I do not know about your area, but here spring typically means wind...with or without storms. The trees are covered in many tiny blooms and unfortunately the wind often sends them sailing to the ground long before they have even begun to brown.
As I walked my dog this morning I thought how sad to leave these lovely little blossoms to blow into the streets. I easily gathered handfuls of these Bradford Pear blossoms and displayed them in mini vases. I doubt they will last long, but with such little effort involved it was worth the joy they bring to my interior space.
