Ilex crenata Green Thumb

Green Thumb Holly

Ilex crenata ‘Green Thumb’ is a dense evergreen shrub valued for its naturally narrow upright habit and small glossy dark green leaves. This Japanese holly forms a tight vertical column with fine texture, offering a more compact alternative to broader hollies. Its dense branching provides year-round structure with minimal pruning.
