[Wikipedia] Ecology: Pollinators of V. serpyllifolia include flies and bees that visit the flowers for nectar. The seeds can be dispersed by attaching onto the wings of birds or the fur of some animals. Veronica serpyllifolia seeds were found in cattle dung, thus cattle or other grazers are likely important dispersers of the plant. (link added by Mary Ann Machi)
