Bush Food Note

The blue fruits of Elaeocarpus angustifolius are edible when slightly overripe and soft, though the taste can be bitter if unripe.

• Preparation: Separate the bright blue skin from the greenish flesh. Mix the fresh fruit with water to create an edible paste.
• Seeds: Each fruit contains a rough woody stone with up to five seeds.

How to Grow

1. Sowing Instructions:

   • Seeds are encased in a tough woody stone, so scarification (lightly sanding the surface) or soaking in warm water overnight can improve germination.
   • Sow seeds in a well-draining seed-raising mix and cover lightly with soil.

2. Position:

   • Choose a sunny spot with protection from strong winds.
   • Ideal for subtropical gardens or areas near creeks and riverbanks.

3. Care Tips:

   • Water regularly during establishment; prefers consistently moist soil.
   • Mulch around the base to retain moisture and regulate soil temperature.
   • Fertilise with a slow-release native plant fertiliser for optimal growth.
