A Fascinating History of Discovery
Our Timeline: 1893-1965

Borde Hill estate sold to Stephenson Robert Clarke (Stephie)
A Mrs Cunliffe Lister sells the Borde Hill estate to Stephenson Robert Clarke (1862-1948). Heir to the Stephenson Clarke shipping firm, he bought Borde Hill with the sole intention of creating a great garden. The Colonel began collecting plants soon after he acquired the Estate.
When he bought Borde Hill it only had 8 acres of land. Over the next fifty years he increased his land holding to 21,000 acres, creating the formal plantings in the Garden, and planting extensively in selected woodlands around the estate where their microclimates were especially suitable for more tropical flora and fauna.
