City of Montreal horticulturalist Jean-Pierre Duford was among the group on a hike who found the plant.

About a dozen people walked through the St Jacques Escarpment eco-territory in celebration of the city's move to save the area, as well as plans to build a pedestrian walkway over the Turcot Interchange.

Public consultations are starting on the park and pedestrian walkway over the Turcot Interchange.
