Gerardia

Gerardia purpurea is a member of the snapdragon family as you can see by looking at the flowers. It blooms in the fall and added to the colors of goldenrod, asters, and ageratum it is beautiful. It is also called purple false foxglove, or just false foxglove. It is parasitic on the roots of grasses, but judging from the roadsides, I would say it does not hurt the grass much. Each flower is about an inch wide. Once I tried to cut some for a vase, but they wilted right away.
