Canterbury-Otago tussock grasslands
Canterbury-Otago tussock grasslands
The Canterbury-Otago tussock grasslands cover the dry eastern plains and inland basins of New Zealand's South Island, stretching between the Pacific coast and the Southern Alps across the Canterbury and Otago regions, taking in the Canterbury Plains, the Mackenzie Basin and the Maniototo. Lying in the rain shadow of the Alps, the ecoregion has a dry climate with warm summers and cold winters, and its highland basins are the driest ground of all, receiving less than 500mm of rain a year. Where coastal broadleaf and kahikatea (Dacrycarpus dacrydioides) forests once grew, fire and clearance have left open communities of drought- and fire-hardy native tussock grasses such as hard tussock (Festuca novae-zelandiae), silver tussock (Poa cita) and tall snow tussocks (Chionochloa). The grasslands shelter endemic reptiles including the Otago skink and grand skink, whose range has shrunk by roughly 90 percent through land modification, overgrazing, weeds and recurring fires. For gardeners, the region is home to ornamentally useful native genera such as the cypress-like shrub Hebe cupressoides and the spiky alpine herbs Aciphylla.

Use this as the broad planting pattern for the region: Temperate prairies, steppes, and pampas of grasses and forbs with few trees, under continental climates of hot summers and cold winters. Their deep, fertile soils have made them among the most extensively converted biomes for agriculture. For garden decisions, pair that context with the plant list below, then narrow by your site's light, water, soil, and mature-size constraints.
