Taxonomy ID: 1456
Cereus hildmannianus, commonly known as the Hedge Cactus or Peruvian Apple Cactus, is a species of cactus from southern South America. Its distribution is uncertain but probably includes Brazil, Paraguay, Uruguay and Argentina, and the plant has become an invasive species in other countries. It is an attractive, treelike cactus that grows like a candelabrum with numerous columnar branches reaching 5-10(-15) m in height with distinct trunks. It produces white flowers that are 10-15 cm across, followed by goose-egg-size succulent fruits containing delicately sweet white pulp with crunchy black seeds. Furthermore, its stems are free of spines, allowing for easy handling without impalement. As a houseplant, it is popular and easy to care for - requiring direct light and little water to thrive. Two subspecies are recognized.
