Allium elmendorfii is a species of wild onion endemic to Texas. It is known only from Bexar, Frio, Wilson, and Atascosa Counties. It is generally found on sandy soils,[2] specifically "well-drained sands, Eocene, Pleistocene and Holocene sands, and has only a 400 x 160 km range." Its habitat is "Forest/Woodland, Savanna, Woodland - Hardwood" and specifically "{g}rassland openings in post oak (Quercus stellata) woodlands on deep, well-drained sands derived from Queen City and similar Eocene formations."[1]
