Which cactus am I?

[LivistonaFan]

Hello,

Compared to palms I know even less about cacti (cactuses?). After some heavy rainfall yesterday I took this photo this morning:

 

I got this Cactus last year and always wanted to know which genus it belongs to. Now it is in flower and the experts should definitely be able to identify it. 

Here are some other photos of it and its offshots (you know what I mean):

Echinopsis oxygona, one of the most common of the "Easter Lily" Cacti. Given time, each specimen will offset to create bigger clusters and a lot more flowers. Offsets or "Pups" are easily separated ( if you don't want the clumps to get too big) once the size of an American Quarter.

Thank you. I knew it wasn't a special cactus. It's cold/ cool hardiness should be high considering its habitat? So it would be able to survive in a mediterrenean climate let's say in zone 9?

Because I don't spend much times with cacti I don't know their needs. Therefore I am just using three parts Basalt and one part regular garden soil as potting medium. Its very cheap and they seem to like it (It is very quick draining but holds also some moisture). But is it also recommendable long-term?

Yes, very easy in zone 9 ( very commonly seen in places with a Mediterranean-climate such as California, USA)  Echinopsis as a whole are generally one of the easiest cacti to cultivate. Most can take some cold though you don't want to expose them to frost or a freeze.

As long as it contains ingredients to help with drainage, they also handle a more organic- based soil medium better than other Cacti genera that can have very specific soil requirements.  The soil you are using should be fine though again, just be sure it doesn't stay too wet, especially when cooler. I myself will normally soak my own collection once or twice a month when its warm, less in the winter months. 

Cacti will only absorb so much water. Any extra is wasted or can cause problems like splitting, or rot.

Clumps of this easy to grow genus can end up looking like mine in bloom this year: http://www.palmtalk.org/forum/uploads/monthly_2018_05/Echinopsis-2018.png.272d578a5dd36d23482c7fdb3aff6a89.png and http://www.palmtalk.org/forum/uploads/monthly_2018_05/Echinopsis-Bloom-2018.png.59ca452ab57573bf9b8f6d2f8e1a3ff8.png
