That was what we were thinking originally. There are a lot of wonderful gardens out there that I would not consider being botanical gardens. Many towns in our area have rose gardens that are cultivated by a local group of dedicated gardners. These garden could be put into the botanical garden category, but I have always viewed botanical gardens as much larger, cultivated by specialist and having a rare collection of plants that woul not grow in that area naturally.
That makes me wonder if it would be go back to the original idea of having a category for gardens. Have botanical gardens be one of the detail categories under that, along with categories for Rose Gardens, Dahlia Gardens, Cactus Gardens, Arboretums, Japanese Gardens, and what ever else we could think of. This way if you are visiting a town and want to see some gorgeous flowers in a city park with no additional cost to you - you would have the information that you need.
Does someone want to propose a concludsion here on the forum and try to help us get moving forward. I will do anything I can to help make it possible, but I am the new kid on the block compared to others.
