Interesting Facts

Plant juice turns purple on exposure and is a fair substitute for true indigo in making blue dye.


Grow in full sun and average garden soil. Tolerant of most soils as long as they are not wet. Water well when planting and regularly for several weeks until it is established. Site your Baptisia carefully as it will not recover quickly from being moved. A long tap root contributes to drought tolerance, but is not conducive to transplanting. Move it immediately following flowering and water well if you must move it.
