Facts

Summer-cypress is a Eurasian native introduced to North America. It has become an agricultural weed, showing some herbicide resistance, but has also been used to revegetate disturbed sites and as erosion control. It is used in traditional medicine and has been clinically shown to have anti-ulcer properties.
