But the real showstopper comes in spring when dense clusters of fragrant, deep purple-blue flowers appear, creating a spectacular display that’ll have your neighbors asking, What is that gorgeous plant?

Growing California False Indigo Successfully
The beauty of this shrub lies in its easy-going nature. Here’s how to keep your California false indigo happy:
Growing Conditions

Special Considerations
California false indigo has interesting wetland characteristics that make it adaptable to various moisture conditions. In arid regions, it can handle both wet and dry situations, while in mountainous and coastal areas, it typically prefers drier conditions but can tolerate some moisture. This flexibility makes it an excellent choice for gardens with varying water availability.
