plant named ‘Bryant Queen’

Abstract

A new and distinct cultivar of Aglaonema plant named ‘Bryant Queen’, characterized by its relatively compact and outwardly arching plant habit; freely clumping habit; dense and full growth habit; narrowly lanceolate leaves with contrasting dark green and silver-colored markings and dark green-colored margins; and relative cold temperature tolerance.

Description

Botanical designation: Aglaonema hybrida.

Cultivar denomination: ‘BRYANT QUEEN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Aglaonema plant, botanically known as Aglaonema hybrida and hereinafter referred to by the name ‘Bryant Queen’.

The new Aglaonema plant is a naturally-occurring whole plant mutation of Aglaonema hybrida ‘Silver Queen’, not patented. The new Aglaonema plant was discovered and selected by the Inventor as a single plant from within a population of plants of ‘Silver Queen’ in a polypropylene-covered shadehouse in Zolfo Springs, Fla. on May 1, 2008.

Asexual reproduction of the new Aglaonema plant by cuttings in a controlled environment in Zolfo Springs, Fla. since May 2, 2008 has shown that the unique features of this new Aglaonema plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Aglaonema have not been observed under all possible 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 ‘Bryant Queen’. These characteristics in combination distinguish ‘Bryant Queen’ as a new and distinct Aglaonema plant:

• • 1. Relatively compact and outwardly arching plant habit.
  • 2. Freely clumping habit.
  • 3. Dense and full growth habit.
  • 4. Narrowly lanceolate leaves with contrasting dark green and silver-colored markings and dark green-colored margins.
  • 5. Relatively cold temperature tolerant.

Plants of the new Aglaonema differ from plants of the parent, ‘Silver Queen’, primarily in cold temperature tolerance as plants of the new Aglaonema are more cold tolerant than plants of ‘Silver Queen’.

Plants of the new Aglaonema can be compared to plants of the Aglaonema hybrida ‘Moonlight Bay’, not patented. In side-by-side comparisons conducted in Zolfo Springs, Fla., plants of the new Aglaonema differed from plants of ‘Moonlight Bay’ in the following characteristics:

• • 1. Plants of the new Aglaonema had smaller leaves than plants of ‘Moonlight Bay’.
  • 2. Plants of the new Aglaonema and ‘Moonlight Bay’ differed in leaf coloration as plants of ‘Moonlight Bay’ had duller and less contrasting coloration.
  • 3. Plants of the new Aglaonema and ‘Moonlight Bay’ differed in petiole coloration as plants of ‘Moonlight Bay’ had solid green-colored petioles.

Plants of the new Aglaonema can also be compared to plants of the Aglaonema hybrida ‘Emerald Bay’, disclosed in U.S. Plant Pat. No. 12,867. In side-by-side comparisons conducted in Zolfo Springs, Fla., plants of the new Aglaonema differed from plants of ‘Emerald Bay’ in the following characteristics:

• • 1. Plants of the new Aglaonema had smaller leaves than plants of ‘Emerald Bay’.
  • 2. Plants of the new Aglaonema and ‘Emerald Bay’ differed in leaf coloration as plants of ‘Emerald Bay’ had duller and less contrasting coloration and a wider dark green-colored margins.
  • 3. Plants of the new Aglaonema and ‘Emerald Bay’ differed in petiole coloration as plants of ‘Emerald Bay’ had solid green-colored petioles.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Aglaonema plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Aglaonema plant.

The photograph on the first sheet is a side perspective view of a typical plant of ‘Bryant Queen’ grown in a container.

The photograph on the second sheet is a close-up view of a typical plant of ‘Bryant Queen’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the early spring in 20-cm containers in a polypropylene-covered shadehouse in Zolfo Springs, Fla. Plants were grown under conditions and practices which approximate those generally used in commercial Aglaonema shadehouse production. During the production of the plants, day temperatures ranged from 29° C. to 35° C., night temperatures ranged from 24° C. to 29° C. and light levels averaged 2,500 foot-candles. Plants were 15 months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
