Abstract: A new and distinct cultivar of Oxalis plant named `Jroxblavel`, characterized by its upright, outwardly spreading and uniformly mounded plant habit; numerous basal leaves; dense and bushy plant form; freely flowering habit; black-colored foliage; and white-colored flowers.
Claim: It is claimed:

1. A new and distinct cultivar of Oxalis plant named `Jroxblavel`, as illustrated and described.
Description: Botanicaldesignation: Oxalis regnellii.

Cultivar denomination: `Jroxblavel`.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Oxalis plant, botanically known as Oxalis regnellii, and hereinafter referred to by the cultivar name `Jroxblavel`.

The new Oxalis is a product of a planned breeding program conducted by the Inventor in Szombathely, Hungary. The objective of the program is to create new Oxalis cultivars with attractive foliage and flower colors.

The new Oxalis originated from a cross-pollination made by the Inventor in 1993 of two unnamed selections of Oxalis regnellii, not patented. The new Oxalis was discovered and selected from the resultant progeny of the stated cross-pollination bythe Inventor in a controlled environment in Szombathely, Hungary in 2001.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Szombathely, Hungary since the summer of 2002, has shown that the unique features of this new Oxalis are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the cultivar Jroxblavel have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Jroxblavel`. These characteristics in combination distinguish `Jroxblavel` as a new and distinct cultivar of Oxalis: 1. Upright,outwardly spreading and uniformly mounded plant habit. 2. Numerous basal leaves; dense and bushy plant form. 3. Freely flowering habit. 4. Black-colored foliage. 3. White-colored flowers.

Plants of the new Oxalis differ primarily from plants of the parent selections in the following characteristics: 1. Plants of the new Oxalis have black-colored foliage whereas plants of the parent selections have green-colored foliage. 2. Plants of the new Oxalis are more freely flowering than plants of the parent selections.

Plants of the new Oxalis can be compared to plants of the cultivar Deep Purple, not patented. In side-by-side comparisons conducted in Southern California, plants of the new Oxalis differed from plants of the cultivar Deep Purple primarily inleaf color as plants of the cultivar Deep Purple had red purple-colored leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Oxalis.

The photograph at the top of the sheet is a close-up view of typical flowers and leaves of `Jroxblavel`.

The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of `Jroxblavel` grown in a container.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in one gallon were used for theaforementioned photographs and following description. Plants were about 16 weeks from planting rooted cuttings. Plants were grown under conditions which closely approximate commercial production conditions during the spring in Bonsall, Calif. in apolyethylene-covered greenhouse.
