Abstract

A new and distinct cultivar of Anthurium plant named ‘TWYAN0015’, characterized by its upright, outwardly arching and symmetrical plant form; compact growth habit; freely clumping habit; full, dense and bushy appearance; relatively small, glossy and dark green-colored leaves; freely flowering habit; inflorescences positioned at or slightly above foliar plane; and relatively small inflorescences with bright red-colored spathes and creamy white-colored spadices.

Description

Botanical designation: Anthurium hybrida.

Cultivar denomination: ‘TWYAN0015’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium hybrida and hereinafter referred to by the name ‘TWYAN0015’.

The new Anthurium is the result of a planned breeding program conducted by the Inventors in Apopka, Fla. The objective of the breeding program is to create new fast-growing Anthurium cultivars with freely clumping habit, dark green-colored leaves, red-colored spathes and resistance to pathogens.

The new Anthurium originated from a cross-pollination made by the Inventors on Oct. 27, 1999 of the Anthurium hybrida cultivar Cherry Red, disclosed in U.S. Plant Pat. No. 12,315, as the female, or seed, parent with the Anthurium hybrida cultivar Y-14, not patented, as the male, or pollen, parent. The new Anthurium was discovered and selected by the Inventors in August, 2002 as a single plant within the progeny of the stated cross-pollination in a controlled environment in Apopka, Fla. The new Anthurium was selected on the basis of its plant habit and attractive foliage and spathe coloration.

Asexual propagation of the new cultivar by tissue cultured since August, 2002 in a controlled environment in Apopka, Fla., has shown that the unique features of this new Anthurium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TWYAN0015’. These characteristics in combination distinguish ‘TWYAN0015’ as a new and distinct cultivar of Anthurium:

• • 1. Upright, outwardly arching and symmetrical plant form.
  • 2. Compact growth habit.
  • 3. Freely clumping habit; full, dense and bushy appearance.
  • 4. Relatively small, glossy and dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Inflorescences positioned at or slightly above foliar plane.
  • 7. Relatively small inflorescences with bright red-colored spathes and creamy white-colored spadices.

In side-by-side comparisons conducted by the Inventors in Apopka, Fla., plants of the new Anthurium differed from plants of the female parent, the cultivar Cherry Red, in the following characteristics:

• • 1. Plants of the new Anthurium grew faster than plants of the cultivar Cherry Red.
  • 2. Plants of the new Anthurium were more compact than plants of the cultivar Cherry Red.
  • 3. Plants of the new Anthurium were more freely-branching than plants of the cultivar Cherry Red.
  • 4. Plants of the new Anthurium had smaller leaves than plants of the cultivar Cherry Red.
  • 5. Plants of the new Anthurium and the cultivar Cherry Red differed in leaf coloration.
  • 6. Plants of the new Anthurium were more freely and earlier flowering than plants of the cultivar Cherry Red.
  • 7. Inflorescences of plants of the new Anthurium had smaller spathes than inflorescences of plants of the cultivar Cherry Red.

In side-by-side comparisons conducted by the Inventors in Apopka, Fla., plants of the new Anthurium differed from plants of the male parent, the cultivar Y-14, in the following characteristics:

• • 1. Plants of the new Anthurium grew faster than plants of the cultivar Y-14.
  • 2. Plants of the new Anthurium were more compact than plants of the cultivar Y-14.
  • 3. Plants of the new Anthurium were more freely-branching than plants of the cultivar Y-14.
  • 4. Plants of the new Anthurium had smaller leaves than plants of the cultivar Y-14.
  • 5. Plants of the new Anthurium and the cultivar Y-14 differed in leaf coloration.
  • 6. Plants of the new Anthurium were more freely and earlier flowering than plants of the cultivar Y-14.
  • 7. Inflorescences of plants of the new Anthurium had smaller spathes than inflorescences of plants of the cultivar Y-14.

Plants of the new Anthurium can be compared to plants of the cultivar Small Talk, not patented. In side-by-side comparisons conducted in Apopka, Fla., plants of the new Anthurium differed from plants of the Anthurium cultivar Small Talk in the following characteristics:

• • 1. Plants of the new Anthurium grew faster than plants of the cultivar Small Talk.
  • 2. Plants of the new Anthurium were more freely branching than plants of the cultivar Small Talk.
  • 3. Plants of the new Anthurium were more freely flowering than plants of the cultivar Small Talk.

DETAILED BOTANICAL DESCRIPTION

The cultivar TWYAN0015 has 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 observations and measurements describe plants of the new Anthurium that were grown in 20-cm containers, in Apopka, Fla., in a polypropylene-covered shadehouse with light levels ranged from about 1,500 to 2,500 foot-candles. During the production of the plants, day temperatures were about 23° C. to 32° C. and night temperatures were about 21° C. to 24° C. Plants used for the photographs and description were about 18 months from planting. Color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
