Stan,
I have never planted any of the redbud(Cercis canadensis) seeds,but I have transplanted many volunteer seedlings over the years. They sprout all over the place.Usually in the flower beds or under the decorative shrubs around my place. Some have even sprouted in the control lines of my concrete car pad.They usually transplant well-although I do water them for the first few weeks until they become more established. BTW it is a very pretty tree and the bees just cover these small trees every spring.
