USPP16150P2 - Philodendron plant named ‘Variegated Sport #1’ - Google Patents

Abstract

A new and distinct cultivar of Philodendron plant named ‘Variegated Sport #1’, characterized by its upright and outwardly spreading plant habit; dark burgundy-colored stems; glossy leaves that are initially yellow green with dark reddish brown variegation; and excellent postproduction longevity.

Description

Botanical classification/cultivar designation: Philodendron hybrid cultivar Variegated Sport #1.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Philodendron plant, botanically known as Philodendron hybrid, and hereinafter referred to by the name ‘Variegated Sport #1’.

The new Philodendron is a naturally-occurring whole plant mutation of the Philodendron hybrid cultivar Prince of Orange, disclosed in U.S. Plant Pat. No. 6,797. The new Philodendron was discovered by the Inventor in a controlled environment in Apopka, Fla., as a single plant within a group of plants of ‘Prince of Orange’ during the summer of 2000. The selection of this plant was based on its uniquely-colored leaves.

Asexual propagation of the new cultivar by stem cuttings and tissue culture in a controlled environment in Apopka, Fla., since the spring of 2002, has shown that the unique features of this new Philodendron plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Philodendron 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 Variegated Sport #1. These characteristics in combination distinguish ‘Variegated Sport #1’ as a new and distinct cultivar:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Dark burgundy-colored stems.
  • 3. Glossy leaves that are initially yellow green with dark reddish brown variegation.
  • 4. Excellent postproduction longevity.

Plants of the new Philodendron are most similar to plants of the parent, the cultivar Prince of Orange. Plants of the new Philodendron differ primarily from plants of the cultivar Prince of Orange in developing leaf coloration as plants of the cultivar Prince of Orange have young leaves that are dark bronze in color.

Plants of the new Philodendron can also be compared to plants of the cultivar Pastel Sport #2, disclosed in a U.S. Plant patent application Ser. No. 10/949,932. In side-by-side comparisons conducted in Apopka, Fla. plants of the new Philodendron differed from plants of the cultivar Pastel Sport #2 primarily in leaf coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Philodendron, 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 Philodendron.

The photograph on the first sheet comprises a top perspective view of a typical plant of the cultivar Variegated Sport #1 grown in a container.

The photograph on the second sheet comprises a top perspective view of a typical plant of the parent, the cultivar Prince of Orange, grown in a container.

The photograph on the third sheet comprises a close-up view of the lower surfaces of a fully expanded leaf (left) and a developing leaf (right) of the cultivar Variegated Sport #1.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and the following observations and measurements describe eight-month old plants grown in 20-cm containers in Apopka, Fla., in a polyethylene-covered greenhouse with day temperatures of 21 to 32° C., night temperatures of 21 to 29° C., and light levels about 1,500 foot-candles.
