Baptisia, also known as false indigo, can be propagated by seed or stem cuttings

Seed propagation 

  1. In late summer or early fall, harvest the woody pods that have started to split open.
  2. Remove the round brown seeds inside.
  3. Soak the seeds in hot water overnight to soften their hard outer shell.
  4. Sow the seeds about 1/2 inch deep in a pot of compost with grit or vermiculite on top.
  5. Place the pot in a cold frame or unheated greenhouse.
  6. Ensure the soil doesn’t dry out.
  7. Transplant young plants into the garden in spring.

Stem cutting propagation

In spring, take cuttings from shoots that are still relatively soft. 

Dip the cuttings in rooting hormone.  Insert the cuttings into a potting mix of 3 parts composted bark to 1 part peat.  Keep the cuttings in a high humidity environment, such as a plastic tent.  Wait about 8 weeks for the cuttings to root. 

Baptisia plants are native to the prairies of southern North America. They grow well in well-drained soil in USDA planting zones 5-9.
