Dwarf Snapdragon – The Railroad Weed
Keyword(s):
Believed native to the Mediterranean region, dwarf snapdragon [Chaenorrhinum minus (L.) Lange ♯ CHNMI] was introduced into North America in the late 19th century. Since its introduction, it has spread, mainly along railroad lines, to at least 30 states as far west as Kansas and Nebraska. Increased use of herbicides by railroad companies has resulted in a marked decrease in its abundance in recent years.
