I take my grandaughter to a small arboretum (sorry) for some fun and education. It's free and we always have a great time. There aren't any signs to discourage the picking of flowers, but common sense says DO NOT PICK THE FLOWERS. I appreciate the staff's care and dedication to the upkeep of the greenhouse. Emily can smell, look and admire the flowers and foliage. They also have a parrot, budgies and fish. There are signs that say "don't feed". but I have stopped folks from trying to feed and have no qualms in calling them out. Bottom line: signs don't matter. I appreciate your concerns and would have stated your original concern. After all, you won't see them again.All the best.
