Native Wildflower Postcard: Nodding Onion

In the 19th century, amateur naturalists preserved their botanical specimens in herbarium collections.  Pressed flat and carefully labeled, they served as aids in identifying different species and cultivars.  This card features Nodding Onion, a wildflower native to the Midwestern US and unusual among alliums for its drooping flower clusters.
 
Cards measure 4" x 6" and can be sent via the US postal service with a standard postcard stamp.
