Purple Cone Flower (Rudbeckia hirta)

Purple Cone-Flower (Rudbeckia hirta)

This pretty weed has been brought to the East in clover-seed from Western fields. It grows 1 to 2 feet high, and colors whole fields with bright yellow, possessing strong roots and an aggressive nature, so that, once established, it is difficult to eradicate. New Jersey farmers regard the cone-flowers with disapproval, but city boarders love them, especially mixed with white daisies, and fill large jardinieres with the golden blooms.
