Banksia prionotes, commonly known as acorn banksia or orange banksia, is a native Australian shrub or small tree reaching up to 10 meters in height. Named for its acorn-shaped flower buds that gradually open to reveal bright orange cylindrical flower spikes, this species is valued as an ornamental plant and important cut flower. Seeds germinate readily without pre-treatment, typically within 14-40 days at optimal temperatures of 20-25°C.

Tips
Sow seeds in individual containers to avoid root damage during transplanting. Maintain moist but not waterlogged substrate throughout germination. Best sowing times are autumn or spring. For pre-germination method, use closed containers with moist vermiculite at 20-25°C for rapid germination in 1-2 weeks. Do not use phosphorus-containing fertilizers with seedlings as Banksia species are phosphorus-sensitive. Keep seedlings in bright light but protect from direct sun exposure. Once seedlings reach 5-10cm height, transplant into individual pots. Do not discard seeds that fail to germinate immediately as dormant seeds may require extended periods for optimal conditions.
