Tregothnan Tea is an English tea, actually grown in England.
It is grown at Tregothnan estate owned by the Boscawen family near Truro, Cornwall.
The estate has a plantation of about 8,000 tea bushes (as of 2006) of the Camellia sinensis variety of tea.
Harvesting of the leaves starts when the bushes are about 3 feet (1 metre) tall.
The estate produces both black and green tea in small quantities.
The tea is expensive: the price per 3 oz (100g) is £9 for a blend of Tregothnan and Assam tea, £12 for green tea and £22 for what the estate calls “New Darjeeling” (2006 prices.)
