Common Name: Schmidtlow Zelkova Serrata
Zelkova serrata ‘Schmidtlow’ (often sold as ‘Wireless’) is a narrow, upright Japanese zelkova selected for its strong central leader, tight branching, and urban reliability. It’s a popular elm alternative, offering similar vase-like elegance with fewer pest and disease issues. Summer foliage is clean medium green, forming a dense yet refined canopy. In fall, leaves turn yellow to orange-bronze, sometimes with hints of rust, providing consistent seasonal color. The form stays columnar to narrowly vase-shaped, making it ideal where space is limited. This cultivar is heat-, drought-, wind-, and pollution-tolerant, and performs well in compacted soils—excellent for streetscapes and commercial sites. Size Width: 15–25 ft Height: 45–60 ft Hardiness USDA Zones: 5–8 Best Uses Street and boulevard tree (overhead-wire friendly) Urban and commercial landscapes Narrow lawn spaces and medians Elm replacement plantings Campus and municipal sites Note: ‘Schmidtlow/Wireless’ maintains a narrower profile than standard zelkovas, reducing conflicts with sidewalks and utilities while still providing shade.
