Description

Latin name of the genus and species: Portulaca oleraea.

Variety denomination: ‘PHSFR11-0’.

BACKGROUND OF THE INVENTION

The new Portulaca cultivar is a product of chance discovery by the inventor, Steve Jones, at a commercial greenhouse in Santa Paula, Calif. The breeder discovered an interesting, naturally occurring branch mutation in a planting of unnamed, unpatented Portulaca oleraea.

The branch mutation showed bi-color foliage on a plant which was otherwise entirely green in foliage color. This discovery was made during May of 2015.

Asexual reproduction of the new cultivar was first performed by vegetative terminal cuttings. at the same commercial greenhouse in Santa Paula, Calif. in August of 2015. Subsequent propagation and growing the plants over a period of several months shows the variegation pattern is expressed as both bi-color and tricolor. The variegation pattern has shown consistency and stability over the course of three propagative generations.

SUMMARY OF THE INVENTION

The cultivar ‘PHSFR11-0’ 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 ‘PHSFR11-0’ These characteristics in combination distinguish ‘PHSFR11-0’ as a new and distinct Portulaca cultivar:

    • 1. Unique variegated foliage which can be bi-color or tri-color.
    • 2. Low spreading and dense plant habit.
    • 3. Bright pink flowers.

PARENTAL COMPARISON

Plants of the new cultivar ‘PHSFR11-0’ are similar in most horticultural characteristics to the parent variety. However, the new variety differs in the following:

    • 1. Leaves or the new variety are variegated, foliage of the parent is solid green.
    • 2. Stems of the new variety are flushed pink, stems of the parent are green.
    • 3. Plant vigor of the new variety is less than vigor of the parent.
    • 4. Foliage size of the new variety is smaller than foliage of the parent.

COMMERCIAL COMPARISON

To the best of the inventor's knowledge, the new variety is the only Portulaca oleracea plant with variegation and a dense, low growing plant form. Plants of the new cultivar ‘PHSFR11-0’ can however be compared to the unpatented commercial Portulaca ‘Cupcakes Grape Jelly’. The two Portulaca varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

    • 1. Leaves or the new variety are variegated, foliage of the comparator is solid green.
    • 2. Stems of the new variety are flushed pink, stems of the comparator are green.
    • 3. Plant habit of the new variety is low growing a spreading, while the plant habit of ‘Cupcakes Grape Jelly’ is semi-upright.

Plants of the new cultivar ‘PHSFR11-0’ can also be comparable to the unpatented commercial variety can also be comparable to the patented commercial variety Portulaca ‘SAKPOR001’ U.S. Plant Pat. No. 24,528. The two Portulaca varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

    • 1. Leaves or the new variety are variegated, foliage of the comparator is solid green.
    • 2. Stems of the new variety are flushed pink, stems of the comparator are green.
    • 3. Plant habit of the new variety is low growing a spreading, while the plant habit of the comparator is semi-upright and semi-mounding.
    • 3. Plant vigor of the new variety is moderate; this comparator has a vigorous growth habit.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PHSFR11-0’ grown in a greenhouse, in Santa Paula, Calif. in a 10 inch basket. Age of the plant photographed is approximately 20 weeks from a rooted cutting.

FIG. 2 illustrates a close up of the foliage.

The photographs were 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.
