Kew Gardens, a UNESCO World Heritage site, has evolved from a 9-acre area in 1759 to over 300 acres, showcasing the largest living plant collection in the world while actively participating in global conservation efforts. The Millennium Seed Bank at Wakehurst plays a crucial role in preserving endangered plant species, having banked over 13% of the world's wild plants in collaboration with partners across 80 countries. Innovations in technology, such as iBeacon and Bluetooth LE, are being tested to enhance visitor experiences and increase awareness of Kew's scientific and horticultural significance.
