May I point you in the direction of The Sedum Society.http://www.cactus-mall.com/sedum/Lots of information about your favourite plants in there. And other members from the Czech Republic too.
Now here it is, nearly mid afternoon, and I'm supposed to be working today, but all that I have done is follow one plant-link after another, and the hours go by. After taking a quick peek at those two Czech sites, I'll need to come back to them tonight, armed with Bing Translator in my Firefox browser, for a couple hours of succulent treats Dagmar, that's a fine clump of Sempervivum 'Cmirals Yellow', one that isn't the easiest to grow well and have clump up; just look at all those offsets, yours is a very happy plant. Many web photos show plants grown under low light conditions so they don't color up as intense yellow as they should. Here's a Flickr photo of it that also comments about the difficulty keeping this plant happy, as well as showing intense foliar color.http://www.flickr.com/photos/donglos/3556136185/
