I have been waiting for a few cacti to bloom for the first time this year. One of them was Echinopsis that I grew from seed. It is 6 years old already and didn't bloom a single time. Last year it started

I heard somewhere that this cactus does not (or is very hard to) propagate though seeds and the only way is the cuttings. Thus all the plants grown in home conditions come from the ones grown in a wild.
