Streetspire Oak
Streetspire Oak (Quercus robur x alba 'JFS-KW1QX')
Streetspire Oak (Quercus robur x alba 'JFS-KW1QX') is a narrow, upright hybrid oak selected for its strong vertical form, vibrant fall color, and resistance to mildew. A cross between English Oak and White Oak, this cultivar offers the best of both species�combining urban durability with refined, symmetrical structure, making it a top choice for street, commercial, and formal plantings.
