Unusually the violet helleborine is only pollinated by wasps and is thriving thanks to nectar that is irresistible to the insects
A rare orchid that reproduces by getting wasps drunk is thriving in the gardens of Charles Darwin’s house after a two-year restoration programme.
The violet helleborine is entirely pollinated by wasps, which are usually not perceived to be the best pollinators. They’re regimented and meticulously clean themselves, scientists say, which makes the process of pollination a fairly futile prospect – there’s nothing for the pollen to cling to.
