General Information: Butterflyweed, also known as pleurisy root, locally found throughout the United States in high pH soils, is considered an introduced species in Kirby Park.  It generally occurs in dry fields or prairies in sandy soil, and flowers during the summer months.  This perennial is a member of the Milkweed family, however it is the only species without a milky juice.  The leaves of butterflyweed are alternately arranged with a narrow lance-shape.  The plant grows up to 2’ high with a hairy stem that is branched at the top.  The orange flowers occur in umbels.  It is planted to attract butterflies.
