I have wild white indigo growing but its only a couple years old. It takes about three or four years before it generates seed pods. And last season we had a severe drought so that may have set it back another year before it produces anything.

They are fairly easy to grow from seed. Like most natives they do need a cold stratification. And the seed pods are often invaded by birds and insects - lots of time I have collected emptied pods....

False indigo seeds need 'scarification' plus stratification for good germination success. Scarification is a technique for scratching the tough outer seed coat, such as with sandpaper or a file, to allow moisture to penetrate and begin the germination process. Most legume seeds need this. In nature, the seed coats probably erode gradually over time -- or perhaps they become damaged when the seed pod is digested by herbivores.
