Christchurch is known as the Garden City in New Zealand. It is one of the more expansive botanic gardens we visited. The ilex cafe is a great place to eat, especially if you sit outside and enjoy the birds. You can punt down the Avon, and enjoy the nearby museum. They also host special exhibitions, like this one featuring the flower costumes of Jenny Gillies in its Enchanted Garden exhibition.
Jenny Gillies is an award-winning fabric artist, who uses the flora of Christchurch as inspiration. At this exhibition was a great video of how these costumes are used in performances. There are a couple of videos embedded below.
