One of the most delightful signs of spring is the emergence of the lilacs.  Here in Minnesota lilacs are used as trees, shrubs, and even hedges.  They are in every neighborhood, with some bushes looking like they’ve been there for decades.   By the sides of the highways and roadways there are blocks of lilacs, all in full bloom with various shades of purples, pinks, and whites.  Even more exciting than the sight of lilacs is the wonderful scent that floats throughout the air at this time of year.  A fresh rain shower, a light breeze, and the air is alive with their floral scent.  I have cut some of our lilacs and brought them into the house to enjoy the scent.  Although the blooms don’t last long, I will not tire of replacing the spent blossoms to enjoy their fragrance for the brief few weeks that they grace our landscape.
