About this plant
Echinopsis is a genus of cacti known for their round, ribbed bodies and large, showy flowers that often bloom at night. They are popular as ornamental plants due to their striking blooms and easy care. These cacti store water in their thick stems, making them drought-tolerant and suitable for indoor or outdoor growing in warm climates.
