Kakadu Plum

Terminalia ferdinandiana

The Story

Plant Bio

Terminalia ferdinandiana, commonly known as the Kakadu plum, is a deciduous tropical Australian tree reaching four to eight metres in cultivation, with an open, spreading canopy of pale green, broad leaves clustered at the branch tips. The tree sheds its foliage during the dry season, followed by a flush of fresh bronze-green growth and spikes of small, cream-coloured flowers as the wet season approaches.

This species is highly valued for its smooth, fleshy, yellowish-green stone fruits that ripen after the wet season. The rough, dark grey, flaky bark provides structural interest when the branches are bare during its winter deciduous phase.

Uses & Benefits:

Ornamental UsesProvides a distinct architectural form with its open canopy, flaky grey bark, and seasonal deciduous habit.
Practical UsesProduces highly valued edible fruits rich in vitamin C, suitable for preserves and bush tucker gardens.
Ecological BenefitsProvides nectar for native bees and insects, and foliage and fruit for native birds.

Planting

How to Grow

  1. Select a planting site in full sun with highly draining sandy loam or gravelly soil.
  2. Dig a hole twice the width of the root ball and plant at the same depth as the container.
  3. Water deeply to settle the soil, then restrict watering during the cooler dry season.
  4. Apply a light application of balanced native slow-release fertiliser only during active summer growth.

Pro Tip

Replicate the wet-dry tropical rhythm by keeping the root zone dry during cool winter months and providing deep, periodic watering paired with intense heat and absolute drainage in summer.

Keep It Thriving

Care Guide

Do

  • Ensure absolute drainage to prevent root rot.
  • Allow the tree to drop its leaves and rest during the dry season.
  • Protect young trees from any frost exposure.

Don't

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

Common Questions

Kakadu Plum questions

What zones can Kakadu Plum grow in?

Kakadu Plum is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

When does Kakadu Plum bloom?

Kakadu Plum typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Kakadu Plum need full sun?

Kakadu Plum does best in full sun (6+ hours).

Is Kakadu Plum drought tolerant?

Yes — once established (usually after the first full season), Kakadu Plum handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
