Pruning Baptisie bleue – Faux-indigotier

Pruning is not required. When the time comes to shape the plant, it is easy to cut back and use as a mulch plant. Other gardeners like to remove the dark seed pods as a mainenance activity.


Insects are generally not a serious problem on baptisias. A weevil may damage seeds, but does not change the appearance of the plant. May be toxic to many insects, but is a host plant for several butterfly larvae. Diseases are very rarely a problem. Fungal problems may occur in crowded or moist conditions.

Baptisia is deer tolerant.

Baptisia’s are in the legume family and are a nitrogen leveler. However, they are not edible.

The Baptisia name comes from the Greek root bapto, (to dip or to immerse.) People used the juice extracts to dye their fabrics. Throughout the years, baptisia’s provide indigo dye to create a blue color to a variety of textiles and fabrics. False indico was the first subsidized agricultural plant in America.
