Berberis buxifolia ‘Nana’ is a compact, evergreen barberry valued for its dense habit and year-round structure. Small, glossy dark green leaves form a tight, rounded framework that stays neat with little attention. In late spring to early summer, clusters of small yellow flowers appear, adding subtle seasonal interest and attracting pollinators, sometimes followed by dark berries later in the year. Tough and adaptable, this dwarf selection copes well with wind, coastal exposure, and poor soils, making it a reliable choice for low hedging, borders, and compact planting schemes where durability and evergreen form are key.
