This is probably the best garden centre on the island of Montreal. You can find just about everything here, from mid-sized magnolia trees, Japanese maples and other trees should you have a bit of property to play around with to tiny little pots of herbs and flowers for your urban balcony garden and literally everything in between. Wind-chimes, cactuses, berry bushes, hanging plants and planters, the list could go on forever.
Try to go early in the morning because practically every gardener in Montreal is hanging out here, get a car, stock up on your plants and potting soil and you're good to go for the summer. This place has by far the best and widest selection but not necessarily the best prices as they have been steadily going up here I've noticed in recent years. Canadian Tire has the best prices still for herbs and small plants but if you're looking for that rare herb or a bush of golden raspberries to grow wild in the corner of your yard, then come here.
