Elm

Elms are deciduous and semi-deciduous trees comprising the genus Ulmus, family Ulmaceae. Elms first appeared in the Miocene period about 40 million years ago. Originating in what is now central Asia, the tree flourished and established itself over most of the Northern Hemisphere, traversing the Equator in Indonesia. During the 19th and early 20th centuries, many species and cultivars were planted as ornamentals in Europe, North America, and parts of the Southern Hemisphere, notably Australasia.

Wandlore
The unfounded belief that only pure-bloods can produce magic from elm wands was undoubtedly started by some elm wand owner seeking to prove his own blood credentials, for perfect matches between elm wands and Muggle-borns are known to exist. The truth is that elm wands prefer owners with presence, magical dexterity and a certain native dignity.

Of all wand woods, elm&mdash;in the experience of Garrick Ollivander&mdash;produces the fewest accidents, the least foolish errors, and the most elegant charms and spells; these are sophisticated wands, capable of highly advanced magic in the right hands (which, again, makes it highly desirable to those who espouse the pure-blood philosophy).
