Anthurium plant named `Mylene`

Abstract

A distinct cultivar of Anthurium plant named `Mylene`, characterized by its compact, outwardly arching and freely branching plant habit; dark green leaves that are glossy and cordate in shape; numerous inflorescences that are positioned above the foliage on strong and erect scapes; broad orange spathes with auriculate base; 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 `Mylene`.

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 new Anthurium cultivars that have a freely branching growth habit, strong plant growth, medium leaf size, rapid growth rate, strong roots, attractive spathe color, numerous inflorescences and good post-production longevity. The new cultivar originated from a cross by the inventor in 1990 of the inventor's proprietary Anthurium andreanum selection code number 6 as the female, or seed, parent with the inventor's proprietary Anthurium andreanum selection code number 3 as the male, or pollen, parent. The cultivar `Mylene` 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.

Asexual propagation by tissue cultures of the new cultivar at Schipluiden, The Netherlands, 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 `Mylene`. These characteristics in combination distinguish `Mylene` as a new and distinct cultivar:

1. Compact, outwardly arching and freely branching growth habit.

2. Dark green leaves that are glossy and cordate in shape.

3. Numerous inflorescences that are positioned above the foliage on strong and erect scapes.

4. Broad orange spathes with auriculate base.

5. Good post-production longevity.

The new Anthurium can be compared to its female parent cultivar, the proprietary selection code number 6. Plants of the new Anthurium are different from plants of selection code number 6 in the following characteristics:

1. Plants of the cultivar `Mylene` have smaller, darker green and stronger leaves than plants of the selection code number 6.

2. Plants of the cultivar `Mylene` are more outwardly spreading than plants of the selection code number 6.

3. Plants of the cultivar `Mylene` have smaller spathes and spadices than plants of the selection code number 6.

4. Plants of the cultivar `Mylene` root faster than plants of the selection code number 6.

The new Anthurium can be compared to its male parent cultivar, the proprietary selection code number 3. Plants of the new Anthurium are different from plants of selection code number 3 in the following characteristics:

1. Plants of the cultivar `Mylene` have larger leaves than plants of the selection code number 3.

2. Plants of the cultivar `Mylene` have larger inflorescences than plants of the selection code number 3.

The new Anthurium can be compared to the Anthurium cultivar `Linda` (disclosed in U.S. Plant Pat. No. 10,706). Plants of the new Anthurium differ from plants of the cultivar `Linda` in the following characteristics:

1. Plants of the cultivar `Mylene` are more compact than plants of the cultivar `Linda`.

2. Plants of the cultivar `Mylene` have shorter and narrower leaves than plants of the cultivar `Linda`.

3. Spathe color of plants of the cultivar `Mylene` is lighter than the spathe color of plants of the cultivar `Linda`.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, 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 `Mylene`. Leaf and flower colors in the photographs may appear different from the actual colors due to light reflectance.
