BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Achillea plant, botanically known as Achillea millefolium,and hereinafter referred to by the name ‘Pineapple Mango’.
The new Achillea plant is a naturally-occurring whole plant mutation of Achillea millefolium ‘Summer Pastels’, not patented. The new Achillea plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘Summer Pastels’ in July, 2005 in a controlled outdoor nursery environment in Stavenisse, The Netherlands. The selection of this plant was based on its unique inflorescence coloration.
Asexual reproduction of the new Achillea plant by vegetative cuttings in a controlled environment in Lancaster, Pa. since August, 2006, has shown that the unique features of this new Achillea plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Achillea have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Pineapple Mango’. These characteristics in combination distinguish ‘Pineapple Mango’ as a new and distinct cultivar of Achillea plant:
- 1. Upright, columnar and mounding plant habit.
- 2. Strong and vigorous growth habit.
- 3. Freely branching habit.
- 4. Freely flowering habit with plants remaining in flower for a long period time.
- 5. Inflorescences with pink-colored ray florets that become yellow with development.
- 6. Good garden performance.
Plants of the new Achillea differ from plants of the parent, ‘Summer Pastels’, in the following characteristics:
- 1. Plants of the new Achillea are more compact than and not as open as plants of ‘Summer Pastels’.
- 2. Plants of the new Achillea are more freely branching and have stronger stems than plants of ‘Summer Pastels’.
- 3. Plants of the new Achillea flower more uniformly than plants of ‘Summer Pastels’.
- 4. Ray floret color of plants of the new Achillea does not fade as quickly as ray floret color of plants of ‘Summer Pastels’.
Plants of the new Achillea differ primarily in ray floret coloration from plants of Achillea millefolium ‘Peachy Seduction’, disclosed in a U.S. Plant patent application Ser. No. 12/804,003 filed concurrently.
Plants of the new Achillea can also be compared to plants of Achillea millefolium ‘Appleblossom’, not patented. In side-by-side comparisons conducted in Lancaster, Pa., plants of the new Achillea differed from plants of ‘Appleblossom’ in the following characteristics:
- 1. Plants of the new Achillea were more freely branching than plants of ‘Appleblossom’.
- 2. Plants of the new Achillea had shorter internodes than plants of ‘Appleblossom’.
- 3. Ray floret color of plants of the new Achillea did not fade as quickly as ray floret color of plants of ‘Appleblossom’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Achillea plant. These photographs show 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 Achillea plant.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Pineapple Mango’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Pineapple Mango’.
DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following observations and measurements describe plants grown in one-gallon containers in a polyethylene-covered greenhouse in Lancaster, Pa. during the spring and under conditions and practices which approximate those generally used in commercial Achillea production. During the production of the plants, day temperatures ranged from 16° C. to 32° C. and night temperatures averaged 16° C. Plants were pinched one time. Measurements and numerical values represent averages for typical nine-month old flowering plants. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
