The Geographic Plant Collections
This collection has plants from all around the world, grouped by continent. These descriptions mention key features of each grouping.
About the Geographic plant collections
The Geographic plant collections are incredibly diverse, displaying plants from around the globe. The collections are displayed in formal borders of trees, shrubs and herbaceous plants. As the plants must be tolerant of Dunedin's climate they are mainly from temperate regions.
Plants for these collections have often been acquired through the International Seed Exchange Programme. We prefer to grow plants from seed of known wild origin for several reasons including:
- To help understand the form and performance of the plant
- To help with conservation of naturally occurring genetic diversity

The Australian Borders
There are many drought tolerant plants that enjoy full sun. Plants include Callistemon, and Grevillea. Many of the plants from this area have unusual bottlebrush-like flowers. To the west of the collection is a glade of mature Eucalyptus.
The Southern African Border
This includes many species endemic to South Africa, including Restios and members from the family Proteaceae. With 10% of the world's flowering plants found in South Africa, we are able to represent only a small proportion of the species from this region.
The Mexican Border
This area shows, amongst others, many dahlias and plants from the group Agaveacae, including a 2 metre tall Agave. Mexico is a 'megadiverse' country, having over 65 thousand plant species. We grow some of the hardier species from this region.
The South American Border
This border mainly consists of mature tree and shrubs. Plants range from the bromeliad Puya to the wonderful non-invasive clump-forming bamboo Chusquea culeou.
The North Asian Border
A diverse range of vegetation is represented due to the geographical variation within North Asia. Plants range from fan palms to a mature specimen of Diospyros kaki (Chinese persimmon).
The Shanghai Border
This collection of plants was gathered to celebrate Dunedin's sister city status with Shanghai.
The Himalayan Border
This is an area with vegetation reflecting the huge mountainous terrain of the region. A mature specimen of Magnolia doltsopa (also known as Michelia doltsopa) lights ups the collection in summer with its fragrant creamy magnolia-like flowers.
The North American Border
This area shows plants from the temperate regions to the warmer Californian coast. In autumn, the specimen of Acer circinatum is ablaze with autumn oranges.
