Both Japanese barberry and common barberry (from Europe) are escapees from gardens, where they have become well established even though no longer for sale. Long arching canes of small leaves, with sharp spines at nodes, and bright red small oblong berries.
Beloved by landscapers for the purple color (of Japanese variety) and ability to prune into hedges. Escaped into the wild, can form large shrubs crowding out native species. It has been found that the moist environment of its root mass is haven for ticks.
