So have bluebells, wood anenomes, aubretia, cherry blossom, crab apple blossom, and even wisteria. In the first half of April! It'll end in tears; one sharp frost or sudden hailstorm and all the blossom will be lying in the gutter. I even saw a few flowers on a horse chestnut tree.
The roads round here are full of advertisments for the "Spring Garden and Leisure Show" at Ardingly showground over the May bank holiday weekend. At this rate they'll have to change it to the "Summer Garden and Leisure Show". Bet they'll have to use plastic daffodils; there aren't that many real yellow ones left.
