as the female, or seed, parent with an unknown selection of Spiraea japonica, as the male, or pollen, parent. The new Spiraea plant was discovered and selected by the Inventor during the summer of 2006 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.
Asexual reproduction of the new Spiraea plant by softwood cuttings in a controlled greenhouse environment in Grand Haven, Mich. since the summer of 2006 has shown that the unique features of this new Spiraea plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Spiraea have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Yan’. These characteristics in combination distinguish ‘Yan’ as a new and distinct cultivar of Spiraea:
    • 1. Compact, upright, outwardly spreading and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Leaves that are yellow green in color.
    • 5. Numerous pink-colored flowers.
    • 6. Good garden performance.
    • 7. Resistance to Powdery Mildew.
Plants of the new Spiraea can be compared to plants of the female parent, ‘Walbuma’. Plants of the new Spiraea differ from plants of ‘Walbuma’ in the following characteristics:
    • 1. Plants of the new Spiraea are more compact than plants of ‘Walbuma’.
    • 2. Plants of the new Spiraea are more freely branching than plants of ‘Walbuma’.
    • 3. Plants of the new Spiraea have larger leaves than plants of ‘Walbuma’.
    • 4. Plants of the new Spiraea and ‘Walbuma’ differ in leaf color as plants of ‘Walbuma’ have golden-colored leaves.
    • 5. Plants of the new Spiraea and ‘Walbuma’ differ slightly in flower color.
    • 6. Plants of the new Spiraea are more resistant to Powdery Mildew than plants of ‘Walbuma’.
Plants of the new Spiraea can be compared to plants of the Spiraea japonica ‘Galen’, disclosed in a U.S. Plant patent application filed concurrently with this application. Plants of the new Spiraea differ from plants of ‘Galen’ in the following characteristics:
    • 1. Plants of the new Spiraea are more compact than plants of ‘Galen’.
    • 2. Plants of the new Spiraea and ‘Galen’ differ in leaf color.
    • 3. Plants of the new Spiraea are not as freely flowering as plants of ‘Galen’.
    • 4. Plants of the new Spiraea and ‘Galen’ differ in flower color as plants of ‘Galen’ have purple-colored flowers.
Plants of the new Spiraea can also be compared to plants of the Spiraea japonica ‘Gold Mound’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Spiraea differed from plants of ‘Gold Mound’ in the following characteristics:
    • 1. Plants of the new Spiraea were shorter than plants of ‘Gold Mound’.
    • 2. Plants of the new Spiraea and ‘Gold Mound’ differed in flower color.
    • 3. Plants of the new Spiraea were more resistant to Powdery Mildew than plants of ‘Gold Mound’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Spiraea plant, 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 Spiraea plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Yan’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of typical inflorescences and leaves of ‘Yan’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants of the new Spiraea grown in three-gallon containers in Grand Haven, Mich. during the spring and early summer in a polyethylene-covered greenhouse and under conditions which closely approximate commercial production. Plants were three years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
