Habitat
Echinopsis oxygona, 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 and 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.[1]
Cultivation
Echinopsis oxygona is known for having huge, showy flowers at the ends of long tubes which are connected to the cactus. The flower has a sweet smell. The flower opens in the evening and wilts the next afternoon on hot days. It grows well in full sun, or light shade. These cacti can stand strong heat, and even temperatures as low as Шаблон:Convert. Usually these are outdoor plants. They are used to the dry, desert climate, so they do not need to be watered every day.Шаблон:Fact
In the 19th century, Echinopsis oxygona was extensively hybridized with other Echinopsis and Lobivia species, giving rise to a number of cultivars.[1]
In cultivation in the UK this plant has received the Royal Horticultural Society's Award of Garden Merit.[2]
Propagation
On cool days it will last longer.Шаблон:Citation needed Usually, the cactus will start to have small offsets appear at its base. These can be plucked off and transplanted into a different pot for further growth into a mature cactus. Usually, the cactus will bloom in mid summer.
