May in the Northern Hemisphere is early spring, and what a spectacular time of year for flowers! Global warming is causing slight shifts in seasons, making it difficult for the industry to say that such-and-such a bloom will most definitely be in season by early May. However, as a general rule of thumb, you can expect to choose from the following spring wedding flowers:
Tulips
Lilacs
Peonies
Irises
Rhododendrons
Azaleas
Hydrangeas
Bluebells
Roses
