Castle Wall Holly
Ilex x meserveae ‘Heckenstar’ · an upright male blue holly
A compact, upright blue holly with small, glossy, spiny leaves, for narrow hedges, screens and foundation plantings. It's a male, so it won't berry, but one plant pollinates several Castle Spire hollies nearby. Give it acid, well-drained soil in sun or part shade.
