Berberis thunbergii f. atropurpurea 'Helmond Pillar'

Columnar Purpleleaf Japanese Barberry, Purpleleaf Japanese Barberry

Berberis thunbergii f. atropurpurea ‘Helmond Pillar’ — commonly known as Helmond Pillar Japanese Barberry — is a distinctive upright, columnar barberry valued for its deep purple foliage and narrow, architectural form.
