Claims

1. A new and distinct variety of Scaevola plant named ‘Luedansca’ characterized by the following combination of characteristics: (a) forms true blue colored flowers, (b) displays medium to dark green colored foliage, and (c) exhibits a moderately vigorous, compact, mounded growth habit; substantially as herein shown and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant and plant parts of the new variety. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘Luedansca’ variety. The plants were grown in three-gallon pots for approximately three years at Arroyo Grande, Calif. Photographs were taken in April 2021.

(5) The new ‘Luedansca’ variety has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
