Japanese barberry is an extremely hardy and attractive shrub that can become invasive, although the one in my Iowa garden has not been problematic. The leaves have a purplish red sheen from spring to fall with small yellow flowers in late spring. Although Japanese barberry can be propagated by root stem cuttings, transplanting the original plant is not recommended. If you would like a shrub that tolerates pollution and average to poor soils, Japanese barberry is the perfect choice.

Please note that the Zones listed above are USDA Hardiness Zones and are only given as a rough indication of whether a plant will grow and thrive in your area. Temperature variations and unusual weather conditions can affect plant survival. To assist plant survival during the winter, you may wish to place mulch over the areas in question or plant the flowers in an area away from walls or cement. Additionally, digging up bulbs and roots to overwinter indoors may be preferrable to keeping them in the ground.
