'Crimson Spire' Columnar Oak
FamilyFagaceae
Quercus × 'Crimson Spire' is a hybrid oak with a narrow columnar habit, resulting from the cross between Quercus robur fastigiata and Quercus rubra, combining rapid growth, dense foliage, and a structured vertical silhouette. Its dark green foliage turns deep purplish-red in autumn, offering a striking colorful display. Its naturally narrow and regular habit makes it an ideal choice for tall informal hedges, avenues, or formal gardens where space is limited. Very hardy, tolerant of pollution and urban conditions, it prefers a sunny exposure and well-drained soil. 'Crimson Spire' combines architectural form, remarkable autumn coloration, and low maintenance, perfect for elegant and lasting verticality in the landscape.
