Nancy Blum’s large-scale glass mosaic botanical murals grace the platform walls of the historic 28 St station. The artwork celebrates the flowering plants that can be found in nearby Madison Square Park Conservancy’s Perennial Collection. The seven blooming plants depicted were chosen as representative of plant species that withstand changing climate conditions of the city, and include: Red Buds, Magnolias, Hellebores, Witch Hazel, Daffodils, Hydrangea, and Camellia.   

Known for her beautiful floral studies that reveal astonishing detail, Blum transforms the study of botany into bold and expressive statements of art, which were translated into glass mosaics by Miotto Mosaic Art Studios for the station. Similar to an ever-changing garden, "ROAMING UNDERFOOT" creates a delightful place to enjoy nature during every season. Blum’s intent was to capture some of the magic of the nearby park, regarded as an urban sanctuary, and to enhance the station environment for transit riders.  

Nancy Blum is a Brooklyn-based artist whose large‐scale works on paper, rendered in ink, colored pencil, gouache, and graphite, portray a fantastic realm in which flowers own the space. Blum uses a variety of 16th- and 17th-century botanical images, from Chinese plum blossoms to German botanicals, as starting points for each drawing. She received her MFA from the Cranbrook Academy of Art and has since become a widely sought-after visiting artist, critic, and lecturer at universities nationwide.
