How plant hunters sowed the seeds of garden invaders
Plant hunters introduced many of the UK’s most damaging invasive species as botanical status symbols in the Victorian era. Initially, the impact of plant hunting for sought-after specimens, such as camellia and rhododendrons, was largely unknown. However, without natural predators from their home range, these plants grew uncontrollably in British gardens and spread into the…
