The grounds include 60 acres of designed beds, specialty gardens, tree and shrub collections, lawns, and walking paths, and the adjoining 70-acre Frank G. Helyar Woods.
Around this time, a shrub display garden containing over 200 species and numerous varieties was established, which remains one of the oldest surviving sections of the existing collection (which was expanded between 1930 and 1950).
Some of the oldest hollies at Rutgers Gardens were planted in the late 1930s, and expanded through the 40s, 50s, and into the 60s, as part of an active breeding program.
In 1993, Dr. Bruce Hamilton, Rutgers professor, accepted responsibility for directing the Gardens' management and funding.
Still a self-supporting entity, the funds necessary for maintaining the gardens, purchasing equipment and materials, supporting salaries, and providing public programs are raised through facility rentals, special events, membership dues and donations.
