Hello again,
the cactus grows a lot of huge flowers since some weeks. Here is a nice picture of one. Since the flower is yellow I'd exclude trichocereus. Anyone any idea?

Again, thanks a lot. However, I am confused (as probably most beginners are) by the names. I thought that Trichocereus peruvianus, Cereus peruvianus and Echinopsis peruviana were the same plant. Obviously I was wrong :-k I tried to find distinct features and here is what I got: The flower should be ...

Thanks a lot for your help :D I've been told that they might sell it. Even though I would like some larger cacti, this one is HUGE!

Homepage (in German): http://winter-kaktus.de I translated the most important facts: The following cacti can be grown outdoors in Germany (up to -20° Cels...

Thank you for your replies.
Maybe it helps, that both cactie don't have any wool?

Hello, I'm new, so please excuse that I ask for an ID of one of the top ten. I have two specimen I think might be pilosocereus pachycladus, but I am unsure. Could you help me, please? Here is the data: 1st one: Height: 8 cm Diameter: 3 cm Ribs: 6 Areoles: ocher, about 1 cm evenly apart Spikes: gold,...
