Echeveria 'Rainbow' is a variegated form of Echeveria 'Perle Von Nürnberg'. It is a colorful, rosette forming succulent, changing in color.
Echeveria amoena - must see reference for beginning succulent gardens with names and photos and info of all the varieties of succulent! Fantastic website! I got a variety pot of succulent as a gift and this helped identify each one and care for them better.
