X Mangave plant named ‘Kaleidoscope’

Abstract

A new and unique X Mangave plant named ‘Kaleidoscope’ characterized by long arching succulent foliage with blue-green centers and variegated yellowish-green to yellowish-cream margins developing under ultra violet light grey-purple to cherry red speckling throughout and strong cherry-red tinting in the margin. The green flowers on tall stiff scapes are loaded with nectar are highly attractive to hummingbirds.

Description

Botanical classification: Manfreda×Agave hybrid.

Variety denomination: ‘Kaleidoscope’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave plant, X Mangave ‘Kaleidoscope’ discovered by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as an uninduced whole-plant mutation in a tissue cultured crop of X Mangave ‘Jaguar’ (not patented) the Sep. 1, 2013. Through trials at the same nursery since that discovery the plant was referred to by the code 13-SP-Manf-285-9. 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 ‘Kaleidoscope’ have been sold, 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 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 ‘Kaleidoscope’ 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 ‘Expresso’ (not patented). ‘Expresso’ is a chimera sport of X Mangave ‘Macho Mocha’, which is a sport of Manfreda variegata×Agave celsii (not patented) presumably. ‘Jaguar’ is a chimera sport of Manfreda guttata and an unknown Agave. The variegation differs in that ‘Expresso’ is lighter cream to near white on the margin, whereas the variegation of ‘Kaleidoscope’ is a light lemon-green that develops more larger speckles and a cherry-red coloration on the margin and the leaves are narrower and not as thick adaxial to abaxial. Other similar X Mangave with chimera variegation include: ‘Cappuccino’ (not patented) with a lighter green center and blue-green margin; ‘Bloodspot’ PDN with edge (Avent) (not patented) has much shorter less arching foliage and the margin is nearly creamy white. There are numerous variegated Agave known to the inventor including Agave ‘Desert Diamond’ U.S. Plant Pat. No. 26,384 with a very compact habit and rigid spiny leaves and bright cream margin.

The new plant, ‘Kaleidoscope’, 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 centers and variegated yellowish-green to yellowish cream margins;
  • 2. Foliage develops greyed-purple to cherry-red speckling throughout and strong cherry-red tinting in the margin;
  • 3. Moderate to rapid growth rate with good natural pup production;
  • 4. Flowers on stiff, tall, lightly-branched scapes.

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 two-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.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
