USPP29917P2 - X Mangave plant named ‘Spotty Dotty’ - Google Patents

Abstract

A new and unique X Mangave plant named ‘Spotty Dotty’ characterized by long, broad, straight, foliage, that develop small reddish-purple spots densely covering the upper and lower surfaces. Leaves have small and medium sized semi-flexible marginal spines and semi-flexible apical spine. Growth rate is rapid to moderate. The new plant is suitable for the garden or as a potted plant in the garden or home.

Description

Botanical classification: hybrid; x Mangave times Agave.

Variety denomination: ‘Spotty Dotty’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave hybrid plant, X Mangave ‘Spotty Dotty’ hybridized by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as cross between a proprietary unreleased hybrid known only by the breeder code X Mangave H10-2 (not patented) as the female or seed parent times a selection of Agave bovicornuta (not patented) as the male or pollen parent. The cross was performed on Apr. 17, 2012 and seeds were harvested and sown on Aug. 1, 2012. After trials at the same nursery the plant was assigned the breeder code XMANG-12-18-7. The new plant has been successfully asexually propagated initially by division at the same nursery in Zeeland, Mich. and also by sterile shoot-tip 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 ‘Spotty Dotty’ have been sold, under this or any name, in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which was disclosed or sold 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 ‘Spotty Dotty’ differs from its parents as well as all other Manfreda, Agave and X Mangave known to the applicant. The most similar known cultivars are X Mangave ‘Moonglow’ U.S. Plant Pat. No. 29,195, X Mangave ‘Inkblot’ U.S. Plant Pat. No. 29,431 and X Mangave ‘Pineapple Express’ U.S. Plant Pat. No. 28,613. In comparison, the female parent the leaves that are wider and has a lighter shade of green and the habit is flatter and less arching. Compared with the male parent the new plant has longer, narrower, more fleshy and more flexible foliage, with smaller and more flexible marginal spines, and heavy coverage of small reddish-purple coloration. ‘Moonglow’ differs from the new plant in having shorter, narrower, less arching foliage with more glaucous, silvery blue-green color and larger greyed-purple spotting. Compared with ‘Inkblot’ the new plant has broader leaves with smaller dots of reddish purple. Compared to ‘Pineapple Express’ U.S. Plant Pat. No. 28,613 the new plant has longer and broader leaves that have smaller and more consistently-sized reddish-purple coloration.

The new plant, ‘Spotty Dotty’, 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. Long, broad, straight, slightly-wavy, foliage;
  • 2. Leaves develop small dots of reddish-purple spots densely covering throughout upper and lower surfaces;
  • 3. Both medium and small-sized, semi-flexible teeth on leaf margins and semi-flexible apical spine;
  • 4. Moderate to rapid growth rate.

BRIEF DESCRIPTION OF THE DRAWING

The photographs of x Mangave ‘Spotty Dotty’; 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 the new plant having been grown in a container.

FIG. 2 shows a close-up of the foliage with dense spots and marginal leave spines of a plant grown outside for the third year.

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 ‘Spotty Dotty’, 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 grown for the last year in the ground in Zeeland, Mich. with supplemental water and fertilizer as needed.
