Height & Spread
Can grow up to 1.5 metres high and 1.5 metres across.
Best sown in Spring or Autumn.
Where to sow
In rows inside an easily shifted container (punnet).
Where to grow
In a sheltered, well drained site in full sun. Punnets recommended.
Spread seed thinly. Barely cover the seed. After 2 weeks cover the container in a plastic bag and place into a fridge for a further 3 weeks. Then return to normal temperatures.
Keep seedbed evenly moist during germination period, including refrigeration time.
Stratification (the refrigeration process) is the gardeners' way of mimicking Mother Nature's cold Winter conditions. In the wild, "seed dormancy" is overcome by the seed spending time in the ground through cold Winter spells. This breaks down the hard seed coat (in combination with moisture and bacteria). When the seed is reintroduced to warm conditions, its biological clock thinks it is Spring, and therefore time to germinate.
New Zealand natves often take a little while to germinate. Please be patient, they are worth the wait!
