I know right? I love sitting on the deck and seeing that hydrangea!

Vanita we got our supplies from Floor and Decor and they helped us select the outdoors mortar that we needed not only for outdoor use but also we needed one appropriate for the wall so the tiles would not come crashing down on the wall part of our slate tiling. You can ask your local DIY store to help you out but make sure and tell them what kind of tile you are using, that is is outdoor and if you are doing a wall that your tile will be up on a wall so they can direct you to the proper mortar and grout to use.
