arboretum plant sale

The annual Arboretum Auxiliary Plant Sale is fast approaching, and our volunteers and staff have been busy tending to plants in preparation for the big day. Hundreds of choices will be available to take home, whether it be stately trees, native shrubs, ornamental perennials, culinary herbs or something to help green-up the inside of your home.

Amongst the trees available this year, the producer of Canada’s largest native fruit, pawpaw (Asimina triloba), is an ever-popular choice. Durable and pest-tolerant shade trees that thrive in Guelph’s soil include chinquapin oak (Quercus muehlenbergii), basswood (Tilia americana) and blue ash (Fraxinus quadrangulata). And, beautiful specimens for the garden such as yellowwood (Cladrastis kentuckea), ginkgo (Ginkgo biloba) and Allegheny serviceberry (Amelanchier laevis) will also be available.

On the smaller side, the selection of shrubs include difficult-to-find native gems such as leatherwood (Dirca palustris) and buffaloberry (Shepherdia canadensis), southern standouts such as American beautyberry (Callicarpa americana) and bottlebrush buckeye (Aesculus parviflora), and edible fruit-bearing plants such as low juneberry (Amelanchier humilus), goji berry (Lycium barbarum) and black raspberry (Rubus occidentalis).

In total, over 100 taxa of woody plants will be available for sale, including 70 native to Ontario.

On the herbaceous side, there is a huge selection of classic garden favourites such as hosta, sedum, delphinium and iris, in addition to beautiful natives such as tall coreopsis (Coreopsis tripteris), Virginia mountain-mint (Pycnanthemum virginianum) and Culver’s root (Veronicastrum virginicum). Shade lovers include sharp-lobed hepatica (Hepatica acutiloba), maidenhair fern (Adiatum pedatum) and thimbleweed (Anemone cylindrica), while drought-tolerant plants include rattlesnake master (Eryngium yuccifolium) and pearly everlasting (Anaphalis margaritacea). Grass-like texture is provided by little bluestem (Schizachyrium scoparium), switchgrass (Panicum virgatum) and palm sedge (Carex muskingumensis), amongst many others. Showy and prolific bloomers include red-hot poker (Kniphofia 'Nancy's Red') and blue mistflower (Conoclinium coelestinum). Also, while some goldenrod species can be aggressive spreaders, others are much better behaved in the garden, and all are significantly supportive to local biodiversity ( Species available this year include early goldenrod (Solidago juncea), zigzag goldenrod (Solidago flexicaulis), white goldenrod (Solidago bicolor) stiff goldenrod (Solidago rigida) and upland white aster (Solidago ptarmicoides). And, remember, while goldenrods are often blamed for allergies while blooming in the autumn, they are actually insect-pollinated, and it is pollen drifts from the wind-pollinated ragweed that is the main culprit for sneezes!

In addition to the cold-hardy choices already mentioned, we`ll also be offering a selection of plants that are better suited for growing indoors over the winter months. These include elephant-ear kalanchoe (Kalanchoe beharensis), night-blooming orchid cactus (Epiphyllum oxypetallum), hedgehog sedum (Sinocrassula yunnanensis) and Cherimoya (Annona cherimola). Look for these and many other indoor plants on the day of the sale.

This year’s sale falls on Saturday, September 13th at The Arboretum’s RJ Hilton Centre, 384 College Avenue East. The event runs from 9 a.m. until 2 p.m., but be sure to arrive early for best selection, as some plants sell out quickly. Click here for a full listing of available plants. Please note that it is best printed in a landscape format.

Hope to see you there!

Arboretum Beginning

The Arboretum at the University of Guelph is somewhat modeled after the Arnold Arboretum of Harvard University which is 100 years older.

Plantings started in 1971 and are now maturing to produce a beautiful landscape, within which The Arboretum continues to develop specialized gardens, botanical collections, and gene conservation programs.

Labels are maintained at the base of all woody plants in the collections that are listed on The Arboretum map.
