Snowdrops stand out because they are small and slender. These members of the Amaryllidaceae family are perennials that grow from bulbs and can be found throughout the United States and Europe. The bulbs of this lovely plant are poisonous, and must not be eaten. Snowdrops are characterized by small white blossoms that droop from the end of their slender green stalks. They are among the first flowers to bloom when spring comes and last through the summer. The small, white flowers of snowdrops provide a delicate counterpoint to the bolder and brighter colors that appear throughout the Conservatory Garden.
