The China tea plant and the Assam tea plant are two varieties of a single species, Camellia sinensis, and every true tea in the world comes from one of them. The China type, Camellia sinensis var. sinensis, is a small-leaf bush that tolerates cold and gives lighter, more delicate teas. The Assam type, Camellia sinensis var. assamica, is a large-leaf, tree-like plant native to warmer country that runs richer and brisker in the cup and is sensitive to frost. They are not different plants, but different expressions of the same one, shaped by where they grew. Knowing which is in your cup is part of drinking with attention.
| China type (var. sinensis) | Assam type (var. assamica) | |
|---|---|---|
| Form | Small-leaf bush | Large-leaf tree |
| Climate | Cold-tolerant | Frost-sensitive, prefers warmth |
| In the cup | Lighter, more delicate | Richer, brisker, fuller |
| Native range | China | Yunnan through northern Myanmar to Assam |
One species, two paths
The two varieties diverged a long time ago in botanical terms, an estimated 0.38 to 1.54 million years back (Wei et al., PNAS, 2018), long before anyone thought to brew a leaf. Their shared home is Yunnan and the highlands of the wider region. The plant was first named Thea sinensis by Linnaeus in 1753, and settled into Camellia sinensis by 1881.
Why it matters to the drinker
The variety shapes body, briskness and how the tea holds heat and water. It is one of the reasons a delicate white and a full red tea can come from the same species and feel worlds apart. In Yangsheng Cha Dao, all of it is still tea, because all of it is Camellia sinensis.
Frequently asked questions
Are the China and Assam tea plants different species?
No. They are two varieties of one species, Camellia sinensis: var. sinensis (the China type) and var. assamica (the Assam type).
What is the difference between them?
The China type is a small-leaf, cold-tolerant bush giving lighter teas. The Assam type is a large-leaf, frost-sensitive tree giving richer, brisker teas.
Is Assam tea still Camellia sinensis?
Yes. Assam tea comes from Camellia sinensis var. assamica, a variety of the same species as the China plant, so it is true tea.
