Nurseries really are not my thing. But if they were, I can see spending some time here, because this place is pretty awesome. It is huge. The center is where you enter - and exit - but the outer section is where the really good stuff is found.
You can find smaller plants in the tent area behind the building, but you can grab all sorts of outdoor furniture and trees of all shapes and sizes all around the fenced-in space surrounding the building.
The only real downside is that the space is so big you can get a bit lost. Not lost as in they need to send a search and rescue party, but lost as in you feel as if you really need help finding someone to help you out, and in the whole time that I was there, I swear I am not sure I saw a single employee. That could really do wonders for the place.
