RHS repositions national plant collections as warming shifts what grows where in England

The Royal Horticultural Society is moving collections north — hydrangeas and rhododendrons to Greater Manchester and North Yorkshire — as heat stress damages them in southern England. Meanwhile, figs and almonds flourish at RHS gardens, and banana and lotus plants have flowered at Harlow Carr in Yorkshire, considered impossible a decade ago. The repositioning reflects shifting horticultural zones driven by climate change.
