It's quite easy. Boil water, pour water in a mug or cup, and place seeds in very hot water, and allow seeds to soak overnight.
Seeds will germinated close to 100% within a week when sown in potting mix.
This method works with almost any pea family member including Cercis, Baptisia, Thermopsis, Indigofera, etc.

Carol: That is really interesting. I will cross-post your suggestion on the National Home Gardening Club website as well.

Do the seed pods have to turn black or can one propagate with this method using pods that are still green?

My false indigo comes from division. I bought it from someone who sells perrenials from her garden. I've had the one I bought from her for 4 years and plan to divide mine this fall.

When do you plant the seeds? August, September? or in the spring? My plant is getting huge, and I have a lot of the seed pods, and would give it a try-starting from seeds. Thank you.
