This article from a Vietnamese online publication caught our eye.
"This is a special moisture-loving herbaceous plant, with a lifespan of up to 100 years, rather slow growth and found at an altitude of 1,200-2,000m above sea level.
"This plant was discovered by scientists in 1973 and officially announced in 1985 with the name Vietnamese ginseng, a completely new type of ginseng in the scientific world.
"They are found in the mountainous districts of Ngoc Linh in Dak To (Kon Tum) and Nam Tra My (Quang Nam), so they are called Ngoc Linh Ginseng.
"This species of ginseng is considered extremely rare and is one of the 5 best ginseng varieties in the world.
"Ngoc Linh ginseng root is one of the ginsengs with the highest Sapoin content in the world, so their price ranges from 90-300 million VND/kg.($1=25,000 VND)"
Might this someday become a cash crop in the U.S.? Who knows.
