Trewidden Garden is a 15-acre subtropical garden near Penzance, notable for its rare collection of camellias and magnolias. Established in the 19th century, the site features a former open-cast tin mine, now landscaped into a sheltered valley environment. The garden maintains a collection of Australian Tree Ferns, specifically Dicksonia antarctica, which thrive in the mild Cornish microclimate. Visitors follow a network of paths through wooded areas and open spaces containing over 300 different camellia varieties. The estate includes a tea room serving locally sourced refreshments and a nursery offering propagation from the garden's own plants. The garden serves as a significant botanical site in West Cornwall, benefiting from the frost-free conditions of the Penwith peninsula.
