Echinopsis eyriesii is native to Southern Brazil, Uruguay, and Entre Ríos Province, Argentina. It grows in lowland habitats up to 1,000 meters above sea level. In these areas, the climate is tropical and continental, where typically, winters are dry, and summers are rainy. The precipitation reaches 1500 mm a year with an average annual temperature of 25–30°C. Rarely the temperature drop below zero degrees.[1]

Description
E. eyriesii is a large caespitose cactus known for its large nocturnal flowers. It is among the most commonly grown globular cacti.
E. eyriseii is globular, elongated, and approximately cylindrical. It typically grows to 15–30 cm high and 12–15 cm thick. In favorable conditions, E. eyriseii may form mounds up to 1.5 m tall and 2–3 m wide. The cactus is dark green and has 9 to 18 ribs, which have circular areoles with 10 to 18 spines each.
Echinopsis eyriesii var.cristata is instead Fan shaped but still has all the other characters of E. eyriseii[3]
Its floral stem develops over the course of a month up to 20 cm long. The flowers bloom in the evening of either spring or summer. The flower usually blooms for a day, but may last longer in cold or rainy conditions.[1]
Echinopsis eyriesii var. inermis, or Echinopsis inermis, is a spineless variety.[4]
Cultivation
Echinopsis eyriesii is widely grown for the huge nocturnal flowers. It needs fertile and well-drained soil with sunlight to grow. It can be grown outdoors year-round in frost-free climates, in a pot or in the ground. It should be watered in summer, but the soil should dry between waterings. The cactus should not be watered in winter so that the flowers bloom. The cultivation temperature may be as low as −7°C. [1]
