Green teas are perfect however from those plants which are grown at a height of 3000-6000 feet, because in such climatic conditions the leaves will grow slowly along with slow maturation of plant and will yield the best flavored taste. Based on the altitude on which this plant has grown, it will take an average 2 to 5 years to get ready for leaves picking and when it starts bearing its leaves, it will remain productive for up to a century.
