A true garden specimen shrub with almost ferny finely cut foliage and yellow flowers; soft wispy leaves fountain over trunk, usually grafted on a standard to a certain height; supremely hardy.
Walker Caragana has yellow pea-like flowers hanging below the branches in mid spring. It has light green foliage throughout the season. The deeply cut ferny pinnately compound leaves turn yellow in fall. The fruit is not ornamentally significant. The smooth olive green bark adds an interesting dimension to the landscape.
Walker Caragana will grow to be about 6 feet tall at maturity, with a spread of 3 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 medium rate, and under ideal conditions can be expected to live for approximately 30 years.
This shrub does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. 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. This is a selected variety of a species not originally from North America.
