plant named ‘Mona Lisa’

Abstract

A new and distinct cultivar of Neoregelia plant named ‘Mona Lisa’, characterized by its upright and outwardly arching growth habit; leaves that are dark green in color with cream-colored stripes and dark-green margins; upper leaves, proximally, rosy red in color; and good interiorscape and landscape performance.

Description

Botanical designation: Neoregelia carolinae×Neoregelia×hybrida.

Cultivar denomination: ‘MONA LISA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Neoregelia plant, botanically known as Neoregelia carolinae×Neoregelia×hybrida, and hereinafter referred to by the name ‘Mona Lisa’.

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 2002 in Princeton, Fla. of an unnamed proprietary selection of Neoregelia carolinae, not patented, as the female, or seed, parent with Neoregelia×hybrida ‘Passion’, 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 2003.

Asexual reproduction of the new Neoregelia plant by offsets in a controlled environment in Princeton, Fla. since 2003, 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 ‘Mona Lisa’. These characteristics in combination distinguish ‘Mona Lisa’ as a new and distinct Neoregelia plant:

• • 1. Upright and outwardly arching growth habit.
  • 2. Leaves that are dark green in color with cream-colored stripes and dark-green margins; upper leaves, proximally, rosy red in color.
  • 3. Good interiorscape and landscape performance.

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

• • 1. Leaf coloration of plants of the new Neoregelia is more stable than leaf coloration of plants of the female parent selection.
  • 2. Plants of the new Neoregelia and the female parent selection differ in leaf color as plants of the female parent selection have orange-colored leaves.

Plants of the new Neoregelia differ primarily from plants of the male parent, ‘Passion’, in the following characteristics:

• • 1. Plants of the new Neoregelia have shorter leaves than plants of ‘Passion’.
  • 2. Plants of the new Neoregelia and ‘Passion’ differ in leaf color as plants of ‘Passion’ have green-colored leaves.

Plants of the new Neoregelia can be compared to plants of the Neoregelia ‘Raphael’, disclosed in U.S. Plant Pat. No. 10,719. In side-by-side comparisons conducted in Princeton, Fla., plants of the new Neoregelia and ‘Raphael’ differed primarily in the following characteristics:

• • 1. Plants of the new Neoregelia were more compact than plants of ‘Raphael’.
  • 2. Plants of the new Neoregelia and ‘Raphael’ differed in leaf color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe flowering plants grown during the spring and summer 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 3,200 foot-candles. Plants were 13 months old when the photographs and description were taken.
