Facts

  • Discovered during a scientific survey in 1945
  • Grows to 10m tall
  • Vigorous climber
  • Flowers are cream-coloured and tubular
  • Popular in cultivation

Saved from certain extinction

Tecomanthe speciosa was on the verge of extinction when it was discovered, thanks to feral goats. Thankfully the goats were eradicated from the island in 1946 which restored the island’s ecosystem balance. The remaining wild specimen has not flowered for over 50 years, probably because the forest canopy creates too much shade.

Horticulturalists took cuttings from the original plant. Ten years later the plant finally set seed. As a result it has since become a popular garden climber.


Climbing safely

A vigorous twining climber, T. speciosa can grow up to 10m tall. We don’t want precious climbers like this to grow directly onto the Temperate House structure because it might damage the plant or the architecture. We’ve designed brackets to allow climbers to grow safely along the wires strung between them.

Three Kings Islands are called Manawatawhi by Māori
