I like to visit gardens and go on garden tours when I am on vacation. Sometimes they are hard to find and they can keep odd hours but I enjoy it none the less. I am asking for recommendations of gardens you have been to or public gardens in your area. They do not need to be limited in any way I would love to hear about European gardens and I have heard of some great ones in Canada too. Problem is it is always in passing and never written down. So all I can remember is there are some great gardens in Canada. I will kick it off by listing The Garden Conservancy email@example.com as a great resource for tours of private gardens across the US. I have also been to and would recommend Longwood Gardens in New Orleans (pre Katrina) Huntington Gardens in Pasadena Calif. I look foreword to everyones contributions.
