Botany Certificate Classes

The NYBG Botany Certificate Program is designed to deepen a student's scientific understanding of the plant kingdom. Students engage in subjects such as native flora, ethnobotany, ecology, and botanical nomenclature. Courses reflect the Garden's strengths in botanical science research, as well as its world-famous and unequalled resources—the William and Lynda Steere Herbarium, housing some 7.4 million dried plant specimens, and the LuEsther T. Mertz Library, with its collection of more than one million cataloged items and 11 million archival documents.

During the course of the program, students will come to know plants: how they function, grow, develop, and reproduce; and learn to identify a wide array of plants by stems, leaves, flowers, and fruits.
