The Field Maple cultivar 'William Caldwell' was cloned from a seedling discovered at Knutsford, England, in 1976 by Donovan Caldwell Leaman, head nurseryman at the now-defunct William Caldwell Nursery. The tree was released to commerce in 1980.

The tree is noted for its fastigiate shape, and foliage which turns orange / red in autumn where planted on acid soils, not yellow as with the species.[1]
'William Caldwell' is largely restricted to the UK, where it remains uncommon; it was imported by the U S National Arboretum, Washington, D. C. in 2010. The tree is reputedly difficult to propagate.
The cultivar was known as 'King Canute' until 1983; Canute was the emblem and trademark of the William Caldwell nursery.
The cultivar is named for the William Caldwell nursery (ceased trading c. 1990).
