Jeff Koons's monumental Split-Rocker from 2000 is an architectural scale living sculpture that merges the heads of two rocking horses — one a pony that once belonged to the artist's son and one a dinosaur — covered in over fifty thousand drought tolerant flowering plants. Standing thirty seven feet tall, the work is supported by an internal stainless steel armature with a built in irrigation system, allowing the vegetation to continuously grow and evolve, attracting birds and butterflies over time. Rooted in Koons's lifelong fascination with childhood memory, fantasy architecture, and the elevation of playful forms to monumental status, the work invites viewers to reflect on wonder, personal associations, and the boundary between nature and sculpture. A gift to the museum from Lynda and Stewart Resnick, this piece exemplifies Koons's signature ability to transform familiar cultural imagery into ambitious, thought provoking public art.
