- Sow the seeds indoors from March-June or September-November in a well-prepared seedbed.
- Sow the seeds thinly on the surface and lightly cover with a fine layer of soil or grit.
- Keep the soil consistently moist until seedlings emerge.
- Seeds will usually germinate within 14-28 days.
- Germination can be slow and may require cold stratification for 4-6 weeks, then return it to warmth.
- Once seedlings are large enough to handle, thin them to 10-15 cm apart to allow room for growth.
- Choose a sunny or partially shaded site with well-drained soil for best growth and flowering.
- Gradually acclimatise any indoor-sown plants to outdoor conditions before planting out.
- Water regularly during dry spells until established, but avoid waterlogging.
- Plants produce clusters of bright yellow, cup-shaped flowers in spring, which are excellent for wildlife gardens, meadows, and native plantings.
- Allow some seed heads to mature if you want natural self-seeding for the following season.
