  4. Landscape & horticulture - in building the museum, the first public institution on the newly constructed back bay fens, isabella stewart gardner contributed to a conception of the city as shaped by landscape architecture. The museum remains committed to being a preeminent cultural venue for landscape and its role in the contemporary city. The landscape department curates exhibitions and convenes public programs on topics of societal, environmental, and cultural significance for contemporary boston. These programs present our audiences with the most pressing challenges of the day, as well as the role of design and planning in addressing those challenges. The museum maintains a varied living plant collection, with many species descending from the founder's own era. Additionally, the horticulture department propagates thousands of plants each year for seasonal displays in its iconic courtyard. The monk's garden, horticulture workshops, and other programming further bring the art of horticulture to life as part of the museum experience.

  5. Contemporary art - the artist-in-residence program is one of the oldest in the country, beginning in the early days of the museum when gardner's friend john singer sargent stayed in an apartment on the ground floor. Since 1992 the museum has invited artists from all creative disciplines and backgrounds to once again stay on the premises to research, work and respond to the collection, offering fresh perspectives on gardner's creation. These artists often return multiple times to find inspiration, to enjoy the gift of time and to stay connected to the museum in meaningful ways. Thanks to the new strategic plan, the contemporary department has continued to forge dynamic new connections between museum audiences, living artists and the collection, while expanding the focus on specific thematic exhibition projects and commissions, which connect gardner's total work of art to relevant issues of contemporary culture.
