We believe that echeveria can be classified in three different size categories. Small: echeveria lola, echeveria decora,echeveria glauca, echeveria harmsii, echeveria violet queen, medium: echeveria agavoides, echeveria black knight,echeveria blue sky, echeveria imbricata, echeveria perle von nernberg, echeveria subsessilis, or large: echeveria blue curls, echeveria etna, echeveria mauna loa, and echeveria subrigida. Of course, within these three classifications, there will be variance between the plants, but its a good general rule. Always take into consideration the application of the plant, or it’s size. The larger echeveria can be used as a single, focal point, in a lower succulent garden, or the larger echeveria can be used as accents to even larger plants (aloe bainseii) in a larger garden. The same plant can have many different applications.
