USPP36001P2 - Agastache plant named ‘Guava Lava’ - Google Patents

Abstract

A new and unique cultivar of hyssop, Agastache plant named ‘Guava Lava’ with medium-sized, dense, rounded, well-branched habit. The flowers cover the top two-thirds of the plant, are large, coral-orangish-colored, with mauve-pink calyxes in densely branched panicles over an extended period beginning in early summer. The new plant is useful in the landscape and as a cut flower.

Description

Botanical denomination: Agastache hybrid.

Variety designation: ‘Guava Lava’.

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 Feb. 1, 2023, in the form of a website brief description and photograph followed by a short description. Walters Gardens, Inc. obtained the new plant and information about the new plant directly from the inventor. The first offer for sale of the new plant was on Feb. 6, 2023. No plants of Agastache ‘Guava Lava’ have been sold or offered for sale 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 Anise Hyssop plant or Hummingbird Mint from the genus Agastache and given the cultivar name ‘Guava Lava’. The new plant was the result of a single seedling selection from a cross on Jun. 8, 2017, by the inventor between the proprietary, unreleased, hybrid, 16-3-1 (not patented) as the female or seed parent and the proprietary, unreleased, proprietary hybrid 16-4-1 (not patented) as the male or pollen parent. The seeds from the pollination were collected in the late summer of 2017. The individually selected seedling was eventually given the breeder code 17-9-1 after being first isolated from trials at a nursery in Zeeland, MI during the summer of 2019. It was selected for the final introduction in the summer of 2020.

Agastache ‘Guava Lava’ has been asexually propagated at the same nursery in Zeeland, MI originally by basal shoot cuttings in 2018, followed by 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 ‘Guava Lava’, 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 seed parent has a taller habit, darker reddish flowers, and the flowers were smaller. The male parent has a lighter colored flower.

The nearest comparison varieties known to the inventor are: ‘Peachie Keen’ U.S. Plant Pat. No. 25,886, ‘Mango Tango’ U.S. Plant Pat. No. 28,747, ‘Kudos Coral’ U.S. Plant Pat. No. 25,613, ‘Kudos Mandarin’ U.S. Plant Pat. No. 25,381, ‘Apricot Sprite’ (not patented), and ‘Summer Sunset’ U.S. Plant Pat. No. 23,623.

‘Peachie Keen’ has a similar habit in both height and width but with apricot-peach-colored flowers and purplish-pink calyxes. ‘Mango Tango’ has a shorter and more compact habit and the flowers are light peach to mango-orange colored. ‘Kudos Mandarin’ has deeper orange-colored flowers with a significantly smaller habit. ‘Kudos Coral’ has a narrower and smaller habit in both height and width, and the flower color is more reddish-colored. ‘Apricot Sprite’ has a slightly smaller habit with flowers of bright orange. ‘Summer Sunset’ is less winter-hardy, has a smaller and narrower habit, and the flower color are more orangish colored. Both ‘Kudos Mandarin’ and ‘Kudos Coral’ have not overwintered under similar conditions where the new plant has survived the winter.

Agastache ‘Guava Lava’ is distinct from the parents and all other anise hyssop known to the inventor in the following combined traits:

• • 1. Medium-sized, dense, well-branched, rounded, full, habit;
  • 2. Large flowers of coral-orangish coloration in densely branched panicles;
  • 3. Long bloom time with effectiveness extended by persistent, mauve-pink-colored calyxes;
  • 4. Foliage is medium green;
  • 5. Flowers covering the upper two-thirds of the plant beginning in early summer and continuing to fall.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant, including the 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 variations in color.
