Sawtoothed Japanese Aucuba

Sawtoothed Japanese Aucuba (Aucuba japonica 'Serratifolia')

Sawtoothed Japanese Aucuba is a shade-loving evergreen shrub distinguished by elongated, glossy green leaves with pronounced serrated margins. Its dense, upright habit brings durable year-round color and texture to foundations, woodland edges, and protected entries.

Distinctive Features
