Calla is a pattern hand-painted by Anna Kowalczyk, creator of the Arte Annowa Collection. Calla is considered a noble flower, imbuing positive energy and calming. The ever-popular tropical leaf motifs are contrasted with the delicacy and elegance of a white calla. The image has been presented in a modern, large-format wallpaper. The pattern is bottle green, with occasional touches of white flowers, perfectly in keeping with current design trends.
