CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority from U.S. Provisional Patent Application No. 62/710,266, filed Feb. 14, 2018, which is incorporated herein by reference in its entirety.

Botanical classification: Manfreda x Agave hybrid.

Variety denomination: ‘Carnival’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave plant ‘Carnival’ discovered by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as an uninduced whole-plant mutation from a proprietary selection from plants originating in a tissue cultured batch of X Mangave ‘Jaguar’ (not patented) in September of 2015. Through trials at the same nursery since that discovery the plant was referred to by the code 13-SP-Mang-285-4. The new plant has been successfully asexually propagated initially by division at the same nursery in Zeeland, Mich. and also by tissue culture. Both methods of asexual propagation systems have been found to produce stable and identical plants that maintain all the unique characteristics of the original plant.

No plants of X Mangave ‘Carnival’ have been sold, in this country or anywhere in the world, prior to the priority date of this application, nor has any disclosure of the new plant been made before the priority date of this application except that which was disclosed within one year of the priority date of this application, and was either derived directly or indirectly from the inventor.

BRIEF SUMMARY OF THE INVENTION

X Mangave ‘Carnival’ differs from its parent, ‘Jaguar’, as well as all other Manfreda, Agave and X Mangave known to the applicant. The most similar known X Mangave cultivar is ‘Kaleidoscope’ U.S. Plant Pat. No. 28,614. ‘Kaleidoscope’ is a similar X Mangave sport from the same parent, but the variegation pattern is reversed with the lighter coloration in the margin and the dark green in the center. ‘Jaguar’ has the habit and shape of the new plant, but the foliage coloration is dark green with burgundy spotting. Other similar X Mangave with chimera variegation include: ‘Cappuccino’ (not patented) with a creamy white center and mahogany-green margin. There are numerous variegated Agave known to the inventor including Agave ‘Dessert Diamond’ U.S. Plant Pat. No. 26,384 with a very compact habit and rigid spiny leaves and bright cream margin and medium green leaf centers.

The new plant is unique from all of these variegated Agave, X Mangave and Manfreda known to the inventor by the following combined traits:

    • 1. Long, arching, succulent foliage with blue-green margins and variegated yellowish-green to yellowish cream centers;
    • 2. Foliage develops greyed-purple to cherry-red speckling throughout and strong cherry-red tinting in the center;
    • 3. Moderate growth rate with good natural pup production;

BRIEF DESCRIPTION OF THE DRAWINGS

The photograph of the new plant demonstrates the overall appearance of the new plant including the unique traits as a three-year-old plant grown in a container in a greenhouse 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.

FIG. 1 shows a close-up of the foliage from above.

FIG. 2 shows the new plant in a container from the side.

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 ‘Carnival’, 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.
