I found this nursery when we were travelling to Evansville, Indiana and needed a stop over on the way home. This was a commercial business with display gardens overflowing with art. In fall 2018 they closed down nursery operations and simply have the 8 acre forested garden area available. I do not know the hours of operation, but you may find what you need on their Facebook page.
When we went to visit in 2014 after our quest to Evansville, Indiana to see an LST (Landing Ship Tank - a troop and equipment transport from WWII) we stopped by because it was open on a Sunday when many other things were not. The garden art is worth trekking the back roads of Utica Indiana to find it.
The promotional shot for the place has this man made out of salvaged metal parts, but the one made out of milk crates I found while wondering was much more to my liking.
My husband liked the walk under the string arbor covered with vines that was tall enough for his six foot 8 frame to fit under.
and he identified all the implements where the parts were used to decorate this flower border filled with metal flowers made from old farm implements.
There was a stream populated by gnomes.
A giant Squash made out of old tires.
A bathtub in the middle of a woodland.
A stone stacking area where you could stack stones and meditate.
The butterfly garden sported a butterfly bench.
And the largest succulents I have ever seen grew in a vertical pallet garden with a smaller one filled with herbs nearby.
A prairie space covered with black-eyed Susan had a wonderful wind sculpture,
and in the same area was a dragon made out of an oat conveyor.
The fountain garden had some of the most interesting tile.
And the gate / door into the prairie was just cool.
I took one of my best art photos here too:
Hidden Hill Nursery was a wonderful little hidden Gem.
