x plant named ‘Painted Desert’

Abstract

A new and unique x Mangave plant named ‘Painted Desert’ characterized by compact habit and lanceolate foliage with chartreuse green color with darker margins in lower ultraviolet light exposure and in high ultraviolet light exposure developing reddish mottling with glaucous covering speckling and blushing concentrated in the basal portions.

Description

Botanical classification: Agave times x Mangave hybrid.

Variety denomination: ‘Painted Desert’.

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

The first non-enabling disclosure of the claimed plant, in the form of a private sale, was made by Walters Gardens, Inc. on Jul. 23, 2018 to Plant Delights Nursery, Inc. Plants for this sale were obtained from the inventor. Since then, on Feb. 14, 2019, the plant was first advertised on a website managed by Walters Gardens, Inc. No plants of x Mangave ‘Painted Desert’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior 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 ‘Painted Desert’ that was hybridized by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as a cross between a proprietary unnamed selection of Agave nizandensis (not patented) as the female or seed parent times and x Mangave ‘Bloodspot’ (not patented) as the male or pollen parent. The cross was performed Jul. 10, 2014 and seeds were harvested and sown later the following autumn. Through trials at the same nursery the plant was referred to by the code 14-171-8. The new plant has been successfully asexually propagated by sterile shoot-tip tissue culture and by basal offsets at the same nursery in Zeeland, Mich. The asexual propagation by tissue culture and basal offsets has been found to produce stable and identical plants that maintain all the unique characteristics of the original plant.

BRIEF SUMMARY OF THE INVENTION

X Mangave ‘Painted Desert’ differs from its parents as well as all other Manfreda, Agave and x Mangave known to the applicant. The female parent has a flatter habit with fewer leaves per plant that are shorter and wider, has small marginal teeth, moderately channeled or concavo-convex with a lighter chartreuse along midrib, but the leaves do not have reddish spots or reddish pigmentation. The male parent is more upright in habit with greater number of leaves per plant, with foliage that is shorter, more glaucous, thicker (adaxial to abaxial), dark brown around the marginal teeth and larger terminal spines and fewer, less-overlapping, mahogany spots.

The most similar known X Mangave cultivar known to the inventor are: ‘Blazing Saddles’ U.S. Plant Pat. No. 31,274, ‘Mission to Mars’ U.S. Plant Pat. No. 29,393, ‘Red Wing’ U.S. Plant patent application Ser. No. 16/350,922, ‘Thunderbird’ U.S. Plant Pat. No. 31,248, ‘Racing Stripes’ U.S. Plant Pat. No. 31,251 and copending ‘Shadow Waltz’ U.S. Plant patent application Ser. No. 16/501,795.

‘Blazing Saddles’ has broader, more lustrous, less glaucous leaves with more reddish spotting in high light intensity. ‘Mission to Mars’ has much larger, broader foliage, larger marginal teeth, larger habit, less glaucous and the foliage is more solid red in high ultraviolet light. ‘Red Wing’ has more leaves per plant that are broader and the reddish coloration of cherry-red is more intense with more coverage of the leaf. ‘Thunderbird’ is more compact in habit, the leaves are shorter, thicker and more fibrous than the new plant. Both ‘Red Wing’ and ‘Thunderbird’ are predominantly reddish purple in foliage and lack the lighter chartreuse along the midrib. ‘Racing Stripes’ has wider leaves and more upright arching habit, more pronounced marginal teeth and the foliage has the lighter chartreuse along the midrib without any reddish purple spotting or mottling. ‘Shadow Waltz’ has more flexible marginal teeth and lacks the semi-flexible mucro at the leaf apex. ‘Shadow Waltz’ has the lighter chartreuse along the midrib and lacks the reddish purple spotting or mottling.

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

• • 1. Compact habit with about 60 leaves;
  • 2. Foliage lanceolate with small semi-flexible marginal teeth and semi-flexible sharp apex;
  • 3. Foliage has chartreuse center and darker green margin and with high ultraviolet light develops reddish speckling concentrated proximally on leaves with glaucous covering on top and bottom;
  • 4. Moderate growth rate;

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 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.

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.
