Great fall sale going on now. From 25 to 40 percent off perenials you would actually want in your garden. Worth the drive. Great prices especially for those of us used to Toronto and surrounding suburbs pricing.

I love it here. I want to buy everything when I go 😂. The staff are very friendly and there are so many beautiful flowers to choose from (and fruits, and veggies, and trees, succulents etc). I always come here first when I need a plant!

I've enjoyed their advice, plant selection and great prices. As if that wasn't enough this pandemic year they gave away free 33,000 lilies to local families and our church. Thank you!
