The plant will tolerate some sun, but full afternoon rays in summer tend to make it dull. Persian shield will grow to 4 or 5 feet and will become too leggy unless you pinch it occasionally to encourage fuller growth. Following cold winters, I prune away freeze-damaged stems. Following mild ones, I also prune pretty hard when we're out of danger of a freeze. Then I encourage new growth with an application of diluted fish emulsion, a source of nitrogen.
Persian shield likes water, but it needs a well-draining soil.
I've lost those that were planted where drainage was poor. American beautyberry, too, likes dappled or partial shade, as well as a moist but well-draining soil, so culturally it is a suitable Persian shield companion. It has a rather loose habit, stretching upward and outward about 5 feet. It is deciduous, losing its leaves for winter, and for this reason some would not plant it along the front of a house. I think just because a plant is deciduous it should not lose merit, but think about how this noteworthy shrub and the Persian shield look in the landscape in winter.
