1. A new and distinct cultivar of Anthurium plant named ‘True Love’, as illustrated and described.

Description:
Botanical classification/cultivar designation: Anthurium andreanum cultivar ‘True Love’.

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 name ‘True Love’.

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 compact, freely clumping and freely flowering Anthurium cultivars with strong roots, dark green leaves, attractive spathe color, and good inflorescence longevity.

The new Anthurium originated from a cross by the Inventor in 1999 of a proprietary selection of Anthurium andreanum identified as code number 9515, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 9715, not patented, as the male, or pollen, parent. The cultivar True Love was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands in July, 2000.

Asexual propagation of the new cultivar by meristem culture in a laboratory in Belgium since July, 2000, 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 ‘True Love’. These characteristics in combination distinguish True Love as a new and distinct cultivar:

1. Upright and outwardly spreading plant habit.

2. Freely clumping growth habit.

3. Durable dark green leaves.

4. Red-colored spathes with yellow orange-colored spadices that are positioned slightly above and beyond the foliage on strong and erect scapes.

5. Freely flowering habit.

6. Good inflorescence longevity.

Plants of the new Anthurium can be compared to plants of the female parent, the proprietary selection identified as code number 9515. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differed from plants of the selection 9515 in the following characteristics:

1. Plants of the new Anthurium were more compact than plants of the selection 9515.

2. Plants of the new Anthurium and the selection 9515 differed in spathe coloration as plants of the selection 9515 had white, red and green tri-colored spathes.

Plants of the new Anthurium can be compared to plants of the male parent, the selection 9715. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differed from plants of the selection 9715 in the following characteristics:

1. Plants of the new Anthurium had darker green-colored leaves than plants of the selection 9715.

2. Plants of the new Anthurium and the selection 9715 differed in spathe coloration as plants of the selection 9715 had orange-colored spathes.

Plants of the new Anthurium can be compared to plants of the cultivar ‘Red Love’, disclosed in U.S. Plant Pat. No. 11,005. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium different from plants of the cultivar Red Love in the following characteristics:

1. Plants of the new Anthurium had flatter and fleshier leaves than plants of the cultivar Red Love.

2. Spathes of plants of the new Anthurium were flatter, thicker and more red in color than spathes of plants of the cultivar Red Love.

3. Spathes of plants of the new Anthurium turned green in color more slowly than spathes of plants of the cultivar ‘Red Love’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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. 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 Anthurium.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of the cultivar ‘True Love’.

The photograph on the second sheet comprises a close-up view of typical inflorescences of ‘True Love’.
