Planting / harvesting notes

Soak in water overnight and/or scarify (scratch lightly) and sow about an inch deep in moist soil at 70 degrees Fahrenheit. Covering your seedling flat with a humidity cover like a plastic bag until germination might help create even moisture for the seeds. Should germinate within 30- 60 days. Plant will need years before blooms are produced.

Seed keeping notes

For seed saving, harvest the pods when their shells have become dried and crispy on the plants. Lay out the pods in a dry, sunny place to dry down further. Shell the seeds and lay them out in a well ventilated place away from direct sunlight for at least another few days to a week before storing for next year.
