Growing notes

  • Native to New Zealand — widespread across both islands
  • Distinct from the kowhai already in the database (S. tetraptera) — S. microphylla has much smaller leaflets and a more delicate habit
  • Major nectar source for tūī and bellbird — flowers in late winter when little else is in bloom
  • WARNING: All parts (especially seeds) toxic — keep seeds away from children
