Origin of Name
Echinopsis sp. cv. 'CHOCOLATE' (forma monstruosa cristata) is a cultivar name that vividly describes this unique cactus. The genus 'Echinopsis' is derived from Greek, meaning 'hedgehog-like', referring to the spiny appearance. The name 'CHOCOLATE' reflects the rich, dark coloration of the cactus, while 'monstruosa cristata' indicates the plant's growth form. 'Monstruosa' refers to the abnormal, mutated growth pattern, and 'cristata' denotes the crested form, where the cactus grows in a wavy, fan-like structure instead of the typical cylindrical shape.

Technical Description of Plant
This Echinopsis cultivar is characterized by its unusual crested growth pattern, presenting a striking, sculptural form. The 'CHOCOLATE' variety is particularly noted for its rich, dark brown to chocolate-colored, velvety-looking skin. The cresting results in a convoluted, undulating structure, with the plant often forming multiple crests. Despite its monstrous form, it may occasionally produce the genus's typical large, colorful flowers.

Origin of Plant
Echinopsis is a genus native to South America, primarily found in regions with arid climates. The 'CHOCOLATE' (forma monstruosa cristata) cultivar, however, is a product of selective breeding and does not occur naturally in the wild.

Conservation Status
As a cultivated variety, Echinopsis sp. cv. 'CHOCOLATE' (forma monstruosa cristata) does not have a specific conservation status and is not listed as endangered or vulnerable.

Care instructions
This cactus requires well-draining soil and a pot with good drainage to avoid root rot. It thrives in full sun to partial shade and should be watered moderately when the soil is dry to the touch. In winter, reduce watering to prevent waterlogging. The plant is not frost-tolerant and should be protected from freezing temperatures. Fertilize lightly during the growing season to support healthy growth. Due to its unique form, handle it with care to avoid damaging the crested areas. Regular inspection for pests and diseases will help maintain the health and striking appearance of this distinctive cactus.
