Deciduous & Flowering Shrubs
Crimson Pygmy Japanese barberry
Berberis thunbergii 'Crimson Pygmy'
Crimson Pygmy Japanese barberry forms a dense, spiny shrub generally 1–3 feet tall and 2–4 feet wide at maturity. Its reddish-purple summer leaves turn red in fall, while pale yellow spring flowers give way to red fruit that may persist into winter. Set it in a border or low hedge where its compact shape has room to spread and its spines stay clear of paths. Full sun brings stronger red foliage color; partial shade is also suitable. Choose well-drained soil, since wet ground can encourage root rot. Birds may eat the fruit and disperse its seed.
