A lifelike Banyan tree recalls the tropical rainforest
at the National Museum of Natural History.
Orchids
of Latin America (Natural History, January 26-April 21, 2013) explored
the crossroads of botany, horticulture, and culture. Exhibit planners wanted to
transport visitors to the tropical rainforest, so they requested a dramatic Banyan
tree sculpture at the exhibit entrance to evoke the orchids' lush habitat. Orchids has since closed, but the tree
remains at NMNH.
Designing, making, and installing a life-sized
tropical tree required careful planning by OEC’s Model Shop. The tree was made
in sections to allow for transport and delivery through the hallways at NMNH.
Modelmakers began by building
a welded armature trunk with removable branches. They then applied fire-rated urethane
foam and carved it into shape. Next, trunk and branches were coated with a
water-based, pliable material that would hold a texture and harden. Modelmakers
sculpted strangler fig vines on top of the trunk, and stained both with color. The
entire structure was transported to NMNH, where modelmakers attached branches,
adjusted leaves, and painted the surface to make the Banyan tree appear a
seamless whole.
