Reiman Gardens is situated on a 14- acre site located immediately south of Jack Trice Stadium on the Iowa State University (ISU) campus in Ames, Iowa. Reiman Gardens (pronounced Rye-Men) is a year-round facility that has become one of the top ten attractions in Central Iowa. It is open seven days per week, from 9:00 am to 4:30 pm, with extended hours in the summer season and extended evening hours for its annual events. The Gardens are closed on Thanksgiving, Christmas, and New Year's Day.
Reiman Gardens consists of a dozen distinct garden areas, an indoor conservatory and an indoor butterfly "wing", butterfly emergence cases, a gift shop, and several supporting greenhouses. ISU students and their classes are admitted free of charge, as are the Gardens' members, known as CoHorts. An admission fee is charged to the public. Many United Way of Story County agencies directors can receive free passes to distribute to their clients.
Iowa State University has had a horticulture garden since 1914; Reiman Gardens is the third location for these gardens. Today's gardens began in 1993 with a gift from Bobbi and Roy Reiman. Construction began in 1994 and the Gardens' initial 5 acres (20,000 m2) were officially dedicated on September 16, 1995. The landscape design was created by Rodney Robinson Landscape Architects. The Mahlstede Horticulture Learning Center was the original building in the Gardens; the original maintenance building was torn down when the new conservatory was built and a new maintenance building was built in the an area of the S1 parking lot. The Gardens officially opened its 30,000-square-foot (2,800 m2) conservatory complex on November 3, 2002. The new building made the Gardens a year-round facility with an indoor plant conservatory (5,000 square feet), a glass house filled with tropical plants and exotic butterflies (2,500 square feet), an auditorium for classes and events, gift shop, an events hallway, greenhouses dedicated to the indoor glass house needs, a headhouse, staff offices, and two large areas housing all the heating and cooling and greenhouse systems equipment.
Architects Smith Metzger designed the Christina Reiman Butterfly Wing, the Mahlestede Learning Center, Conservatory Complex and Hunziker Garden House.
Annual themes 
Reiman Gardens uses a process called Dimensional Design to create its annual theme. Using a holistic approach, Dimensional Design requires a team effort from all departments. Thus, the Gardens' staff develops educational programs, interpretation, communications, events and amenities that support one theme, which in turn, also supports the Gardens' mission.
The theme encourages guests to view the garden and its mission from a different perspective each time they visit. By working annually, all displays have interconnected sub-themes that support the annual theme
What is the planning time-line?
- Theme year planning is done three to five years in advance.
- Conceptual planning (creating sub-themes) is started started two years in advance.
- Detailed design are prepared one year in advance.
Why Plan this Way?
- Gives structure to displays and programs
- Keeps displays and programs focused
- Generates innovative ideas
- Encourages repeat visits with something new to see every year
- Creates great sponsorship opportunities
- Strengthens the staff into a team
