The Arboretum Plant Sale is one of our largest fundraisers of the year and an important part of continued Arboretum development. All proceeds from the sale of plants go towards maintaining our 165 hectares of plant collections, gardens, natural areas, conservation programs, research projects and educational opportunities. The grounds are open to the public free of charge, year-round, from dawn to dusk. The Plants Plants are grown in The Arboretum’s nursery by Arboretum staff and a very dedicated crew of Arboretum volunteers. Many of the individual plants offered for sale are extras from the development of our plant collections at The Arboretum, while other special plants are grown specifically for the sale. These plants represent some of the best choices for gardens in our area as displayed in many parts of The Arboretum, where our formal woody plant collections now total over 1850 types of trees and shrubs, in addition to countless herbaceous plants growing in our gardens and natural areas. This year, we once again offer you some of our favourites at the 2015 Arboretum Auxiliary Plant Sale.

Plant Sources Originally, all plants were donated to our plant sale by volunteers and other interested individuals. It soon became apparent, however, that we were unable to produce the number of plants needed for our purpose. Seed sources have now expanded in many interesting directions to meet the increasing demand. 1. Seed from Local Gardens – Several volunteers supply seed from their own gardens. This provides plants of known hardiness and cultivation requirements. 2. Native Plants – All wild seed is collected under the guidance of Arboretum staff members. Seed is collected responsibly in order to maintain wild populations. We do not strip local woodland areas of desirable plants. If we can’t offer them in an ecologically-responsible manner, we don’t offer them at all. We have occasionally salvaged plants from areas about to be developed. The reasons for the strong emphasis on native Ontario plants are ecological and educational – they fit the local climatic zone and they are often more tolerant of local pests. Many are under pressure from expanding urbanization and bringing them into gardens is one way of preserving them and making people more aware of this important and beautiful part of our heritage. 3. Non-native Plants – In 1996, we began ordering seed from various seed houses and societal seed exchanges. This, coupled with seed gathered from some of our own Arboretum plant collections, allows us to offer an incredible selection of plants at our sale.

Again this year, we plan to offer some specially-marked “Gold Star” plants. These are particular favourites of Arboretum staff members that are often exceedingly rare or unusual. We’re also expanding our selection of edible plant species for those looking to begin growing their own food at home. Look for these on the day of the sale, and take home something special!

Special Instructions The following plant list is organized into two sections; Woody Plants (Trees, Shrubs & Vines) and Herbaceous Plants (Perennials). Plants native to Ontario, those that have edible parts and those that are of limited quantity are noted. While a great deal of effort has been taken to ensure accuracy with this plant list, some of the plants offered for sale may not grow exactly true to the names for the following reasons:  Some of the plants have been donated. In some cases the donors may not always know the exact species, variety and cultivar of the plants they donate.  Most of the plants have been grown from seed, some of which will have been open-pollinated. All of the plants offered, except those on the special “Indoor Plant” table are cold-hardy to Guelph and areas of equal or exceedingly warmer plant hardiness zones. The majority of the plants available prove to be much hardier still, often growing well north of the Guelph area. Cold hardiness can often be extended in many plants by offering winter protection in the first several years after transplanting, as well as selecting an appropriate site with limited exposure to desiccating winter winds and late spring frosts.

On the day of the sale, please be sure to take advantage of our ‘ASK A MASTER GARDENER’ to answer questions in the line-up or in the sale area. And, as always, Arboretum staff and auxiliary members will also be readily available to assist with all inquiries.
