One of the country's rarest and most threatened wild plants has "astounded" conservationists by thriving on an industrial-estate nature reserve.
The field wormwood plants grow on one of the tiniest reserves in England in Brandon, Suffolk.
Botanists and volunteers of the group Plantlife said the number of flowering plants had rocketed from two in 2019, to 85 at the latest count.
Plantlife said traffic at the site kept hungry deer and rabbits away.
