Pinus nigra Arnold Sentinel

Arnold Sentinel Austrian Pine

Arnold Sentinel Austrian Pine (Pinus nigra ‘Arnold Sentinel’) brings a narrow, upright shape to a garden. Branches angle upward and carry bright green needles, emphasizing height without the broad spread of a typical Austrian pine.

Its vertical form suits a focal position beside lower or rounded planting. Give the tree enough space to retain its natural outline as the crown continues to develop.

Choose a sunny position with soil that drains freely. Water during establishment and leave enough room for the branches to develop without crowding.
