Kakadu Plum

Terminalia ferdinandiana

The Story

Plant Bio

Terminalia ferdinandiana is a deciduous tropical tree native to northern Australia, characterized by a straight trunk, crooked branches, and an open, spreading crown. The tree drops its leaves during the dry season, displaying alternate, glossy green leaves clustered at the branchlet tips that turn yellow or red before falling.

This species is highly sought after for its smooth, fleshy green drupes, which are famous for containing exceptionally high concentrations of vitamin C. Small, creamy-white to greenish-yellow flowers appear on slender spikes in spring, followed by the tart, edible fruits.

Uses & Benefits:

Ornamental UsesFeatures an open, architectural canopy with glossy green leaves that turn yellow and red before shedding.
Practical UsesProduces edible, tart green drupes that are exceptionally rich in vitamin C.
Ecological BenefitsProvides negligible ecological value in North America due to its restricted indoor or greenhouse cultivation.

Planting

How to Grow

  1. Select a deep container filled with a highly porous, sandy potting medium to ensure rapid drainage.
  2. Position the plant in a location that receives full sun and maintains warm, frost-free temperatures year-round.
  3. Water deeply during the active summer growing season, allowing the substrate to dry out completely between waterings.
  4. Reduce watering to a bare minimum during the cool winter months when the tree sheds its leaves and enters dormancy.

Pro Tip

Do not mistake dry-season leaf drop for death; this deciduous phase is a natural survival mechanism, and watering must be severely restricted during this dormant period to prevent root rot.

Keep It Thriving

Care Guide

Do

  • Ensure the growing medium has excellent drainage to prevent waterlogging.
  • Provide maximum sunlight exposure to mimic its native open woodland habitat.
  • Protect the plant from any exposure to frost or freezing temperatures.

Don't

  • Do not overwater during the cool or dormant winter phase.
  • Do not plant in heavy clay soils or poorly drained containers.
  • Do not prune heavily into old, leafless wood.
