Abstract

A distinct cultivar of Anthurium plant named `Pink Paradise`, characterized by its upright plant habit; freely clumping growth habit; durable dark green leaves that are ovate to lanceolate in shape; numerous inflorescences that are positioned upright and beyond the foliage on strong and erect scapes; durable, glossy pink spathes with light green lobes; year-round continuous flowering; good flowering 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 `Pink Paradise`.
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 self-pollination by the Inventor in August, 1994 of the Inventor's proprietary Anthurium andreanum selection code number 92-7. The cultivar `Pink Paradise` 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 September, 1996.
Asexual propagation of the new cultivar by tissue culture 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 `Pink Paradise`. These characteristics in combination distinguish `Pink Paradise` as a new and distinct cultivar:
1. Upright plant habit.
2. Freely clumping growth habit.
3. Durable dark green leaves that are ovate to lanceolate in shape.
4. Numerous inflorescences that are positioned upright and beyond the foliage on strong and erect scapes.
5. Durable, glossy pink spathes with light green lobes.
6. Year-round continuous flowering.
7. Good flowering under low light conditions.
8. Good post-production longevity.
The new Anthurium can be compared to the parent, the Inventor's proprietary selection code number 92-7. 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 92-7 in the following characteristics:
1. Plants of the new Anthurium have smaller and more durable leaves than plants of the selection code number 92-7.
2. Plants of the new Anthurium have dark pink-colored spathes whereas plants of the selection code number 92-7 have red-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 grow faster than plants of the cultivar `Eveline`.
2. Plants of the new Anthurium have more durable and glossier leaves than plants of the cultivar `Eveline`.
3. Leaf apices of plants of the new Anthurium are more acute than leaf apices of plants of the cultivar `Eveline`.
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 `Pink Paradise`. Leaf, spathe and spadix colors in the photograph may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
