plant named ‘Key Largo’

Abstract

A new and distinct cultivar of Neoregelia plant named ‘Key Largo’, characterized by its broad and outwardly spreading growth habit; leaves that are close to horizontal in aspect; leaves that are dark green in color with distinct light yellow green-colored stripes and margins; when flowering, upper leaves are red purple in color; good interiorscape and landscape performance; and relative resistance to pathogens common to Neoregelia plants.

Description

Botanical designation: Neoregelia carolinae×(Neoregelia meyendorfii×Neoregelia macrosepala).

Cultivar denomination: ‘KEY LARGO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Neoregelia plant, botanically known as Neoregelia carolinae×(Neoregelia meyendorfii×Neoregelia macrosepala), and hereinafter referred to by the name ‘Key Largo’.

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 2006 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 meyendorfii×Neoregelia macrosepala, 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 2006.

Asexual reproduction of the new Neoregelia plant by offsets in a controlled environment in Princeton, Fla. since 2007, 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 ‘Key Largo’. These characteristics in combination distinguish ‘Key Largo’ as a new and distinct Neoregelia plant:

• • 1. Broad and outwardly spreading growth habit.
  • 2. Leaves that are close to horizontal in aspect.
  • 3. Leaves that are dark green in color with distinct light yellow green-colored stripes and margins; when flowering, upper leaves are red purple in color.
  • 4. Good interiorscape and landscape performance.
  • 5. Relatively resistant to pathogens common to Neoregelia plants.

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

• • 1. Plants of the new Neoregelia are broader than plants of the female parent selection.
  • 2. Leaves of plants of the new Neoregelia are more horizontal than and not as arching as leaves of plants of the female parent selection.
  • 3. Plants of the new Neoregelia and the female parent selection differ in leaf color as plants of the female parent selection are variegated.
  • 4. Flowering plants of the new Neoregelia and the female parent selection differ in upper leaf color as flowering plants of the female parent selection have orange-colored upper leaves.

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

• • 1. Plants of the new Neoregelia and the male parent selection differ in leaf color as plants of the male parent selection have green-colored leaves that are tinged with red.
  • 2. Flowering plants of the new Neoregelia and the male parent selection differ in upper leaf color as flowering plants of the male parent selection have red-colored upper leaves.

Plants of the new Neoregelia can be compared to plants of the Neoregelia carolinae ‘Flandria’, not patented. In side-by-side comparisons conducted in Princeton, Fla., plants of the new Neoregelia and ‘Flandria’ differed primarily in the following characteristics:

• • 1. Plants of the new Neoregelia are broader than plants of ‘Flandria’.
  • 2. Leaves of plants of the new Neoregelia are more horizontal than and not as arching as leaves of plants of ‘Flandria’.
  • 3. Leaf coloration pattern of plants of the new Neoregelia is more stable than leaf coloration pattern of plants of ‘Flandria’.
  • 4. Flowering plants of the new Neoregelia and ‘Flandria’ differ in upper leaf color as flowering plants of ‘Flandria’ have red orange-colored upper leaves.
