Seed propagation
The seeds of Hoffmannseggia melanosticta (Schauer) Gray can be directly sowed in a well-draining soil mix in the field or in pots. Here are the steps to follow:
- Select healthy seeds from a mature plant
- Remove any debris or chaff from the seeds
- Soak the seeds in room temperature water for 24 hours
- Sow the seeds 1-2 cm deep into the soil mix
- Water the soil gently
- Keep the soil moist but not waterlogged
- Germination should occur within 2-4 weeks
