Five plants that changed Britain's gardens

Many of our best-loved gardens are home to exotic plant collections from around the world.
Brought back to the UK by plant-hunters, these collections have enriched our landscapes and added flavour and colour to our menus.
In the spring edition of the National Trust Magazine, we tracked these early collectors across the world in search of their treasures. Among the exotic specimens brought to our shores, here are five plants that have changed Britain’s gardens and parks.
