In the summer, common milkweed is in bloom here. Female monarch butterflies will lay their eggs only on milkweed, the sole host plant for monarch caterpillars. In the fall, the adult monarchs migrate 1,900 miles from here to central Mexico, a feat of stamina and navigation unmatched in the insect world. The plentiful milkweed on the Phillips Farm has earned it formal recognition as a “Monarch Way Station” by the Monarch Watch Organization.
