The Christchurch Botanical Gardens has six conservatories each totally different. Hot days or cold days there is always one to retreat to.
This is inside Cunningham House originally called the Winter Garden, opened in 1923. It's a two level tropical house.
Townend House. Built 1956, a flowering conservatory where a regular succession of flowering hot house plants are grown.
Another of my favourites is Garrick House. It contains the most extensive publicly owned collection of cacti and succulents in New Zealand and also contains a diorama depicting a desert scene representing from South Africa to South America painted by Gordon Lee the sign and label writer for the Botanical Gardens from 1956 to 1974.
If you're in Christchurch do take time out to wander and enjoy this wonderful space.
