Abstract

A new and distinct cultivar of Sanvitalia plant named ‘Wessacomp’, characterized by its compact and mostly upright, low mounding plant habit; small dark green-colored leaves; freely branching habit and short internodes; dense and bushy plant form; freely flowering habit; and bright yellow-colored ray florets.

Description

Botanical designation: Sanvitalia speciosa.

Variety denomination: ‘Wessacomp’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Sanvitalia plant, botanically known as Sanvitalia speciosa and hereinafter referred to by the name ‘Wessacomp’.

The new Sanvitalia was discovered by the Inventor in 2002 as a naturally-occurring whole plant mutation of the Sanvitalia speciosa cultivar Aztekengold, not patented, in a controlled environment in Südlohn, Germany. Specifically, the claimed plant originated as a cutting from the cultivar ‘Aztekengold’ that exhibited desirable, mutated characteristics. The new Sanvitalia was selected by the Inventor on the basis of its compact plant habit.

Asexual reproduction of the new Sanvitalia by vegetative cuttings was first conducted in Südlohn, Germany in 2002. Asexual reproduction by vegetative cuttings has shown that the unique features of this new Sanvitalia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Wessacomp has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wessacomp’. These characteristics in combination distinguish ‘Wessacomp’ as a new and distinct Sanvitalia:

- 1. Compact and mostly upright, low mounding plant habit.
- 2. Small dark green-colored leaves.
- 3. Freely branching habit and short internodes; dense and bushy plant form.
- 4. Freely flowering habit.
- 5. Bright yellow-colored ray florets.

Compared to plants of the parent, the cultivar Aztekengold, plants of the new Sanvitalia are more compact, more upright and have shorter internodes.

Plants of the new Sanvitalia can be compared to plants of the Sanvitalia cultivar Santanis, disclosed in U.S. Plant Pat. No. 14,924. In side-by-side comparisons conducted in Südlohn, The Netherlands, plants of the new Sanvitalia differed from plants of the cultivar Santanis in the following characteristics:

- 1. Plants of the new Sanvitalia were more compact than plants of the cultivar Santanis.
- 2. Plants of the new Sanvitalia had shorter internodes than plants of the cultivar Santanis.
- 3. Plants of the new Sanvitalia had smaller leaves than plants of the cultivar Santanis.

Plants of the new Sanvitalia can also be compared to plants of the Sanvitalia cultivar Wessastar, disclosed in U.S. Plant Pat. No. 14,799. In side-by-side comparisons conducted in Südlohn, The Netherlands, plants of the new Sanvitalia differed from plants of the cultivar Wessastar in the following characteristics:

- 1. Plants of the new Sanvitalia were more compact than plants of the cultivar Wessastar.
- 2. Plants of the new Sanvitalia had shorter internodes than plants of the cultivar Wessastar.
- 3. Plants of the new Sanvitalia had smaller leaves than plants of the cultivar Wessastar.
- 4. Plants of the new Sanvitalia had smaller sepals than plants of the cultivar Wessastar.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Wessacomp’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of a typical inflorescence of ‘Wessacomp’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Südlohn, Germany, under commercial practice during the spring and summer in a glass-covered greenhouse with day temperatures ranging from 20 to 25° C. and night temperatures ranging from 16 to 18° C. Plants used for the photographs and botanical description were grown in 10-cm containers for about 20 weeks.

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.
