Stretching refers to stretching towards the light source, with the most ultraviolet rays e.g the sun. The cells in the stem constrict as it does when it grows or called ettiliation.this will not hurt the succulent but when it commences new growth the ettiliated spot is permanent u will always be able to tell. This plant is good at cloning so study up on it and u can have numerous pearlys from just one parent plant. Hope this helps, Bark.RosemarieRo wrote:It is Echeveria 'Perle von Nurnberg'.
