plant named ‘Lilliput’

Abstract

A new and distinct cultivar of Aglaonema plant named ‘Lilliput’, characterized by its compact and outwardly arching plant habit; freely clumping habit; relatively short internodes; dense and bushy growth habit; and narrowly lanceolate leaves with dark green and silver-colored markings and dark green-colored margins.

Description

Botanical designation: Aglaonema hybrida.

Cultivar denomination: ‘Lilliput’.

BACKGROUND OF THE INVENTION

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

The new Aglaonema is the product of a controlled breeding program conducted by the Inventors in Chamrajpet, Bangalore, India. The objective of the breeding program is to create new full and compact Aglaonema cultivars with good plant vigor, interesting and unique leaf forms and coloration, resistance to pathogens and pests, and tolerance to low temperatures.

The new Aglaonema plant is the product of a cross-pollination conducted by the Inventors on Feb. 21, 1995 of Aglaonema commutatum var. picturatum ‘Silver Ribbons’, disclosed in U.S. Plant Pat. No. 12,985, as the female, or seed, parent with an unnamed selection of Aglaonemaphilippinense var. stenophyllum, not patented, as the male, or pollen, parent. The new Aglaonema plant was discovered and selected by the Inventors in January, 1997 as a single plant from within the resultant progeny of the stated cross-pollination in a controlled environment in Chamrajpet, Bangalore, India.

Asexual reproduction of the new Aglaonema plant by cuttings and divisions in a controlled environment in Chamrajpet, Bangalore, India since April, 1997 has shown that the unique features of this new Aglaonema 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. The phenotype may vary somewhat with variations in environment 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 ‘Lilliput’. These characteristics in combination distinguish ‘Lilliput’ as a new and distinct cultivar of Aglaonema:

• • 1. Compact and outwardly arching plant habit.
  • 2. Freely clumping habit.
  • 3. Relatively short internodes; dense and full growth habit.
  • 4. Narrowly lanceolate leaves with dark green and silver-colored markings and dark green-colored margins.

Plants of the new Aglaonema differ from plants of the female parent, ‘Silver Ribbons’, in the following characteristics:

• • 1. Plants of the new Aglaonema are smaller and more compact than plants of ‘Silver Ribbons’.
  • 2. Leaves of plants of the new Aglaonema are more narrow than leaves of plants of ‘Silver Ribbons’.
  • 3. Plants of the new Aglaonema have shorter petioles than plants of ‘Silver Ribbons’.
  • 4. Plants of the new Aglaonema and ‘Silver Ribbons’ differ in leaf coloration.

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

• • 1. Plants of the new Aglaonema are smaller and more compact than plants of the male parent selection.
  • 2. Plants of the new Aglaonema are more freely clumping than plants of the male parent selection.
  • 3. Plants of the new Aglaonema and the male parent selection differ in leaf coloration.

Plants of the new Aglaonema can be compared to plants of the Aglaonema hybrida ‘Black Lance’, disclosed in U.S. Plant Pat. No. 10,280. In side-by-side comparisons conducted in Chamrajpet, Bangalore, India, plants of the new Aglaonema differed from plants of ‘Black Lance’ in the following characteristics:

• • 1. Plants of the new Aglaonema were more compact than plants of ‘Black Lance’.
  • 2. Plants of the new Aglaonema were more outwardly arching than and not as upright as plants of ‘Black Lance’.
  • 3. Plants of the new Aglaonema had smaller leaves than plants of ‘Black Lance’.
  • 4. Plants of the new Aglaonema and ‘Black Lance’ differed in leaf coloration.

Plants of the new Aglaonema can be compared to plants of the Aglaonema hybrida ‘White Lance’, disclosed in U.S. Plant Pat. No. 11,053. In side-by-side comparisons conducted in Chamrajpet, Bangalore, India, plants of the new Aglaonema differed from plants of ‘White Lance’ in the following characteristics:

• • 1. Plants of the new Aglaonema were more compact than plants of ‘White Lance’.
  • 2. Plants of the new Aglaonema had smaller leaves than plants of ‘White Lance’.
  • 3. Plants of the new Aglaonema and ‘White Lance’ differed in leaf coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Aglaonema. This photograph shows 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 Aglaonema. The photograph is a top perspective view of a typical plant of ‘Lilliput’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 15-cm containers in Miami, Fla. during the summer in a polypropylene-covered shadehouse. 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 27° C. to 37° C., night temperatures ranged from 15° C. to 26° C. and light levels averaged 1,500 foot-candles. Plants had been growing for 15 months when the photograph and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
