Sniffing Plants

Originally posted on Agritate, which is no longer active.

The alluring odor cast by your enticing neighbor that lifts you up by the nose to float down the hall a la Pepé Le Pew seems to have parallels in the plant kingdom as well.

In Scientific American, a recent article describes how parasitic plants sniff their way toward their prey. I wonder whether certain plants, then, “smell” and grow toward (or away from) compost heaps or other rotting piles of stuff? Plant communication is a vibrant topic—it’d be great to have actual biochemical confirmation of the purported benefits of companion planting in vegetable gardens.
