Blooming season

Wordsworth's famous daffodils hold clues to the future of climate change.

Predicting what tomorrow will bring is a bit of a dark art. With no crystal ball or time machine, how can you look into the future? Well, I鈥檝e already discovered how the countryside holds clues as to what鈥檚 happened. But can it also hold clues as to what鈥檚 going to happen? Time to head to the Lake District. This is Ullswater, and is surrounded by powerful scenery. The scenery is evidence of the last dramatic climate change, the last ice age, when these Fells were exposed and the lakes scoured out and Britain was more like the Arctic. But the lakes also have clues of more recent climate changes, changes which are happening today. The evidence for them is just over there. These bashful flowers have a secret to tell, and they鈥檙e no ordinary daffodils. For a start they鈥檙e our wild native daffodil, also known as the lent lilly. A wonderful delicate flower, much more elegant than those big fat garden hybrids. And these particular daffs are also the most famous in the world. They provided inspiration for one of our greatest poets. 鈥業 wandered lonely as a cloud that floats on high o鈥檈r vales and hills. When all at once I saw a crowd, a host of golden daffodils鈥�. It was these daffodils beside this very lake that were 鈥榝luttering and dancing in the breeze鈥� when William Wordsworth stumbled upon them. But what鈥檚 really important is when Wordsworth found these flowers. And we know that to the day, thanks to his sister鈥檚 diary. On April 15th 1802, Dorothy Wordsworth wrote 鈥榳hen we were in the woods beyond Gowbarrow Park we saw a few daffodils close to the waterside, we fancied that the lake had floated the seeds ashore鈥�. While the Wordsworth鈥檚 were here in the middle of April, 200 years on, this is in the middle of March. These daffs are flowering one month earlier, and they鈥檙e not alone. Many of our spring flowers are springing up early, and it鈥檚 a hint of what the future might hold. You can see it happening in your own backyard. Everything just seems to flower sooner than it did when Alan first started gardening. Even our woodland bluebells are ringing the changes. When I was a kid, they always flowered for my birthday in early May. But these days its Mid to late April, when this azure carpet rolls out over the forest floor. In fact, 200 species of wild flower, are blooming two weeks earlier than they were in the 1950鈥檚. But this trend isn鈥檛 just restricted to flowers, other spring events are happening earlier too. As the season shifts forwards, trees are also bursting into life ahead of schedule. And its not just spring that鈥檚 on the move. At the other end of the year, Keat鈥檚 season of 鈥榤ists and mellow fruitfulness鈥�, Autumn, seems to be arriving later. When I was growing up I spent many an autumn day raking up leaves to stuff my home made Guy Fawkes, in preparation for November 5th. But these days kids have to use newspaper. Because even on bonfire night, most leaves are still on the trees.
