A cultivar of American origin, ‘White Tigress’ was introduced to the trade in 1995 by the Roslyn Nusery of Dix Hills, New York State (Jacobson 1996). Whatever its parentage, it makes a fine tree of strong growth and possibly one of the most heat tolerant of snakebark maples (Breen 2019). Often multistemmed (Armitage et al. 2014), its bark is prominently striated and is among the best of the section for this character (Lancaster 2017). Roy Lancaster (2017, p. 290) describes it as ‘an excellent ornamental tree with a vase-shaped crown especially attractive in winter, while the big, bold, five-lobed leaves turn a bright yellow often with orange tints early in autumn’. A tree in Roy Lancaster’s private garden was around 6 m tall in 2017 (Lancaster 2017). The UK and Ireland Champion at Thenford House, Oxfordshire, stood 8 m tall when last measured in 2019 (The Tree Register 2019).
