Global heating: ancient plants set to reproduce in UK after 60m years
Two cycads (Cycas revoluta), a type of primitive tree that dominated the planet 280m years ago, have produced cones on the sheltered undercliffs of Ventnor Botanic Garden on the Isle of Wight.
The species is native to Japan and usually only found indoors as an ornamental plant in Britain, but one of the garden’s plants has produced what is believed to be the first outdoor female cone on record in the UK.

“For the first time in 60m years in the UK we’ve got a male cone and a female cone at the same time,” said Chris Kidd, the curator of Ventnor Botanic Gardens. “It is a strong indicator of climate change being shown, not from empirical evidence from the scientists but by plants.”
According to Kidd, last summer’s heatwave and this year’s record-breaking temperatures have “absolutely” caused the plant’s production of cones, with a run of milder winters also helping.
“The plant will have made the decision to commit to cone production [in summer 2018], and that production is set in place to run through over winter and produce the following year,” he said. “Thirty years ago we couldn’t have grown them. But these plants have been growing out of doors here in the gardens for 15 years, going through their natural cycles.”

“We see the undercliff here as being a predictor for the wider British landscape in 20 to 30 years time.”
