Anthurium plant named ‘Red Queen’

Abstract

A distinct cultivar of Anthurium plant named ‘Red Queen’, characterized by its upright and outwardly spreading plant habit; freely clumping growth habit; large dark green leaves that are ovate to lanceolate in shape; numerous spathes that are positioned upright and beyond the foliage on strong and erect scapes; large, durable, glossy red spathes; year-round continuous flowering; good flowering performance under low light conditions; and good post-production longevity.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the cultivar name ‘Red Queen’.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create and develop new Anthurium cultivars that have a freely clumping growth habit, strong and vigorous plant growth, attractive spathe color, numerous inflorescences and leaves, and good post-production longevity.

The new Anthurium originated from a cross by the Inventor in October, 1994 of the Inventor's proprietary Anthurium andreanum selection code number 92-4 as the female, or seed, parent with the Inventor's proprietary Anthurium andreanum selection code number 94-3 as the male, or pollen, parent. The cultivar ‘Red Queen’ was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands in January, 1997.

Asexual propagation of the new culitvar by tissue culture in a laboratory in Belgium has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

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

1. Upright and outwardly spreading plant habit.

2. Freely clumping growth habit.

3. Large dark green leaves that are ovate to lanceolate in shape.

4. Numerous spathes that are positioned upright and beyond the foliage on strong and erect scapes.

5. Large, durable, glossy red spathes.

6. Year-round continuous flowering.

7. Good flowering performance under low light conditions.

8. Good post-production longevity.

The new Anthurium can be compared to the female parent, the Inventor's proprietary selection code number 92-4. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code number 92-4 in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the selection code number 92-4.

2. Plants of the new Anthurium have larger leaves than plants of the selection code number 92-4.

3. Plants of the new Anthurium have larger spathes than plants of the selection code number 92-4.

The new Anthurium can be compared to the male parent, the Inventor's proprietary selection code number 94-3. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code number 94-3 in the following characteristics:

1. Plants of the new Anthurium are less compact than plants of the selection code number 94-3.

2. Plants of the new Anthurium grow faster than plants of the selection code number 94-3.

3. Plants of the new Anthurium do not have as durable leaves as plants of the selection code number 94-3.

4. Plants of the new Anthurium have red-colored spathes whereas plants of the selection code number 94-3 have pink-colored spathes.

The new Anthurium can be compared to the Anthurium cultivar ‘Eveline’, disclosed in U.S. Plant Pat. No. 10,970. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the cultivar ‘Eveline’ in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the cultivar ‘Eveline’.

2. Plants of the new Anthurium have darker green leaves than plants of the cultivar ‘Eveline’.

3. Plants of the new Anthurium have smaller spathes than plants of the cultivar ‘Eveline’.

4. Plants of the new Anthurium and of the cultivar ‘Eveline’ differ in spathe coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Anthurium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph comprises a top perspective view of a typical potted plant of the cultivar ‘Red Queen’. Leaf, spathe and spadix colors in the photograph may appear different from the actual colors due to light reflectance.
