The colorful illustration shows several species of nasturtium (Tropaeolum) and pansies (Viola tricolor) with their characteristic flower shapes. Yellow, orange, red, and blue flowers are depicted, featuring the typical five petals of pansies and the rounded leaves and funnel-shaped flowers of nasturtiums. Both plant species are not only popular as ornamental plants but also edible – nasturtium is used in salads for its sharp, cress-like taste..
