Selecting Columnar Trees for Pacific Northwest Museum Landscape

Site-Specific Selection Is Essential

Without knowing your exact location (sun, soil, wind, hardiness zone), specific recommendations are risky. Trees perform best where native or adapted.

Process for Choosing

1. Visit a local retail nursery (not big-box). Staff know microclimate-adapted plants.
2. Describe: 25–30 ft tall, columnar, parking lot edge, screening, 3 in a row, near plums.
3. Ask for 3–5 options with pros/cons.

Likely Candidates for PNW

• Carpinus betulus 'Fastigiata' (European hornbeam) — 35 ft, narrow, tough.
• Quercus palustris 'Green Pillar' (columnar pin oak) — but check oak wilt risk.
• Liquidambar styraciflua 'Slender Silhouette' — 30 ft, very narrow, fall color.
• Prunus serrulata 'Amanogawa' (columnar flowering cherry) — 25 ft, spring bloom.
• Taxus baccata 'Fastigiata' (Irish yew) — evergreen, 20–30 ft, shade tolerant.

Final Step

Buy from the local nursery—they'll warranty and advise on planting.
