Latin name for tea plant is Camelia Sinensis (Camelia family).
In general, tea plant grows in tropical zone at 200-2000 meter altitude. The air temperature must be between 14 and 25 centigrade. The plant can be as high as 9 meters (Chinese and Javanese tea), but some can reach 12 to 20 meters (Assamica tea). Current record shows that there are some 1,500 tea variants from 25 countries in the world.
To ease tea leave picking, plant tallness shall be controlled by continuous cutting so that it is never more than 1 meter in height. With such height, picking good young leaves becomes a lot easier.
