It's rare to see a blue flower -- let alone a whole field of them. But that's the main attraction at Hitachi Seaside Park's annual spring event, Flowering. The nemophila, also known as baby blue eyes or California blue bells, reach their peak sometime between mid-April and early May. The park website has updates on the blossom progression as well as peak bloom times from previous years to help you plan when to go. While the nemophila steal the show, there are also daffodils (the first to bloom, from late March to mid-April) and tulips (from mid- to late April). Looking for more spring bloom ideas?
