10+ Blue False Indigo Wildflower Seeds-Baptisia Australis-Beautiful Shrub-like Hardy Perennial-B662.
This shrub-like hardy perennial is in the pea family and prefers cool climates. It has an upright growth, pea-like blue flowers followed by dark, shiny pea pods and attractive foliage. Also called Wild Indigo or Blue False Indigo, this interesting native prefers at least 6 hours of sun each day. False Indigo care includes following a regular watering schedule the first growing to encourage a good root system. Also, trim the plants back in the fall as they turn black with the first freeze.
Blue False Indigo grows well from flower seeds, and historically the plants used to be in demand for the dye that was made from the blue flowers. Baptisia australis seeds have a hard outer coat so a cold/moist treatment before starting the flower seeds indoors is needed. Or, directly sow the False Indigo seeds directly outdoors in the fall, and all the harsh temps of winter to soften the seed coat naturally.
