Columnar English Oak

Quercus robur (KWER-kus ROH-bur fas-tij-ee-AY-tuh)

Family: Fagaceae Non-native Canopy (>40 ft)

‘Fastigiata’ or Upright English Oak is an upright, columnar, deciduous tree that matures into a dense elongated oval shape with a short trunk and makes a striking landscape specimen. It is susceptible to powdery mildew in humid areas and planting in full sun with adequate airflow helps decrease this problem. The cultivar 'Attention' is more resistant and is also columnar. Plant in full sun in well-drained acidic or slightly alkaline soil. This tree is tolerant of salt, drought and urban conditions. Use as a hedge or as a specimen in small areas where wide branching is a concern. Propagation is from seed but doesn't always grow true. It is a host plant for the larvae of the Imperial moth ( Eacles imperialis ), as well as numerous butterflies, including Banded hairstreak ( Satyrium calanus ), Edward's hairstreak ( Satyrium edwardsii ), Gray hairstreak ( Strymon melinus ), White-m hairstreak ( Parrhasius malbum ), Horace's duskywing ( Erynnis horatius ), and Juvenalis duskywing ( Erynnis juvenalis ).
