The Echinopsis eyriesii is a fun and interesting species of the Echinopsis genus. It is a type of cactus that is easily identifiable by its ability to withstand cold temperatures and its large, night-blooming pink-white flowers. Due to its distinctive size and shape, sea urchin cactus is also frequently used in landscaping and is known as a night-blooming cactus.  If the weather is cool or cloudy, the flowers can stay open for two or more days.

Overall, this sea urchin cactus, Echinopsis eyriesii is an easy plant to care for and makes a great addition to any cacti collection! 

Watering Needs 

This sea urchin cactus plant can withstand droughts and doesn't need to be watered frequently to survive. In reality, Echinopsis cacti are acutely susceptible to overwatering and are vulnerable to root rot if overly wet. Between waterings, let the soil completely dry out, and if in doubt, give it a little more time before watering again.

Remember that cacti in the desert can go for weeks or even months without water, so water them sparingly during their rest phase and moderately during their active growing season. 

Light Requirements 

If you're looking to grow a healthy and thriving sea urchin cactus plant, you'll need to provide it with plenty of bright, indirect light. When grown as a houseplant, it should be placed in the sunniest spot in your home to receive the six to eight hours of bright sunlight that it needs each day.

This usually means placing your sea urchin cactus plant in a south or west-facing window or using a grow light to provide supplemental light. However, it may experience stunted growth, curled leaves, and faded colors, even though it can survive in low light.
