A number of insects feed on and in this plant. Look for swellings in the plant stems caused my minute flies called Gall Midges. Cut the frest galls open to find the small orange larvae responsible.
LEAVES: The slightest brush against this plant will permeate the air
with curious aroma - pleasant or quite unpleasant depending on the observer.
Leaves are linear and grass like. They are smooth and shiny. Under
magnification (10x loop) the translucent oil glands can be seen easily.
