USPP35382P2 - x Mangave plant named ‘Permanent Wave’ - Google Patents

Abstract

A new and unique X Mangave plant named ‘Permanent Wave’ is characterized by a compact mounded habit of ovate to deltoid-ovate leaves with dense, overlapping, intensely-glaucous, light-gray color. The new plant has large marginal teeth ending in a small, sharp, firm tooth and a large firm sharp apical mucro. The foliage frequently has depression images of the teeth left in the tops and bottoms of the leaves. The new plant has a moderate growth rate. The new plant is suitable as a potted houseplant plant, as a container plant for the patio or garden, and for the garden or planted in the landscape.

Description

Botanical classification: x Mangave times x Agave hybrid.

Variety denomination: ‘Permanent Wave’.

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

The first non-enabling public disclosure of x Mangave ‘Permanent Wave’ was on Feb. 1, 2022, with a brief description and photo on a website operated by Walters Gardens, Inc. This was followed by a brief description and photograph in the “Walters Gardens 2022-2023 Catalog” which was first distributed on Jun. 8, 2022. The first disclosure of the claimed plant, in the form of a sale, is planned to be made by Walters Gardens, Inc. on Feb. 15, 2022, to Plant Delights Nursery, Inc. All plants and information on ‘Permanent Wave’ have been provided to Walters Gardens, Inc. by the inventor. No plants of x Mangave ‘Permanent Wave’ 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 the new and distinct x Mangave plant, x Mangave ‘Permanent Wave’ hybridized on Nov. 23, 2015, by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as a cross between the proprietary unreleased hybrid known only by the breeder code x Mangave 12-11-1 (not patented) as the female or seed parent, and a proprietary selection of Agave ovatifolia (not patented) as the male or pollen parent. Through trials at the same nursery, the plant was referred to by the breeder code 16-56-2. The new plant has been successfully asexually propagated by shoot tip tissue culture in 2020 at the same nursery in Zeeland, Mich. These asexual propagation systems have been found to produce stable and identical plants that maintain all the unique characteristics of the original plant in successive generations.

BRIEF SUMMARY OF THE INVENTION

x Mangave ‘Permanent Wave’ differs from its parents as well as all other Manfreda, Agave, and x Mangave known to the applicant. The most similar known x Mangave cultivars known to the inventor are: ‘Lavender Lady’ U.S. Plant Pat. No. 29,194, ‘Whale Tale’ U.S. Plant Pat. No. 31,060, ‘Falling Waters’ U.S. Plant Pat. No. 30,650, ‘Silver Fox’ U.S. Plant Pat. No. 29,642, Agave ‘Frosty Blue’ (not patented), and Agave colorata.

The female parent has shorter, more wavy, and more glaucous foliage that is more folded along the midrib. The male parent, selection of Agave ovatifolia, is slower growing, and has a larger habit with flatter leaves.

‘Lavender Lady’ has shorter, more ovate, and flatter leaves that are more upright in habit, with smaller marginal teeth and a purplish cast. ‘Whale Tale’ has more leaves per plant, narrower, more arching, and more folded foliage, with smaller marginal teeth and faint burgundy spotting. ‘Falling Waters’ has longer, narrower, more arching foliage that has less glaucous covering with purple spotting. ‘Silver Fox’ is smaller in habit with leaves that are lanceolate with purple-lavender spots. Agave ‘Frosty Blue’ has shorter, broader, and flatter foliage that is more bluish than bluish-gray, the marginal teeth are larger and more burgundy-colored, and the growth rate is much slower.

The new plant, ‘Permanent Wave’, is unique from all Agave, X Mangave, and Manfreda known to the inventor by the following combined traits:

• • 1. Compact mounded habit;
  • 2. Leaves ovate to ovate-deltoid, dense, overlapping, intensely-glaucous, light bluish-gray;
  • 3. Foliage with large marginal teeth having a small sharp tooth and a large, firm, sharp, apical mucro;
  • 4. Moderate growth rate.

BRIEF DESCRIPTION OF THE DRAWING

The photograph of the new plant demonstrates the overall appearance of the new plant including the unique traits grown with supplemental water and fertilizer as needed. 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.

The FIGURE shows a side angle view of a three-year-old plant grown in a container.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, X Mangave ‘Permanent Wave’, 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. The following observations and size descriptions are of a three-year-old plant in a commercial wholesale greenhouse and in a full-sun trial garden in Zeeland, Mich. with supplemental water and fertilizer as needed.
