Galanthus nivalis 

 After a long winter here in Minnesota we look forward to the first signs of spring.  A family tradition has been to attend the pancake breakfast at the Minnesota Landscape Arboretum.  While walking through the tapped maple trees the first Snowdrops of spring can always be found with their nodding white flowers emerging from the leaf litter.  Some years they will even be blooming through the snow.  Snowdrops signal the beginning of spring in Minnesota.
