I dont know anyone personaly but it seems to sprought easily from small pieces left over after choping . I have used the waste after choping washing ect. in my ginseng beds and now they are covered with cohosh so I think it would be easy to cultivate dont know if theres money to be made their though.
It did have some buds but i think even small cutlins will sprout and grow a new plant in fact when i havest wild cohose i like to cut off a small piece and put back in the hole to grow a new plant.
