Tayuling 2004. Native to Taiwan at mid to high elevations, this was of interest to us for its evergreen habit, the glossy green leaves holding fast, we expect, in temperatures down to 18 to 20F. Though loving damp conditions, these do not require quite the riparian situation of many alders. Fast growing, to 30-40 ft tall, in sun to part shade with summer water. Stand back! Ultimate cold hardiness is not yet tested but these will remain healthy, though deciduous, to the bottom of USDA zone 8.
