Adenandra calycina is easily propagated through seed and is commonly used by nurseries. The following steps are important in propagating Adenandra calycina through seeds:
- Collect mature seeds from the plant during autumn.
- Clean the seeds and dry them in a cool, dry place for two weeks.
- Store the seeds in a cool, dry place at a temperature of 4 °C degrees to maintain dormancy.
- Sow the seeds in the spring in a seed tray with a well-draining soil mix and water gently.
- Place the seed tray in full sunlight and water regularly to keep the soil moist.
- The seeds of Adenandra calycina should germinate within two to three weeks.
