This herb has been in use in the conventional Chinese medicine for more than 2000 years. It is a perennial plant that usually growing in abundance in China, Japan and Korea. Usually the plant grows up to a height of about 1.5 meters. While the plant blossoms all through May and June and the seeds mature around the month of September. The flowers of asparagus are dioecious meaning they have only one sex - male or female. Moreover, each plant of the species can bear only either male or female flowers, rendering them incapable of self fertilization. Thus, in order to produce seeds, both male and female Asparagus cochinchinensis need to be grown near each other so that bees are able to pollinate the flowers.
