A new and distinct cultivar of Sanvitalia plant named ‘Duesansugo’, characterized by its compact and mounding plant habit; vigorous growth habit; early and freely flowering habit; and inflorescences with bright yellow-colored ray florets.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofSanvitaliaplant, botanically known asSanvitalia procumbens, and hereinafter referred to by the name ‘Duesansugo’.

The newSanvitaliaplant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact and moundingSanvitaliacultivars with numerous inflorescences.

The newSanvitaliaplant originated from an open-pollination in Rheinberg, Germany in July, 2007, of a proprietary selection ofSanvitalia procumbensidentified as code number F-03-21, not patented, as the female, or seed, parent with an unknown selection ofSanvitalia procumbensas the male, or pollen, parent. The newSanvitaliaplant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2008.

Asexual reproduction of the newSanvitaliaplant by vegetative cuttings in a controlled environment in Rheinberg, Germany since May, 2008, has shown that the unique features of this newSanvitaliaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the newSanvitaliahave 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 in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesansugo’. These characteristics in combination distinguish ‘Duesansugo’ as a new and distinct cultivar ofSanvitalia:1. Compact and mounding plant habit.2. Vigorous growth habit.3. Early and freely flowering habit.4. Inflorescences with bright yellow-colored ray florets.

Plants of the newSanvitaliadiffer primarily from plants of the female parent selection in plant habit as plants of the newSanvitaliaare more compact than plants of the female parent selection.

Plants of the newSanvitaliacan be compared to plants ofSanvitalia procumbens‘Aztek Gold’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the newSanvitaliadiffered from plants of ‘Aztek Gold’ in the following characteristics:1. Plants of the newSanvitaliawere more compact than plants of ‘Aztek Gold’.2. Plants of the newSanvitaliahad smaller leaves than plants of ‘Aztek Gold’.3. Plants of the newSanvitaliahad longer peduncles than plants of ‘Aztek Gold’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 10.5-cm containers during the summer in a glass-covered greenhouse in Rheinberg, Germany under conditions and practices which approximate those generally used in commercialSanvitaliaproduction. During the production of the plants, day and night temperatures averaged 18° C. and light levels were about 4,500 lux. Plants were pinched one time three weeks after planting. Plants were 20 weeks old when the photograph and description were taken.
