Seed cleaning:
No further cleaning is required. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
From two collections, the seed viability were high, ranging from 80% to 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
