The Plant that Hides from Humans…

Fritillaria Delavayi grows in the hillsides of China in the Hengduan mountains and in Nepal. It has been used for over 2,000 years for medicinal purposes. The plant is believed to have properties that can treat coughs and other respiratory ailments. What this plant has done is evolve to the point where it can change its color to blend in with its environment in much the same way as reptiles do. This is in response to the over harvesting of the plant and its attempt to survive. The over harvesting of the plant is the result of the high price it now brings on the market. Since the plant is not threatened by any animal that feeds on it, scientists determined that this is a defense mechanism against humans. In areas where it is not threatened it has a bright yellow flower and green leaves. In heavily harvested areas it can change to blend in with rocks. Since it only blooms every 5 years it is difficult to find and harvest the bulb of the plant. This is not the first time humans have had an effect on plant life. Until recently, this was not even considered.
