The pods split 4-6 weeks after flowering and the seeds should be kept in the pod until ripe. Fresh seed may be sown immediately in pots or where they are to grow in the ground. The germination of stored seed improves with cold/moist stratification (Steffen 1997).Seeds average approximately 68,000 seed/lb and the recommended planting rate is 25 lbs/acre. Blooms in 1-2 years from seed. Stem cuttings can be taken during the growing season, dipped in rooting harmone, and rooted in sand or potting soil.
