X Mangave plant named ‘Pineapple Express’

Abstract

A new and unique X Mangave plant named ‘Pineapple Express’ characterized by rapid growth rate and compact habit of stiff, upright to outward pointing, succulent foliage gray-green coloring and burgundy speckling. The green flowers on heavily-branched, tall, stiff, purplish tinted scapes are loaded with nectar are highly attractive to hummingbirds.

Description

Botanical classification: Manfreda×Agave hybrid.

Variety denomination: ‘Pineapple Express’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave plant, X Mangave ‘Pineapple Express’ hybridized by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as an individual select seedling from a cross between X Mangave ‘Jaguar’ (not patented) times X Mangave ‘Bloodspot’ (not patented). The cross was performed on Jul 12, 2011 and seeds harvested on Nov. 7, 2011. Through repeated trials beginning in 2012 at the same nursery and since the new plant was referred to by the breeder code XMAN11-18-05. 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 ‘Pineapple Express’ 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 ‘Pineapple Express’ differs from its parents as well as all other Manfreda, Agave and X Mangave known to the applicant. Compared to the female parent, X Mangave ‘Jaguar’, the new plant is smaller, more compact, and the foliage is shorter. Compared to the male parent, ‘Bloodspot’, the new plant is less compact, has less stiffer foliage with an abundance of greyed-purple speckling. The most similar known X Mangave cultivar is ‘King Cobra’ (co-pending U.S. Plant Patent Application). Compared to ‘King Cobra’, ‘Pineapple Express’ has foliage that is more upright, less broad, with larger burgundy speckling and less glossiness to the adaxial and abaxial leaf surfaces.

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

• • 1. Stiff, upright to outward pointing, succulent foliage with compact habit;
  • 2. Gray-green leaves with large speckling of burgundy spots;
  • 3. Moderate to rapid growth rate with good natural pup production;
  • 4. Flowers on stiff, tall, lightly-branched scapes with purplish tinting.

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.
