Which group of herbs is noted as being left alone by some ground squirrels, similar to the general avoidance of Asters?
Answer
Rosemary, sage, thyme, and lemon verbena
Asters are generally considered safe because they are often avoided by pests, similar to how certain strongly scented herbs are treated by ground squirrels. The text specifically names rosemary, sage, thyme, and lemon verbena as examples of herbs that certain ground squirrels were noted as leaving alone. This shared characteristic—having scents or textures that repel or discourage investigation—is why asters are grouped with them and plants like black-eyed Susans when discussing natural repellency against various mammals in the garden ecosystem.
