Auxiliary memberships are available to existing Arboretum volunteers only. Visit for step-by-step instructions on becoming an Arboretum volunteer.

A limited number of high quality bulbs from the Netherlands in the same colors that will be planted at the Arb next spring will be sold in packets with a minimum of 6 bulbs for $9.

Private Garden Tours 2022


The Auxiliary Private Garden Tours feature beautiful gardens, each with its own history and distinct beauty. Guests travel in air-conditioned motor coaches and tours are followed by a brunch, luncheon or hors d'oeuvres, depending on the day and time of the tour. To ensure our guests have a memorable experience, volunteers help as bus escorts and garden hosts. All proceeds go to support the work of the Arboretum.
