Echinopsis cactus plants - but not too sure what variety they are. *

 

 I have a bunch of echinopsis cactus plants but not too sure what variety they are. Echinopsis is a type of cactus plant originating from South America. Can be found in these countries Argentina, Chile, Bolivia, Peru, Brazil, Ecuador, Paraguay and Uruguay).

These cactus plants are also known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. I have many in my greenhouse but not too sure which particular name can be assign to them.
