How to grow
How To Grow False Indigo From Seed: 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.
False Indigo care includes following a regular watering schedule the first growing to encourage a good root system. After establishement, these are quite drought tolerant plants. Also, trim the plants back in the fall as they turn black with the first freeze.
