Abstract: A new and distinct cultivar of Verbena plant named `Rap Burg Two`, characterized by its compact, low and outwardly spreading, and decumbent plant habit; freely branching habit; early and uniform flowering habit and dark red purple-colored flowers.
Claim: It is claimed:

1. A new and distinct cultivar of Verbena plant named `Rap Burg Two`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Verbena hybrida.times.Verbena tenuisecta cultivar Rap Burg Two.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida.times.Verbena tenuisecta, and hereinafter referred to by the name `Rap Burg Two`.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Gilroy, Calif. The objective of the breeding program is to develop new compact Verbena cultivars with early and uniform flowering, good basal branching,attractive flower and foliage coloration, and tolerance to Powdery Mildew.

The new Verbena originated from a cross-pollination made by the Inventor in March, 2001 of the Verbena hybrida cultivar Vertis, disclosed in U.S. Plant Pat. No. 12,288, as the female, or seed, parent with a proprietary Verbena tenuisectaselection identified as code number 99-1042-3, not patented, as the male, or pollen, parent. The cultivar Rap Burg Two was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlledenvironment in Gilroy, Calif. in September, 2001.

Asexual reproduction of the new cultivar by terminal cuttings in Gilroy, Calif., since September, 2001 has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Rap Burg Two`. These characteristics in combination distinguish `Rap Burg Two` as a new and distinct cultivar: 1. Compact, low andoutwardly spreading, and decumbent plant habit. 2. Freely branching habit. 3. Early and uniform flowering habit. 4. Dark red purple-colored flowers. 5. Relatively less susceptible to Powdery Mildew.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Verbena differed from plants of the female parent, the cultivar Vertis, in the following characteristics: 1. Plants of the new Verbena were more compact than plants ofthe cultivar Vertis. 2. Plants of the new Verbena and the cultivar Vertis differed in flower coloration as plants of the cultivar Vertis had white-colored flowers.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Verbena differed from plants of the male parent selection in the following characteristics: 1. Plants of the new Verbena had narrower leaves than plants of the maleparent selection. 2. Plants of the new Verbena and the male parent selection differed in flower color as plants of the male parent selection had purple-colored flowers.

The new Verbena can be compared to the cultivar, Esca Burg Two, disclosed in U.S. Plant Pat. No. 13,988. However, in side-by-side comparisons conducted in Gilroy, Calif., plants of the new Verbena differed from plants of the cultivar Esca BurgTwo in the following characteristics: 1. Plants of the new Verbena had shorter internodes than plants of the cultivar Esca Burg Two. 2. Leaves of plants of the new Verbena were smaller and more deeply dissected than leaves of plants of the cultivarEsca Burg Two.

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.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Rap Burg Two`.

The photograph at the bottom of the sheet is a close-up view of typical flower racemes and leaves of `Rap Burg Two`.

Flower and foliage 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 Verbena.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Rap Burg Two have 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 ingenotype. The aforementioned photographs and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice in a polyethylene-covered greenhouse during the summer with day temperatures about 24 to 32.degree. C., night temperatures about 13 to 18.degree. C. and light levels about 2,000 foot-candles. Plants used for the photographs and description were about twelve weeks from planting rooted cuttings and were pinched twice. 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.
