The Dalhousie Agricultural Campus and its Bicentennial Botanical Garden is the Faculty of Agriculture鈥檚 largest classroom.

Horticulture and wood construction students play a large role in contributing to the garden and its many spectacular features including the Rock Garden which recently received the Frank Cabot Public Garden Award during the North American Rock Garden Society (NARGS) annual conference held on the Truro campus last month.

Established in 2018, this award is given to a public garden that excels in furthering the purpose of the North American Rock Garden Society in promoting the construction and design of rock gardens; the cultivation, conservation, and knowledge of rock garden plants and their geographical distribution; and the public outreach through plant exploration and introduction of new garden-worthy species.

The Truro Rock Garden is one of the two largest rock gardens in Atlantic Canada and is one of the most significant horticultural features in Eastern Canada.

鈥淲e were so pleased and honoured to be the recipient of such a prestigious award from the North American Rock Garden Society,鈥� said Dean David Gray. 鈥淚t speaks to the talents and vision of our faculty and staff while making a significant contribution to our campus community and community at large.鈥�

The grounds of the Dalhousie Agricultural Campus encompass 26 acres and contain several horticultural features including a pollinator garden, rock wall, Alumni Gardens, herb garden, heath and heather garden, a substantial rhododendron display and a spectacular rock garden.

The Rock Garden鈥檚 initial construction began in 2002 and was designed by Dr. Bernard Jackson, retired director, and designer of the Memorial University of Newfoundland Botanical Garden.聽 Much of its upkeep is maintained by a large group of volunteers known as Friends of the Garden.

鈥淢any years of hard work and dedication has gone into the creation of the Rock Garden by Dr. Bernard Jackson, the Friends of the Garden, and the Botanical Garden Unit,鈥� explained Chelsea Baird, Outdoor Classroom and Landscape Manager. 聽鈥淲e are very grateful to receive this award which acknowledges the true essence of what our Rock Garden embodies,鈥� she added.聽 鈥淲hile it plays host as a beautiful backdrop to many monumental pictures in many people鈥檚 lives within the community, it most importantly serves as a valuable, living, educational resource for our students and visitors to experience many rare and special alpine plants and the art of rock gardening. We are proud to be able to share our gardens for all to learn and enjoy.鈥�

The Rock Garden covers just over one-half acre of land and is situated on a south facing slope. It consists of a rock face, two dry streams, a gravel scree bed, peat bed and woodland garden. The rock face area is quite hot, featuring sun-loving and drought-tolerant alpines along with a significant collection of hardy succulents.

The dry streams are in two gullies, designed to look like old, rock-lined erosion gullies.聽 These gullies provide a damp area for specialized alpines but also has a practical function in funnelling and carrying away, any excess rainwater from the Garden. The scree houses tap-rooted plants that require exceptional drainage. Scattered throughout the Garden is an impressive collection of dwarf shrubs and conifers. The peat garden features Ericaceous plants and other acid-loving plants. The woodland section is a transitional area between the newer Courtyard Trough Garden and the rest of the Rock Garden and is comprised of small to mid-sized deciduous trees and conifers that provide habitat for shade loving woodland plants.

鈥淭he Rock Garden within the Bicentennial Garden is one of the most significant horticultural features in all of Atlantic Canada and is a must-see destination for any visiting plant-lovers,鈥� said Todd Boland, vice president of NARGS and horticulturist at the Memorial University Botanical Garden. 聽鈥淭he Francis Cabot award bestowed by the North American Rock Garden Society is well deserved!鈥�

The original Rock Garden contains 800 tons of local red granite and features impressive stone steps that help traverse the undulating nature of the Rock Garden.聽 The Garden also features two cedar bridges constructed by students in their wood construction techniques class.

Directly east of the original Rock Garden and woodland garden lies the impressive Courtyard Trough Garden. The trough area was built in 2003 with grant support from the Norman Singer Endowment Fund provided by the North American Rock Garden Society. The physical construction of the courtyard was started as a class project with third-year horticulture students in landscape project management. The area features natural stone walls, a limestone courtyard, crevice gardens and hand-cut natural sandstone alpine troughs.

The courtyard area is popular with local photographers as a backdrop for weddings and graduations. The east entrance to the courtyard is framed by an eastern white cedar shingled arbour structure which was also constructed by students.聽 Local rock garden enthusiasts were anxious to help with the courtyard and other aspects of the Rock Garden and through Bernard Jackson鈥檚 encouragement, the Nova Scotia Rock Garden Club was started, soon becoming a chapter of NARGS.

In 2018 there was an extensive expansion made to the Rock Garden. Utilizing 450 tons of limestone, a new rock garden was constructed containing low cliffs, talus slope and scree, a crevice garden, limestone pavement garden and an outdoor classroom.聽 To finish off this new expansion, students from the landscape project management class constructed a man-made pond and bio swales to control water runoff from the nearby parking lot. In 2019 an alpine meadow was added.

In addition to receiving the Frank Cabot Public Garden award, the NARGS Executive awarded $5000 for the purchase of additional rock garden plants from Wrightman Alpines Nursery.

鈥淭his demonstrates the appreciation that all members have for the important work of the university staff, students and volunteers in maintaining the Garden,鈥� added Jim Sharpe, NARGS 23 Co-Chairperson.

The campus gardens are open to the public at any time.聽 Learn more about the Bicentennial Botanical Garden at dal.ca/gardens
