USPP18307P2 - Ipomoea plant named ‘Emerald Splash’ - Google Patents

Abstract

A new and distinct cultivar of Ipomoea plant named ‘Emerald Splash’, characterized by its compact, mounding and outwardly spreading growth habit; freely branching plant habit; light yellow-green and green variegated foliage.

Description

Botanical designation: Ipomoea batatas.

Cultivar denomination: ‘Emerald Splash’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ipomoea, botanically known as Ipomoea batatas, and hereinafter referred to by the name ‘Emerald Splash’.

The new Ipomoea is a product of a planned breeding program conducted by the Inventor in Riverhead, N.Y. The objective of the breeding program is to create new compact Ipomoea cultivars with attractive foliage shape and coloration.

The new Ipomoea is a naturally-occurring whole plant mutation of the Ipomoea batatas cultivar Ivory Jewel, not patented. The new Ipomoea was discovered and selected by the Inventor from within a population of plants of ‘Ivory Jewel’ in a controlled environment in Riverhead, N.Y. on May 4, 2004.

Asexual reproduction of the new Ipomoea by terminal cuttings in a controlled environment in Riverhead, N.Y. since February, 2005, has shown that the unique features of this new Ipomoea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Emerald Splash has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Emerald Splash’. These characteristics in combination distinguish ‘Emerald Splash’ as a new and distinct cultivar of Ipomoea:

• • 1. Compact, mounding and outwardly spreading growth habit.
  • 2. Freely branching plant habit.
  • 3. Light yellow-green and green variegated foliage.

Plants of the new Ipomoea can be compared to plants of the parent, the cultivar Ivory Jewel. Plants of the new Ipomoea differ from plants of the cultivar Ivory Jewel in the following characteristics:

• • 1. Plants of the new Ipomoea are much more compact and less vigorous than plants of the cultivar Ivory Jewel.
  • 2. Plants of the new Ipomoea are more freely branching and have shorter internodes than plants of the cultivar Ivory Jewel.
  • 3. Plants of the new Ipomoea have smaller leaves than plants of the cultivar Ivory Jewel.
  • 4. Plants of the new Ipomoea have light yellow green and green variegated foliage whereas plants of the cultivar Ivory Jewel have less striking yellow green and dark green variegated foliage.

Plants of the new Ipomoea can be compared to plants of the Ipomoea batatas cultivar Ace of Spades, not patented. In side-by-side comparisons conducted in Riverhead, N.Y., plants of the new Ipomoea differed from plants of the cultivar Ace of Spades in the following characteristics:

• • 1. Plants of the new Ipomoea were more compact and less vigorous than plants of the cultivar Ace of Spades.
  • 2. Plants of the new Ipomoea and the cultivar Ace of Spades differed in leaf color as plants of the cultivar Ace of Spades had maroon-colored leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

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

The photograph on the second sheet comprises a side perspective comparison view of typical plants of ‘Emerald Splash’ (left) and ‘Ivory Jewel’ (right).

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Riverhead, N.Y. in a polyethylene-covered greenhouse during the spring and summer under conditions which closely approximate commercial production. During the production of the plants, day temperatures were about 22° C., night temperatures were about 17° C. and light levels ranged from 3,000 to 8,000 foot-candle. Plants were about 14 weeks old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
