The first public disclosure of the claimed plant, in the form of a sale, was made by Walters Gardens, Inc. on Apr. 1, 2019. Prior to that, on Dec. 1, 2018 the claimed plant was displayed as a photograph with a brief description on a website operated by Walters Gardens, Inc., followed by listing with a photograph and brief description in the Walters Gardens 19-20 Catalog circulated on May 29, 2019. Walters Gardens, Inc. obtained the plant and all information relating thereto, from the inventor. No plants of Achillea ‘Firefly Peach Sky’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.BACKGROUND OF THE PLANT
The present invention relates to the new and distinct yarrow herein also referred to as Achillea ‘Firefly Peach Sky’, by the cultivar name, ‘Firefly Peach Sky’, or as the new plant. The new plant was selected by the inventor as a single seedling resulting from a self-pollination of a proprietary, unreleased, unnamed seedling known only by the breeder code 13-5-8 (not patented) in research facility of a wholesale perennial grower based in Zeeland, Mich., USA. The cross was performed on Jun. 23, 2014 and seeds from this cross were collected on Sep. 23, 2014. The single seedling was then isolated and compared in subsequent years to other Yarrow and subsequently found to be different from all cultivars known to the discoverer and eventually given the breeder code 14-23-2.
Asexual propagation at the same nursery in Zeeland, Mich., USA by shoot tip cuttings and division since August of 2016 has shown ‘Firefly Peach Sky’ to be stable and reproduce true to type in successive generations.SUMMARY OF THE PLANT
Achillea ‘Firefly Peach Sky’ has not been observed in all possible environmental conditions. The phenotype may vary slightly with changes in environments such as light intensity, fertility, water availability, etc. without, however any variation in genotype.
Achillea ‘Firefly Peach Sky’ is distinct from all cultivars known to the inventor in the following traits:
- 1. Mounded upright habit about 90 cm tall and 100 cm wide;
- 2. Gray-green finely dissected foliage;
- 3. Heavily-branched compound corymbs with broad clusters of inflorescences;
- 4. Light peachy-orange ray florets that mature to yellow;
- 5. Sturdy stems withstand wind and rain;
- 6. Long flowering period beginning late June and continuing for about five weeks;
- 7. Repeat flowering if deadheaded.
Plants of Achillea ‘Firefly Peach Sky’ are most similar to ‘Pineapple Mango’ U.S. Plant Pat. No. 22,302 and ‘Peachy Seduction’ U.S. Plant Pat. No. 22,262. ‘Pineapple Mango’ is smaller in habit, both shorter and narrower than the new plant and the ray florets display different coloration. ‘Peachy Seduction’ is smaller and less upright in habit, the inflorescences and ray florets are on smaller stems with ray florets of a different color. Photographs or plants of the parent selection were not maintained, so no comparison with the parents are possible.
The color drawings illustrate the overall characteristics of Achillea ‘Firefly Peach Sky’ as a two-year-old plant in a full-sun trial garden in Zeeland, Mich. The colors are as true as reasonably possible given the technology available. The color values may vary slightly depending on light intensity and quality.
The following description of the new plant is based on a three-year-old plant growing in a full-sun trial garden in Zeeland, Mich., USA. Environmental conditions for the growing season daytime temperatures range between 12-30° C., and night temperatures range between 6-19° C. Except for ordinary dictionary color usage, color references are according to The Royal Horticultural Society Colour Chart, 2015 edition.
