Wolf’s cholla (“cholla” means a cylindrical stem) is native to extreme southern California and part of the Baja peninsula. Identification: These heavily branched, shrublike plants reach 20-59" (50-150 cm) in height. Stems are segmented, yellowish green, with segments 2-16" (6-40 cm) long and ⅞-1½" (2.5-4 cm) around. Spines are yellowish to brown, darkening with age, in groups of 12-30, up to 1" (3 cm) long. Flowers are yellowish green with tinges of bronze, to purplish brown. (Thanks to Joanne Schwartz for correcting an error in my reporting of flower color.) Grayish fruits are densely covered with spines, about 1" (3 cm) long and 1" (3 cm) in diameter. References:
