Tregothnan - Cornwall - United Kingdom

The largest private botanic garden in the UK


The Estate owns substantial lands in Cornwall and Kent with farms, houses, commercial premises and woodland. Tregothnan has the largest, private botanic garden in the UK protecting some of the world’s rarest plant species. Tregothnan has been a pioneer of foreign farming in Britain for centuries, experimenting with the tea genus in its unique microclimate. In 2005 Tregothnan sold the first-ever tea grown in the UK. A diversity of lands allows Tregothnan to produce Cornish Manuka and wildflower honeys, rare Kea Plum Jam and coppiced charcoal. British flowers from Tregothnan and surrounding lands are made into hand-tied seasonal English bouquets.

Tregothnan’s Wild Escapes cottages are nestled in tranquil countryside, surrounded by the river Fal.


History of Tregothan

The Boscawen family have lived at Tregothnan since 1334 and is the seat of the Viscount Falmouth.

The name ‘Tregothnan’ literally means ‘The House at the Head of the Valley’ and is still a private family home today. Admiral Boscawen commanded HMS Namur, a 90-gun battleship, during the Siege of Louisbourg in 1758 and won the battle of Lagos in 1759.

Tregothnan has the oldest ornamental Camellia bushes in the UK. At nearly 300 years old, the gigantic Camellias were the first to grow outside in the UK and Tregothnan is now home to National Collections of Camellias.

The oldest surviving part of the Estate is the iconic Kitchen Garden door which dates back to the Plantagenet era. Behind the door you will find one of Tregothnan’s thriving tea plantations, protected by the high walls of the Kitchen Garden.

Tregothnan introduced the Manuka plant from New Zealand in the 1800s and remains the only commercial grower of Manuka and producer of Manuka Honey outside of New Zealand.



Honourable EAH Boscawen inherited the estate from his father, the 9th Viscount Falmouth in 1985. He is also chairman of Goonvean Holdings Limited, a diverse industrial group. He lives at Tregothnan with his family.
