specialized gardens, botanical collections, and gene conservation
programs. Labels are maintained at the base of all woody plants

diversity in plants. It is a great place for weddings, dinner
theatre or memorial services and dedications. The Arboretum
offers Docent-led tours as well as naturalist / horticulturist-led
tours throughout the year. A wide array of adult and children's

the efforts of over 150 volunteer auxiliary members from
the City of Guelph, the University, and financial support
of hundreds of people, The Arboretum could not be what it
is today. The Arboretum is a significant visitor attraction
as well as an important amenity for the citizens of Guelph
Maples, oaks and beeches, serviceberries, crabapples, birches,
viburnums, dogwoods, lilacs, rhododendrons, and the conifers
(pines, spruces, firs, cedar, junipers and larches) are presented
as a more in-depth display of the genera. In these collections,
the emphasis is still on species diversity and includes a
range of cultivar selection. The map of The Arboretum will
orient you to the location of these detailed plant collections.
lilacs, serviceberry and dwarf conifers display the extent
of horticultural plant selection. The rose collection is significant
in that no insecticides or fungicides are used to sustain
any plants. This allows visitors to consider which roses would
manage well in a pesticide free landscape. The dwarf conifers
are presented in their natural form and growth rate and the
sculptural variation is quite stunning.
