Marigold
Any of a genus of herbaceous composite plants with showy yellow or red and yellow flower heads.
The second Marigold, a lighthouse tender built at Wyandotte, Wis., in 1891, was transferred to the U.S. Navy with the entire Lighthouse Service by Executive order 11 April 1917. The iron-hull tender operated on the Great Lakes as a naval vessel until 1 July 1919, when she was returned to the custody of the Commerce Department.
