Cardamine corymbosa
Also called New Zealand Bittercress, New Zealand Bittercrass
A small, low, creeping annual from the cabbage family, native to subantarctic islands and now best known as a weed in nursery pots and polytunnels. Grown as a plant it is a minor cool-weather groundcover; the key to growing it is cool, moist conditions.
Cardamine corymbosa, commonly known as the New Zealand bitter-cress, is a flowering plant in the family Brassicaceae. Native to the subantarctic islands of Australasia, it has become an invasive species in plant nurseries. The specific epithet refers to the structure of the inflorescence.
The plant is native to New Zealand’s subantarctic Auckland and Campbell Islands, as well as to Australia’s Macquarie Island, where it occurs in alpine tundra and rocky coastal habitats. It has been accidentally introduced to other parts of the world, including North America and Europe, where it is a weed of nursery crops grown in polytunnels.
