Sorry to use the same shot again.  It's still the best I did on that occasion.  Sticky campion produces chemicals that strengthen the immune systems of its neighbors.  To bad it doesn't work for animals.  It's a little puzzling to me why this ability would be an advantage for the catchfly.  It seems like it would be helping the competitors.  Could help for the neighbors be incidental to what the chemicals do for the campion?  After all, successful adaptations all start out as accidents.  Or maybe it's because sticky grows in rocky areas, so perhaps healthy neighbors improve the neighborhood, building up more organic material in the soil.  Or could there be other explanations?
