This entry has yet to be reviewed and approved by L2G editors.
Purpleleaf Japanese barberry is a dense, upright to arching shrub that originates from eastern Asia. It has glossy, red-purple leaves that emerge red turn shades of red, purple and orange in fall. In spring, small but showy yellow flowers cover 'Royal Cloak'. Bright red berries, which are attractive to birds, appear in late summer to fall and persist long after the leaves are shed in the fall.
This is a tough, fast-growing and sun-loving plant that is tolerant of many soil types and urban sites. It has been known to self-sow and can become somewhat invasive. Though thorny, it is suitable for hedges and barriers and makes a nice accent plant for mixed borders. Take care not to plant barberry in areas where children play.
Berberis thunbergii is sometimes considered an invasive plant particularly in the northeastern United States. It can form dense thickets in natural areas where it changes soil characteristics and displaces wildlife. For more information about the invasiveness of barberry see the National Park Service’s factsheet at http://www.nps.gov/plants/alien/fact/beth1.htm . Also, some species and cultivars of barberry host the plant disease black stem-rust of wheat which causes serious losses in wheat yield. The sale or transport of susceptible or untested species may be prohibited in some parts of the United States and Canada. For more information about the disease see the United States Department of Agriculture factsheet at http://www.aphis.usda.gov/plant_health/plant_pest_info/barberry/background.shtml
