Banksia prionotes (Acorn Banksia) is a native Australian shrub valued for its distinctive acorn-shaped orange flower spikes and commercial cut-flower potential. Seeds germinate readily in 14-40 days at 20-25°C without pre-treatment, though smoke primer discs enhance germination rates. The species requires light, high humidity, and excellent drainage during seedling establishment.
Before sowing
No pre-treatment required. Smoke treatment via Smoke Seed Primer is optional and improves germination success. Seeds germinate readily without treatment.

What to expect
Tips
Use well-draining peat-perlite or sand-based substrate to prevent root rot. Maintain high humidity in a transparent covered container with daily air exchange. Provide bright indirect light without direct sun exposure. Keep substrate moist but never waterlogged—Banksia roots are sensitive to wet conditions. After germination, transplant seedlings to individual pots when large enough to handle. Do not use phosphorus-rich fertilizers on Banksia seedlings. Be patient; some seeds may germinate beyond 40 days if conditions are suboptimal.
