Sowing instructions
Chelidonium majus can be sown in a pot indoors in Central Europe from March or directly into a bed or balcony box in April.
Greater celandine is a light germinator, the seeds are only sown on the substrate, but are not covered with it. I used a mix of peat-free herb soil and bird sand.

The soil should be slightly moist but not dripping wet. To prevent the seeds from drying out, I like to use glass jars for growing light germinators.

The seeds can be soaked for a few hours before sowing, but they also germinate well without this pre-treatment. At 18 to 24 °C, the first cotyledons may appear after two weeks.
Indoor locations for germination and cultivation can be bright to partly sunny, with morning or evening sun.
