The Wintergreen Barberry is a dark shaded evergreen that blossoms into clusters of yellow or red-tinged flowers during the late springtime. These are followed by black fruits in the autumn. It’s quite a large plant, although is slow growing and can take 20 years to attain its full height. This hardy, easy to grow plant requires little on-going maintenance, making it the ideal choice for the time-short gardener. Be aware that Berberis julianae is toxic if ingested, so perhaps not the best if you have small children.
