Here's another fabulous location from the Rensselaer County Garden Tour 2009, which is a fund-raiser for Cornell Cooperative Extension's Master Gardner Program.
This was not just a garden, but an detailed landscape. The description in the guide says this started out as a 5-acre mowed field. Of course, that was over 40 years ago, but I'm still jealous that I haven't gotten there yet with my own garden.
This garden featured lots and lots of containers (not necessarily the expensive decorative ones - many were plain plastic). These were mixed throughout the regular plantings. It looked great - I'll have to give that a try. There were also many of "antique shop" type ornaments - this is a very heavily accessorized garden!
