USPP31312P3 - X Mangave plant named ‘Mayan Queen’ - Google Patents

Abstract

A new and unique X Mangave plant named ‘Mayan Queen’ characterized by silver-grey, slightly-arching, slightly-wavy, lanceolate foliage with distinctly small firm spines on deeply-scalloped margins. Leaves develop greyed purple markings with strong ultraviolet light with reddish purple base. Plants are useful for landscaping as specimens or en masse or as container plants in the landscape or in the home.

Description

Botanical classification: x Mangave times Agave gypsophila.

Variety denomination: ‘Mayan Queen’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave x Agave hybrid plant, X Mangave ‘Mayan Queen’ hybridized by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as cross between X Mangave ‘Bloodspot’ (not patented) as the female or seed parent times an unnamed selection of Agave gypsophila (not patented) as the male or pollen parent. The cross was performed on Dec. 26, 2011 and seeds were harvested and later sown Aug. 8, 2012. Through trials at the same nursery the plant was originally assigned the breeder code XMANG-12-03-27. The new plant has been successfully asexually propagated initially by sterile shoot-tip tissue culture at the same nursery in Zeeland, Mich. For those skilled in the art, tissue culture methods of asexual propagation systems for ‘Mayan Queen’ have been found to produce stable and identical plants that maintain all the unique characteristics of the original plant.

No plants of X Mangave ‘Mayan Queen’ have been sold, under this or any name, in this country or anywhere in the world, prior to the filing of this application, except to a perennial nursery in Raleigh, N.C. No disclosure of the new plant been made prior to the filing of this application with the exception of that which was disclosed within one year of the filing of this application, and was either derived directly or indirectly from the inventor.

BRIEF SUMMARY OF THE INVENTION

X Mangave ‘Mayan Queen’ differs from its parents as well as all other Manfreda, Agave and X Mangave known to the applicant. Compared with the female parent ‘Bloodspot’ the new plant has broader, longer and more upright leaves with more flexible apical spines and larger, more outright, mounded habit and the spots are more uniformly distributed and more greyed-purple compared with the burgundy spots of ‘Bloodspot’. Compared with the male parent, the new plant has flatter, narrower, shorter, more numerous, and less wavy foliage with more purple marking. The most similar cultivars known to the inventor are X Mangave ‘Purple People Eater’ U.S. Plant Pat. No. 29,949, X Mangave ‘Silver Fox’ U.S. Plant Pat. No. 29,642, X Mangave ‘Mission to Mars’ U.S. Plant Pat. No. 29,393 and X Mangave ‘Lavender Lady’ U.S. Plant Pat. No. 29,194. ‘Purple People Eater’ has shorter, less arching foliage with more intense purple marking, larger marginal and apical spines and has a more compact habit. ‘Silver Fox’ is more compact and has smaller foliage with more intense glaucous surfaces and less purple markings. ‘Mission to Mars’ has a larger habit with broader and longer foliage that is less glaucous and has intense reddish markings. ‘Lavender Lady’ is shorter and more compact in habit with more ovate foliage having more intense purplish markings.

The new plant, ‘Mayan Queen’, is unique from all of the above cultivars and all Agave, X Mangave and Manfreda known to the inventor by the following combined traits:

• • 1. Slightly-arching, slightly-wavy, lanceolate foliage with distinctly small firm spines on deeply-scalloped margins;
  • 2. Silver-grey foliage develops heavy glaucous covering and irregular greyed-purple spotting with strong ultraviolet light;
  • 3. Dense reddish purple leaf bases and slightly-flexible apical spines;
  • 4. Moderate growth rate.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of x Mangave ‘Mayan Queen’; demonstrate the overall appearance of the new plant including the unique traits of a four-year-old plant grown in a greenhouse in Zeeland, Mich. 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.

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 ‘Mayan Queen’, 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 four-year-old plant in a commercial wholesale greenhouse in Zeeland, Mich. with supplemental water and fertilizer as needed.
