Planting & Growing

Blue False Indigo will grow to be about 3 feet tall at maturity extending to 4 feet tall with the flowers, with a spread of 24 inches. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 25 years.

This plant does best in full sun to partial shade. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil type, but has a definite preference for alkaline soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This species is native to parts of North America.
