plant named ‘Minerva’

Abstract

A new and distinct cultivar of Neoregelia plant named ‘Minerva’, characterized by its broad and outwardly arching growth habit; relatively broad leaves that are outwardly arching and recurved in aspect; glossy leaves that are greyed yellow in color with distinct medium and dark green-colored longitudinal stripes, dark green-colored margins and purplish red-colored apices; upper (younger) leaves are mostly purplish deep red in color; flower development is not required for purplish red color development; and good interiorscape and landscape performance.

Description

Botanical designation: Neoregelia carolinae X (Neoregelia hybrida ‘Medium Rare’ X Neoregelia magdalenae).

Cultivar denomination: ‘MINERVA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Neoregelia plant, botanically known as Neoregelia carolinae X (Neoregelia hybrida ‘Medium Rare’ X Neoregelia magdalenae), and hereinafter referred to by the name ‘Minerva’.

The new Neoregelia plant is a product of a planned breeding program conducted by the Inventor in Princeton, Fla. The objective of the breeding program is to create new Neoregelia plants with uniquely colored leaves.

The new Neoregelia plant originated from a cross-pollination made by the Inventor in 2009 in Princeton, Fla. of an unnamed proprietary selection of Neoregelia carolinae, not patented, as the female, or seed, parent with an unnamed proprietary selection of Neoregelia hybrida ‘Medium Rare’ X Neoregelia magdalenae, not patented, as the male, or pollen, parent. The new Neoregelia plant was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Princeton, Fla. in 2010.

Asexual reproduction of the new Neoregelia plant by offsets in a controlled environment in Princeton, Fla. since 2010, has shown that the unique features of this new Neoregelia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Neoregelia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Minerva’. These characteristics in combination distinguish ‘Minerva’ as a new and distinct Neoregelia plant:

• • 1. Broad and outwardly arching growth habit.
  • 2. Relatively broad leaves that are outwardly arching and recurved in aspect.
  • 3. Glossy leaves that are greyed yellow in color with distinct medium and dark green-colored longitudinal stripes, dark green-colored margins and purplish red-colored apices; upper (younger) leaves are mostly purplish deep red in color; flower development is not required for purplish red color development.
  • 4. Good interiorscape and landscape performance.

Plants of the new Neoregelia differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Leaves of plants of the new Neoregelia have stable variegation whereas leaves of plants of the female parent selection do not have stable variegation.
  • 2. Leaves of plants of the new Neoregelia develop purplish red coloration without flower development whereas flowering is required for orange coloration to develop on leaves of plants of the female parent selection.

Plants of the new Neoregelia differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Leaves of plants of the new Neoregelia begin to develop purplish red coloration about four months after planting whereas leaves of plants of the male parent selection begin to develop purplish red coloration after about twelve months after planting.
  • 2. Plants of the new Neoregelia and the male parent selection differ in leaf color as plants of the new Neoregelia are greyed yellow in color with distinct medium and dark green-colored longitudinal stripes, dark green-colored margins and purplish red-colored apices whereas leaves of plants of the male parent selection are solid green in color.

Plants of the new Neoregelia can be compared to plants of the Neoregelia carolinae X (Neoregelia macrosepala x Neoregelia meyendorfii) ‘Magnifica’, disclosed in U.S. Plant Pat. No. 27,215. In side-by-side comparisons, plants of the new Neoregelia and ‘Magnifica’ differ primarily in the following characteristics:

• • 1. Leaves of plants of the new Neoregelia develop purplish red coloration earlier than and without flower development whereas flowering is required for coloration to develop on leaves of plants of ‘Magnifica’.
  • 2. Plants of the new Neoregelia and ‘Magnifica’ differ in leaf color as plants of the new Neoregelia are greyed yellow in color with distinct medium and dark green-colored longitudinal stripes, dark green-colored margins and purplish red-colored apices whereas leaves of plants of ‘Magnifica’ are yellowish white in color with distinct medium green-colored stripes and dark-green margins.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Neoregelia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Neoregelia plant. The photograph is a top perspective view of a typical flowering plant of ‘Minerva’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe flowering plants grown during the spring in 15-cm containers in a polypropylene-covered greenhouse in Princeton, Fla. and under cultural practices typical of commercial Neoregelia production. During the production of the plants, day temperatures ranged from 28° C. to 30° C., night temperatures ranged from 18° C. to 22° C. and light levels averaged 2,500 foot-candles. Plants were twelve months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
