Camellia sinensis assamica
C tier
Camellia sinensis var. assamica is the large-leaf Assam type of tea plant, native to the humid lowlands and foothills of northeastern India, Myanmar, and southwestern China. Broad, soft leaves suit warm, wet climates and high biomass production; many Assam, Yunnan, and tropical plantation blacks and dark teas rely on assamica or assamica-hybrid genetics. The variety tolerates heat and monsoon conditions better than cooler-adapted small-leaf China types. Liquors tend toward full body, malt, cocoa, spice, and deep colour when fully oxidised, making assamica the workhorse of breakfast blends, CTC (crush-tear-curl) manufacture, and many pu-erh and Yunnan reds. Specialty whole-leaf lots can still show floral or fruity nuance, but market identity is strength, colour, and milk-friendly body rather than ultra-delicate green-tea delicacy.
Also known as: Assam large-leaf, Daye (large-leaf) populations, Estate assamica hybrids, African plantation assamica

History
Robert Bruce and local knowledge identified wild large-leaf tea in Assam, challenging reliance on Chinese plant stock alone.
Commercial Assam Company plantings began systematic estate production of Camellia sinensis assamica for export black tea.
Assam-type gardens expanded across the Brahmaputra valley, establishing industrial-scale black tea for British markets.
Assamica and hybrid stock underpinned much of Ceylon’s low- and mid-country black tea estate production.
CTC manufacture leveraged robust assamica leaf for strong, quick-colouring teas used in bags and blends.
Yunnan large-leaf populations (assamica and related) gained global specialty status for sheng and shou pu-erh.
