    Growing offerings of seeds, bulbs, as well as tubers and rhizomes grown and collected from KoruKai Herb Farm, Banks Peninsula.

    Grown in biological, organic, alive soil, chemical-free, synthetic fertiliser-free, herbicide-free.

  • Plants

    Plants are sold and shipped during their winter dormancy from July until mid-September. This allows us to ship them bare-rooted, and the transplanting success rate is significantly higher than sending pots with soil in mid-summer and transplanting seedlings during their growing period.
