The annual Arboretum Plant Sale has been run by a group of dedicated Volunteer Auxiliary members since 1995. Word spread quickly about the quality of the sale, and in 2006 over 1,000 people came from far and wide to buy the more than 6,000 woody and herbaceous plants offered for sale. Proceeds from the sales have been used to upgrade Arboretum nursery facilities (streamlining of plant production; refurbishing of the Lathe House and the Shade House; purchase of a polyhouse), to build up The Arboretum's Endowment fund, and to help fund the Italian Garden.

Originally, all plants were donated by volunteers and other interested individuals. It soon became apparent, however, that this was unable to produce the number of plants needed. Seed sources have now expanded in many interesting directions to meet the increased demand, such as seed exchanges with organizations from around the world, wild seed collected in an ecologically responsible manner, surplus material from The Arboretum's own nursery, and seed collected by volunteers from their gardens.

The Plant Sale group welcomes new members throughout the year. If interested, please speak to Barb, our Volunteer Co-ordinator, at the sale, send her an e-mail  or call her at 519-824-4120 x52358.
