Family
Berberidaceae

Berberis thunbergii 'Royal Cloak', or Japanese barberry 'Royal Cloak', is a vigorous and very colorful ornamental shrub, prized for its dark purple foliage with reddish-purple highlights, which maintains remarkable intensity throughout the season. Its ample, well-structured bushy habit allows it to play a strong role in decorative hedges, contrasting beds or background plantings. In spring, small pale yellow flowers appear discreetly, followed by decorative red berries that extend visual interest into autumn. Robust, undemanding, and naturally deterrent thanks to its thorns, 'Royal Cloak' adds depth, structure, and character, while remaining easy to integrate into landscape designs.
