Huisachillo is commonly considered a shrubby version of Huisache. It has a broad range, found from southern Texas and southern Florida in the north, down through the Caribbean, Mexico, and Central America to northern South America. In Texas, it is found on limestone soils in the Rio Grande Plains, where it can grow into a tree of 15 to 20 feet, and on the southern edge of the Edwards Plateau. Huisachillo tolerates more cold than the taller Huisache. Its seed pod is 21/2 to 3 long and is covered with downy hairs, while that of Huisache is glabrous, shorter, and much more woody and rounded.
