NJBG's Annual End-of-Winter Tree Walk. NJBG will sponsor an End-of-Winter Tree Walk at the New Jersey State Botanical Garden on Sunday, March 23, at 1 pm. Though it's still chilly outside, the signs of spring are already visible in many places if you know where to look! Join Head Landscape Designer Rich Flynn for a delightful educational walk in the Botanical Garden. You'll meet dozens of beautiful trees and learn how to identify them from their structure, branching, and budding patterns before the leaves once again appear. You'll enjoy the subtle signs of spring peeking out everywhere - a sure cure for cabin fever after a long hard winter. Meet at the Carriage House Visitor Center at 1 pm, and wear comfortable shoes. Snow or heavy rain cancels. The Tree Walk is open to the public free of charge, but a $5 donation is welcomed. The New Jersey State Botanical Garden at Skylands, which appears on both the State and National Registers of Historic Places, is open from 8 am to 8 pm every day of the year. Admission to the Botanical Garden is always free. In the spring, parking is also free. In 1966, the State of New Jersey purchased the 1,117 acres of Skylands, a former country estate and the state's first acquisition under the "Green Acres" preservation program. Governor Thomas Kean designated the central 96 acres surrounding the manor house as the State's official botanical garden in 1984.
