This is the catalogue that goes with the exhibition in the LuEsther T. Mertz Library's Art Gallery at the New York Botanical Garden. Presented in partnership with the Oak Spring Garden Foundation it features masterworks of the botanical art collection belonging to the late Rachel Lambert ("Bunny") Mellon. Curated by Dr. Lucia Tongiorgi Tomasi, Susan Fraser, and Tony Willis, the exhibition comprises nearly 80 important works of art ranging from rare watercolours by renowned botanical artists such as Jacques Le Moyne de Morgues and Pierre-Joseph Redouté to 20th-century paintings by Pablo Picasso and Andy Warhol. This exhibition catalog provides a new perspective from which to appreciate Bunny Mellon's extensive collection and appreciation of botanical art.
