Kindred Spirit Hybrid Oak (Quercus × 'Nadler' PP 17,604) is an exceptional deciduous shade tree prized for its remarkably narrow, upright form and durable landscape performance. A hybrid of English Oak and Swamp White Oak, it develops a dense, tightly columnar crown with glossy dark green leaves that turn yellow to golden brown in fall. Spring catkins are followed by acorns, providing seasonal interest and wildlife value. Highly resistant to powdery mildew, this adaptable oak tolerates urban conditions and dry periods once established. Its slender silhouette makes it an outstanding choice for narrow yards, street plantings, property borders, and formal landscapes where space is limited.
