There is a sign that commemorates his boyhood home and burial in Saginaw, Michigan. The historical marker notes in part:
Theodore Roethke (1908–1963) wrote of his poetry: The greenhouse "is my symbol for the whole of life, a womb, a heaven-on-earth." Roethke drew inspiration from his childhood experiences of working in his family's Saginaw floral company. Beginning in 1941 with Open House, the distinguished poet and teacher published extensively, receiving a Pulitzer Prize for poetry and two National Book Awards among an array of honors. In 1959 Pennsylvania University awarded him the Bollingen Prize. Roethke taught at Michigan State College, (present-day Michigan State University) and at colleges in Pennsylvania and Vermont, before joining the faculty of the University of Washington at Seattle in 1947. Roethke died in Washington in 1963. His remains are interred in Saginaw's Oakwood Cemetery.[14]
The Friends of Theodore Roethke Foundation maintains his birthplace at 1805 Gratiot in Saginaw as a museum.
Roethke Auditorium (Kane Hall 130) at the University of Washington is named in his honor.
In 1995, the Seattle alley between Seventh and Eighth Avenues N.E. running from N.E. 45th Street to N.E. 47th Street was named Roethke Mews in his honor. It adjoins the Blue Moon Tavern, one of Roethke's haunts.[15]
In 2016, the Theodore Roethke Home museum announced their "quest to find as many as possible of the 1,000 hand-numbered copies of [...] Roethke's debut collection, Open House, to celebrate the 75th anniversary of the work's publication."[16]
