Quercus × bimundorum 'Streetspire' (JFS-KW1QX) is a narrowly columnar oak prized for its strong structure, disease resistance, and vibrant seasonal color. Dark green, mildew-resistant foliage remains attractive throughout the growing season before turning rich red in autumn. Its sturdy branching habit, featuring wide crotch angles and upsweeping limbs, provides excellent storm resistance and creates an attractive winter silhouette after the leaves drop. Similar to Crimson Spire™, 'Streetspire' sheds its foliage cleanly in fall rather than retaining brown leaves through winter. Reaching approximately 20–25 ft tall and 8–10 ft wide in 10 years, this elegant oak is an excellent choice for streetscapes, urban settings, and landscapes where space is limited.
