Ulmus crassifolia
Also called Basket Elm, Southern Rock Elm, Red Elm
Cedar elm (Ulmus crassifolia) is a medium to large deciduous tree native to south-central North America, most common in Texas, that grows best on flat valley bottoms. It is tolerant of heat and grows well in warm, humid southern conditions, but it resists cultivation in cool northern climates.
Ulmus crassifolia Nutt., the Texas cedar elm or simply cedar elm, is a deciduous tree native to south-central North America, mainly in southern and eastern Texas, southern Oklahoma, Arkansas, and Louisiana, with small populations in western Mississippi, southwest Tennessee, and north-central Florida; it also occurs in northeastern Mexico. It is the most common elm tree in Texas. The tree typically grows well in flat valley bottom areas referred to as cedar elm flats. Its Latin name refers to its comparatively thick (crassifoliate) leaves; the common name cedar elm is derived from the trees' association with juniper trees, locally known as cedars.
U. crassifolia is extremely rare in cultivation in Europe and Australasia. Specimens were supplied by the Späth nursery of Berlin from the late 19th century. Henry (1913) and Bean (1988) note that it does not thrive in northern Europe, where the branchlets often die back. Three trees supplied by Späth to the Royal Botanic Garden Edinburgh in 1902 as U. crassifolia may survive in Edinburgh, as it was the practice of the garden to distribute trees about the city (viz. the Wentworth elm).
