Botanical classification: x Mangave times Agave gypsophila.

Variety denomination: ‘Queen for a Day’.


The present invention relates to the new and distinct x Mangave x Agave hybrid plant, X Mangave ‘Queen for a Day’ was discovered by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA in a tissue cultured batch of x Mangave ‘Mayan Queen’ U.S. Plant Pat. No. 31,312 on Apr. 13, 2019. The new plant was a whole plant mutation forming a periclinal chimera. Through trials at the same nursery the plant was originally assigned the breeder code 19-SP-MANG-836-D. 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 ‘Queen for a Day’ have been found to produce stable and identical plants that maintain all the unique characteristics of the original plant in successive generations.

No plants of X Mangave ‘Queen for a Day’ have been sold, under this or any name, in this country or anywhere in the world, prior to the filing of this application. 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.


X Mangave ‘Queen for a Day’ differs from its parent mutation as well as all other Manfreda, Agave, and X Mangave known to the applicant. Compared with ‘Mayan Queen’ the new plant has foliage with a longitudinal olive-green center and solid, dark, purplish-grey margins. Other similar cultivars known to the inventor are x Mangave ‘Red Wing’ U.S. Plant Pat. No. 31,459, x Mangave ‘Silver Fox’ U.S. Plant Pat. No. 29,642, x Mangave ‘Purple People Eater’ U.S. Plant Pat. No. 29,949, x Mangave ‘Painted Desert’ U.S. Plant Pat. No. 31,630 x Mangave ‘Lavender Lady’ U.S. Plant Pat. No. 29,194 and x Mangave ‘Shadow Waltz’ U.S. Plant Pat. No. 31,601. ‘Red Wing’ has a more compact habit and the foliage is more reddish spotted without the longitudinal olive-green center. ‘Purple People Eater’ has shorter, less arching foliage with purple markings that are more spotted and less dense and without the longitudinal olive-green center, smaller marginal and apical spines and a more compact habit. ‘Silver Fox’ is more compact and has smaller foliage with more intense glaucous surfaces and purple spots without the longitudinal olive-green center. ‘Mission to Mars’ has a larger habit with broader and longer foliage that is less glaucous and has intense reddish markings and lacks the olive-green leaf center. ‘Painted Desert’ has narrower foliage with smaller marginal teeth and the purplish color is more spotted with reddish coloration in the center when grown in high intensity ultraviolet light and more chartreuse when grown in low intensity ultraviolet light. ‘Lavender Lady’ has shorter more ovate foliage having more uniform concentration of purplish spotting and without the longitudinal olive-green center and no marginal teeth on the foliage and the habit more upright with no arching of the foliage. ‘Shadow Waltz’ has narrower foliage with smaller marginal teeth and a chartreuse center with moderate green margins but no intense purple spotting or marking.

The new plant, ‘Queen for a Day’, 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 small, firm, apical spines and deeply-scalloped leaf margins;
    • 2. Dark, purplish-grey foliage margins with olive-green, longitudinal centers with heavy glaucous covering;
    • 3. Leaves have sharp, firm, apical spines and marginal teeth;
    • 4. Moderate growth rate.


The photographs of x Mangave ‘Queen for a Day’; demonstrate the overall appearance of the new plant including the unique traits of a fourteen-month-old plant grown in a full-sun outdoor trial garden 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.

The new plant, X Mangave ‘Queen for a Day’, 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.
