Adansonia gregorii, commonly known as the Australian Baobab or Boab, is a distinctive bottle-shaped tree native to the Kimberley region of Western Australia and Northern Territory. Seeds display physical dormancy and germinate readily once water permeable, making them relatively easy to grow from seed with proper scarification and warm, moist conditions. This iconic Australian species is valued for its drought tolerance, edible seeds and fruit pulp, and cultural significance to Indigenous peoples.
Before sowing
Scarify seeds mechanically by light sanding or nicking the seed coat, then soak in warm water for 24-48 hours with frequent water changes. Seeds have physical dormancy and germinate readily once water permeable.
Sowing
What to expect
Tips
Keep seeds at constant temperatures between 20-30°C, ideally 25-30°C for faster germination. Maintain high humidity by covering container with clear plastic but ventilate occasionally to prevent mold and fungal growth. Water regularly but avoid waterlogging to prevent root rot. Do not use boiling water treatment as seeds are sensitive to high heat. Once germinated, keep seedlings in their germination environment for the first 3 months while they develop their characteristic taproot system. Transplant carefully to avoid damaging roots. Provide bright light and ensure well-drained substrate after germination.
