Changing Climate Hampers UK's Wildflower Restoration Efforts
21 Aug
Summary
- Rising spring temps, unpredictable autumns make meadow restoration harder
- Certain species like primrose, cowslip vulnerable to climate change
- Need more research to understand climate change's impact on wildflower habitats

As the National Wildflower Centre (NWC) celebrates its 25th anniversary, it faces a growing challenge in its efforts to revive the UK's lost meadows. According to Juliet Rose, the head of development at the Eden Project where the NWC is based, rising temperatures in the spring and unpredictable autumns are making the task even more difficult.
The NWC has seen spring plantings fail or plants show signs of distress due to the hot springs experienced in 2025 and this year. Autumn has also become unreliable, with very wet periods making it hard to get seed in the ground. This has resulted in a "squeezed" growing window at both ends of the season.
Certain species like primrose, cowslip, and yellow rattle, which require cold periods to trigger germination, are particularly vulnerable to the impacts of climate change. The NWC has also heard from other growers about lower yields of perennial harvests this year due to the very hot spring.
Despite the sobering climate change warnings, the NWC remains optimistic. The center's key aim is to involve more people in restoration projects, with the simple act of sowing seeds seen as a way to connect with the community and one's ancestors. The NWC continues to work with individuals, communities, businesses, and organizations to establish wildflower-rich meadows across the UK.
