We’ve been trialing this Japanese holly a long time to be certain it lives up to its name. Straight & Narrow® is exactly that. Growing 6’ tall and 18’ wide, Straight & Narrow® is so much better than 'Sky Pencil' and 'Sky Sentry'. This plant has strong branches that remain upright and don’t splay out as it ages or faces the elements. Leaves are flat, not cupped, shiny dark green and remain nice looking through winter. Male. Destined to become THE columnar Japanese holly of choice for retail and landscape. Bred by Plant Introductions, Inc.
