Eucalyptus in the Bathroom

I used the bathroom at my friend Hutch’s apartment and noticed he had hung eucalyptus in his shower. He told me that when it gets wet, the plant brings a nice smell to the air. As a variation on this, I bought fresh eucalyptus from the Melrose Place Farmers Market one Sunday and put it in a vase on the sink. A few months in, it still freshens up when the shower makes the room humid.
