USPP34910P2 - Agastache plant named ‘Royal Raspberry’ - Google Patents

Abstract

A new and unique cultivar of hyssop, Agastache plant named ‘Royal Raspberry’ with medium-sized, dense, mounded, well-branched habit and spring foliage color with burgundy cast. The large flowers of rosy-purple coloration begin in early summer and cover the top two-thirds of the plant. The effective flowering season is extended with burgundy-colored calyxes in densely branched panicles. The new plant is useful in the landscape and as a cut flower.

Description

Botanical denomination: Agastache hybrid.

Variety designation: ‘Royal Raspberry’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling disclosure of the claimed plant was made by Walters Gardens, Inc. on Dec. 1, 2021, in the form of a website brief description and photograph followed by a short description. The first enabling disclosure of a sale of the claimed plant was on May 17, 2021, by Walters Gardens, Inc to Casertano Greenhouses and Farms, Inc. Walters Gardens, Inc. obtained the new plant and information about the new plant directly from the inventor. No plants of Agastache ‘Royal Raspberry’ 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 to 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 INVENTION

The present invention relates to a new and distinct hyssop plant or anise hyssop from the genus Agastache and given the cultivar name ‘Royal Raspberry’. The new plant was the result of a single seedling selection from a self-pollination on Jul. 15, 2015, by the inventor of the proprietary, unreleased, hybrid, clone Agastache 14-8-1 (not patented). The seeds from the self-pollination were collected in late summer of 2015. The individually selected seedling was eventually given the breeder code 15-12-38 after being first isolated from trials at a nursery in Zeeland, Mich. during the summer of 2017. It was selected for the final introduction in the summer of 2019.

Agastache ‘Royal Raspberry’ has been asexually propagated at the same nursery in Zeeland, Mich. using traditional shoot tip and stem cutting procedures and found to reproduce plants that are identical and exhibit all the characteristics of the original plant in successive generations of asexual propagation.

The new plant, Agastache ‘Royal Raspberry’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype.

In comparison to the new plant, the parent is shorter and more mounded in habit and the flower color is a lighter lavender-pink.

The nearest comparison varieties known to the inventor are: ‘Mango Tango’ U.S. Plant Pat. No. 25,747, ‘Rosie Posie’ U.S. Plant Pat. No. 25,857, ‘Kudos Ambrosia’ U.S. Plant Pat. No. 25,616, ‘Kudos Mandarin’ U.S. Plant Pat. No. 25,381, ‘Summer Sunset’ U.S. Plant Pat. No. 23,623, ‘Ava’ (not patented), ‘Desert Solstice’ (not patented), ‘Desert Sunrise’ (not patented) and ‘Bolero’ (not patented).

‘Mango Tango’ has a significantly smaller habit in both height and width and has flowers that are light-peach to dusky-orange. ‘Rosie Posie’ has a shorter and more compact habit, and the flowers are hot-pink colored. ‘Kudos Ambrosia’ has lighter-pink flowers from orangish-peach buds and the calyxes are not as dark. ‘Kudos Mandarin’ has deeper-orange-colored flowers with a significantly smaller habit ‘Ava’ has a height of 120 to 150 cm with a narrow upright habit and flowers that are deep rose-pink. ‘Summer Sunset’ is less winter-hardy, smaller and narrower in habit, and the flower color contains more orangish coloration. ‘Desert Solstice’ has a similar height, but more upright narrow habit and flowers that are rosy-pink and calyxes that are a rosy fuchsia. ‘Desert Sunrise’ has a habit that is about 120 cm tall while upright and 60 cm wide with flowers that are a lighter orangish-pink. ‘Bolero’ has is more mounded in habit and more compact, hut has similar spring foliage color.

The new plant Agastache ‘Royal Raspberry’ is distinct from the parent and all other anise hyssop known to the inventor in the following combined traits:

• • 1. Medium sized, dense, mounded, well-branched habit;
  • 2. Large flowers of rosy-purple coloration in densely branched panicles;
  • 3. Long bloom time with effectiveness extended by persistent, burgundy-colored calyxes;
  • 4. Flowers covering the upper two-thirds of the plant for about five weeks beginning in early summer;
  • 5. Foliage displays a burgundy cast in the spring.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant, including its unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.
