plant named ‘IPOSGLGRE’

-

A new and distinct Ipomoea cultivar named ‘IPOSGLGRE’ is disclosed, characterized light green, cordate shaped foliage, and a bush forming habit. Additionally the new cultivar flowers under short day conditions and produces many lateral branches, without pinching or chemical growth regulators. The new cultivar is an Ipomoea, typically suited for ornamental container and garden use.

Description

Latin name of the genus and species: Ipomoea batatas.

Variety denomination: ‘IPOSGLGRE’.

BACKGROUND OF THE INVENTION

The new variety originated from a commercial breeding program under the direction of the inventor, Paul A. Talmadge. The crossing resulting in the new cultivar was made in Fall of 2007, with the seed parent, an unpatented, unnamed proprietary seedling and the pollen parent, also an unpatented, unnamed proprietary seedling. The new variety was discovered by the inventor in April of 2008 at a commercial greenhouse in Lompoc, Calif.

After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘IPOSGLGRE’ was first performed in a commercial research greenhouse in Lompoc, Calif. during June of 2008. ‘IPOSGLGRE’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type. Asexual reproduction of the new variety is by vegetative cuttings.

SUMMARY OF THE INVENTION

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

    • 1. Light green foliage
    • 2. Cordate foliage shape.
    • 3. Bush forming habit, short vines formed in mature plants or in high temperatures.
    • 4. Very well branched, without pinching or chemical growth regulator use
    • 5. Short day flowering.

PARENTAL COMPARISON

Plants of the new cultivar ‘IPOSGLGRE’ are similar to the seed parent in most horticultural characteristics. However, ‘IPOSGLGRE’ differs in producing cordate shaped foliage that is characteristically light green in color, whereas the seed parent has palmately shaped, deep purple foliage.

Plants of the new cultivar ‘IPOSGLGRE’ are similar to the pollen parent in most horticultural characteristics. However, ‘IPOSGLGRE’ produces a well-branched, plant with a bush shaped habit whereas the pollen parent has a vining plant habit, with less branching.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘IPOSGLGRE’ are best compared to the commercial variety Ipomoea batatas ‘Sweet Caroline Light Green’ U.S. Plant Pat. No. 15,028. Plants of ‘IPOSGLGRE’ are similar to plants of ‘Sweet Caroline Light Green’ in most horticultural characteristics, however, plants of ‘IPOSGLGRE’ have a different shaped foliage, smaller foliage and better branching characteristics.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘IPOSGLGRE’ grown in a greenhouse in Lompoc, Calif. This plant is approximately 8 weeks old, from an unrooted cutting, shown in a 6 inch pot pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

 DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to Pantone Formula Guide Solid Matte, First Edition 2000-2001, except where general terms of ordinary dictionary significance are used.
