Rhubarb Triangle
The Rhubarb Triangle is a 9-square-mile (23 km2) triangle in West Yorkshire, England between Wakefield, Morley and Rothwell famous for producing early forced rhubarb. It includes Kirkhamgate, East Ardsley, Stanley, Lofthouse and Carlton. The Rhubarb Triangle was originally much bigger, covering an area between Leeds, Bradford and Wakefield. From the first decade of the 20th century to 1939 the rhubarb industry expanded and at its peak covered an area of about 30 square miles (78 km2).

That sounds wild! I can't imagine it! LOL even with pictures. It grows so abundantly and lush here! It even manages to survive and thrive through our winters. Nice of you to share this unique aspect to your community @dune69 🍓
