There is a great deal of information re Propagation to be found on Google. I have always found that this type of seed has varying degrees of germination. So other than treatment with sulphuric acid to damage the seed coat. I sow a lot of the seeds very thickly in the open ground and await the first to germinate. Much dedpends in the age of the seeds.As this is a member of the Pea Family . It is likely to do best in a well drained neutral soil. It is best to feed with a general fertilizer having low percentage of nitrogen as it makes this for itself by bacteria on the roots..

Hi'' were you live is ideal, it likes full sun and well drained soil,how ever the slitest frost will damage it, and it is subject to mildew leaf spot and root deseases, but it is tolerant to drought and salt, a number of medicine's are made from the fruit, one of its names is the medicine tree ,but the seeds are poisonous, the name I like best is the golden shower tree, hope that helps.
