Planting & Growing
Delta Blues™ Chaste Tree will grow to be about 8 feet tall at maturity, with a spread of 8 feet. It tends to be a little leggy, with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 50 years or more.
This shrub does best in full sun to partial shade. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments, and will benefit from being planted in a relatively sheltered location. This is a selected variety of a species not originally from North America.
