Most Cold Hardy Holly Trees

I will list the most cold hardy Holly trees used for hedges or as screening, not the shrubs. All these are hardy to USDA Zone 5 (-20°F). There are many more Holly trees, but are hardy to Zones 6, or 7 at the coldest. Zone 5 people still have hope for that broadleaf evergreen tree hedging!

'Steed's' Japanese Holly

6'-10' tall by 5'-6' wide

Makes the perfect hedging tree, or simply placed in the garden or along your house. Looks like a boxwood than a Holly.

'Sky Pencil' Japanese Holly

8'-12' tall by 1'-2' wide

Very upright. Perfect for blocking unwanted areas like power boxes, or great for along front of buildings for design. Branches bend and get deformed or snapped in heavy snow. In areas prone lots of snow wrap your plant with twine or rope to prevent this. Resembles Boxwood than Holly.

'Castle Spire' Holly

8'-10' tall by 3'-4' wide

This is one of the only true Holly looking plants with the spikes in the foliage. It is one of the only varieties that reach tree size that is hardy to Zone 5. Other varieeties are hardy toto zones 6 or 7 for coldest. Great for hedges, or around a buildings for design.

American Holly

20'-60' tall by 15'-35' wide

Next to 'Castle Spire' one of the only tree hollies for Zone 5. Perfect for hedging or larger screenings.
