On the weekend I found myself at a loss trying to find unique Hostas. So I finally googled ottawa garden centers and found the Rideau Woodland Ramble. They have 100 different varieties of Hostas. It's a great place to not only purchase perennials for their garden but also to see them growing. There's a collection of paths that take you through the woods and along a pond. It's a beautiful experience even if you aren't looking for plants. http://www.rideauwoodlandramble.com
