If you enter search terms Sedum cyaneum, quite often you will see a link on which the picture is entirely different species, most pluricaule Sedum, Sedum ewersii sometimes. It is well known that the species of the genus Sedum are messed up and our diligent gardeners still support him. I think that there is nothing jednouduššího than you on the internet to verify that the advertised name or appearance agrees with the right plant. Well, perhaps it is still a problem for many. I would therefore like to address one such "Bermuda Triangle" which ineternetu on radio and in the following lines said all the right kinds of comparison míruvzájemným cyaneum Sedum, Sedum and Sedum pluricaule ewersii.

For starters, consider it important to note that Sedum is highly prized cyan Roštín, as well as specialist collections is rare and the market are normally sold. The confusion between these species was probably due to the color of their flowers, which is pink all three cases.
