USPP18013P2 - Syngonium plant named ‘Neon Robusta’ - Google Patents

Abstract

A new and distinct cultivar of Syngonium plant named ‘Neon Robusta’, characterized by its upright and symmetrical plant shape; freely branching growth habit; dense and bushy plant form; and iridescent pink-colored upper leaf surfaces.

Description

Botanical designation: Syngonium podophyllum.

Cultivar denomination: ‘Neon Robusta’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Syngonium plant, botanically known as Syngonium podophyllum and hereinafter referred to by the name ‘Neon Robusta’.

The new Syngonium is a naturally-occurring branch mutation of the Syngonium podophyllum cultivar Neon, not patented. The new Syngonium was discovered and selected by the Inventor on Jun. 6, 2003 in a controlled environment in Apopka, Fla. on a single plant of the cultivar of Neon.

Asexual propagation of the new cultivar by tissue culture since June, 2003, in a controlled environment in Apopka, Fla., has shown that the unique features of this new Syngonium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. Upright and symmetrical plant shape.
  • 2. Freely branching growth habit; dense and bushy plant form.
  • 3. Iridescent pink-colored upper leaf surfaces.

In side-by-side comparisons conducted by the Inventor in Apopka, Fla., plants of the new Syngonium differed primarily from plants of the parent, the cultivar Neon, in leaf color as plants of the cultivar Neon had fainter pink-colored leaves.

Plants of the new Syngonium can be compared to plants of the cultivar Regina, not patented. In side-by-side comparisons conducted in Apopka, Fla., plants of the new Syngonium differed from plants of the Syngonium cultivar Regina in the following characteristics:

• • 1. Plants of the new Syngonium are more compact than plants of the cultivar Regina.
  • 2. Plants of the new Syngonium are more freely branching than plants of the cultivar Regina.
  • 3. Upper leaf surfaces of plants of the new Syngonium are more intense pink in color than upper leaf surfaces of plants of the cultivar Regina.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Neon Robusta’ grown in a container.

The photograph at the top of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Neon Robusta’.

The photograph at the bottom of the second sheet is a close-up view of the lower surface of a typical leaf of ‘Neon Robusta’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Neon Robusta 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 observations and measurements describe plants of the new Syngonium that were grown in 15-cm containers, in Sebring, Fla. in a polycarbonate-covered greenhouse with light levels about 5,000 foot-candles. During the production of the plants, day temperatures ranged from about 21° C. to about 33° C. and night temperatures ranged from about 10° C. to about 20° C. Plants used for the photographs and description were about four months from planting. Color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
