plant named ‘Cherry Chocolate Chip’

Abstract

A new and unique Manfreda plant named ‘Cherry Chocolate Chip’ characterized by flattened mound plant habit and variegated leaves having white margins and chartreuse centers with irregular greyed-purple spotting in the center and cherry red spotting on the margin. ‘Cherry Chocolate Chip’ readily produces tall, upright flower spikes of chocolate-mahogany-colored flowers. The new plant is suitable for the landscape garden or potted for indoor, garden or patio beautification.

Description

Botanical classification: Manfreda undulata (Klotzsch) Rose.

Variety denomination: ‘Cherry Chocolate Chip’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct Manfreda plant, Manfreda ‘Cherry Chocolate Chip’ 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 Manfreda ‘Chocolate Chip’ (not patented) on Aug. 10, 2012. The new plant has been successfully asexually propagated initially by division at the same nursery in Zeeland, Mich. and also by 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.

BRIEF SUMMARY OF THE INVENTION

Manfreda ‘Chocolate Cherry Chip’ differs from its parent, ‘Chocolate Chip’, as well as all other Manfreda cultivars known to the applicant. The most similar known variety is Manfreda ‘Mint Chocolate Chip’ (U.S. Plant Pat. No. 29,343). ‘Mint Chocolate Chip’ develops silvery-blue-green foliage with greyed-purple spotting compared to the white margined leaves with cherry-red spotting with chartreuse centers with greyed-purple spotting. The foliage of ‘Mint Chocolate Chip’ are thicker top to bottom than the new plant. The foliage of ‘Cherry Chocolate Chip’ is also narrower than ‘Mint Chocolate Chip’. Compared with ‘Chocolate Chip’, the new plant has foliage with white margins that shows the greyed-purple spotting as a brighter cherry-red without the chartreuse chlorophyll in the margin.

Manfreda ‘Cherry Chocolate Chip’ differs from all other Manfreda known to the applicant, by the combination of the following traits:

• • 1. Long, horizontal to arching, chartreuse, sinuate foliage with white margins;
  • 2. Leaves develop irregular greyed-purple spotting that exhibits a cherry-red in regions of the white margin;
  • 3. Moderate to rapid growth rate with good natural pup production;
  • 4. Chocolate-mahogany flowers with long filaments and style on tall, stiff, vertical scapes.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs 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. The new plant, Manfreda ‘Cherry Chocolate Chip’, 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 two-year old plant in a commercial wholesale greenhouse in Zeeland, Mich. with supplemental water and fertilizer as needed.
