USPP31155P2 - Eucomis plant named ‘African Night’ - Google Patents

Abstract

A new and distinct Eucomis plant named ‘African Night’ with rounded-mound habit of glossy, finely serrulate, strap-like, arching leaves emerging rich burgundy colored and developing to olive green. Beginning in mid-summer and lasting for about four weeks, the plants produce tall racemes with dense flowers of rosy pink. ‘African Night’ is winter-hardy to USDA zone 6 and useful as a specimen landscape plant, en masse, as a container plant or as a cut flower.

Description

Latin name and variety denomination of the plant:

Botanical classification: Eucomis comosa (Houtt.) Wehrh.

Variety denomination: ‘African Night’.

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

The first public disclosure of the claimed plant was made by Walters Gardens, Inc. on Feb. 1, 2018 when the claimed plant was displayed as a photograph with short description on a website owned and operated by Walters Gardens, Inc., and the initial sale of the new plants was on Jul. 16, 2018, also by Walters Gardens, Inc. who obtained the plant and all information relating thereto, from the inventor. No plants of Eucomis ‘African Night’ 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 disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND AND ORIGIN OF THE PLANT

There are twelve recognized species within the genus Eucomis in the Asparagaceae family. The present invention relates to a new and distinct hosta plant, Eucomis ‘Africa Night’ hereinafter also referred to as the new plant or the cultivar name, ‘Africa Night’. Eucomis ‘Africa Night’ was hybridized at a wholesale nursery in Zeeland, Mich., USA in Jul. 16, 2009 as a cross between Eucomis comosa ‘Reuben’ (not patented) as the female or seed parent, and Eucomis comosa ‘Sparkling Burgundy’ (not patented) as the male or pollen parent. The new plant is a single seedling selection among several in that cross identified by the breeder code 9-6-01 through the trial process. The new plant has been asexually propagated by leaf accessions and separation of the bulbs at the same nursery in Zeeland, Mich., USA since 2014, with the resultant asexually propagated plants having retained all the same traits as the original plant.

BRIEF SUMMARY OF THE PLANT

Eucomis ‘African Night’ is a distinct and new variety of Pineapple Lily. The new plant can be compared with the parent cultivars, ‘EUW061’ U.S. Plant Pat. No. 23,699 and ‘Safari Adventure’ U.S. Plant patent application Ser. No. 16/350,797. ‘EUW061’ are comparable to the new variety but produce flowers that change in color intensity through maturity, and the foliage does not get the rich burgundy as the new plant is emerging. ‘Sparkling Burgundy’ is slightly more upright in foliage and the flowers open ivory white and change to a rosy pink with maturity. ‘Reuben’ is shorter in flower stem, and the flowers are smaller with more cranberry coloration and the leaves are more green and do not emerge with the rich burgundy coloration. ‘Safari Adventure’ has foliage with less burgundy coloration and the flowers change color with maturity.

Eucomis ‘African Night’ is distinct from all cultivars known to the inventor in the following combined traits:

• • 1. Bulbous winter-hardy perennial with strap-shaped arching leaves emerging from the ground;
  • 2. Foliage color begins emerging in the spring with deep burgundy coloring;
  • 3. Leaves are glossy above and below, the margins are finely serrulate and flat to boat-shaped;
  • 4. Each mature bulb produces a tall raceme with dense flowers that open rosy pink;
  • 5. Winter-hardy to USDA zone 6.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the new plant, including the unique traits grown in full-sun trial gardens in Zeeland, Mich. 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.
