Planting & Growing

White False Indigo will grow to be about 24 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 24 inches. It tends to be leggy, with a typical clearance of 1 foot from the ground, and should be underplanted with lower-growing perennials. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 25 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

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 considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. 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. It can be propagated by division.
