== Habitat == |
|||
''Echinopsis eyriesii'', native to Southern Brazil, [[Uruguay]], and [[Entre Ríos Province]], [[Argentina]], thrives in lowland environments, reaching altitudes of up to 1,000 meters above sea level. In these areas, there is a [[tropical climate|tropical]] and [[Continental climate|continental]] climate, characterized by arid winters and humid summers. The annual precipitation in these regions amounts to approximately 1,500 mm, sustaining an average annual temperature range of 25–30°C, rarely dropping below zero degrees.<ref name="llifle">{{Cite web | url=http://www.llifle.com/Encyclopedia/CACTI/Family/Cactaceae/8004/Echinopsis_eyriesii |title = Echinopsis eyriesii}}</ref> |

[[File:Echinopsis eyriesii.JPG|thumb|left|Flower of ''E. eyriseii'' in full bloom]] |
|||
''E. eyriseii'', characterized by a [[Glossary_of_botanical_terms#globose|globular]], elongated, and approximately cylindrical form, typically grows heights of 15–30 cm and a thickness of 12–15 cm. Under favorable conditions, it may form mounds up to 1.5 m tall and 2–3 m wide. The cactus displays a dark green hue and has 9 to 18 ribs, each having circular areoles with 10 to 18 spines.<ref name="llifle" /> |
|||
''Echinopsis eyriesii var. cristata'' is instead fan-shaped while retaining all the other characteristics of ''E. eyriseii''<ref name = varcris>{{Cite web|url=http://www.llifle.com/Encyclopedia/CACTI/Family/Cactaceae/25315/Echinopsis_eyriesii_var._cristata|title = Echinopsis eyriesii var. Cristata}}</ref> During its growth cycle, its floral stem develops up to 20 cm long over the course of a month. The flowers bloom in the evening of either spring or summer. Each flower usually blooms for a day, though may last longer in cold or rainy conditions.<ref name="varcris" /> |
|||
''Echinopsis eyriesii var. inermis'', or ''Echinopsis inermis'', is a spineless variety.<ref>{{Cite web|url=http://www.llifle.com/Encyclopedia/CACTI/Family/Cactaceae/25318/Echinopsis_eyriesii_var._inermis|title = Echinopsis eyriesii var. Inermis}}</ref> |

== Cultivation == |
|||
''Echinopsis eyriesii'', widely known for its [[caespitose]] growth habit and its impressive nocturnal blooms, making it one of the most commonly cultivated [[Glossary_of_botanical_terms#globose|globular]] cacti. |
|||
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. <ref name="llifle" /> |
|||
In the 19th century, Echinopsis eyriesii was extensively hybridized with other ''[[Echinopsis]]'' and ''[[Lobivia]]'' species, giving rise to a number of [[cultivars]].<ref name="llifle">{{Cite web | url=http://www.llifle.com/Encyclopedia/CACTI/Family/Cactaceae/8004/Echinopsis_eyriesii |title = Echinopsis eyriesii}}</ref> |
