Etiolation is the stretching of a plant which has been deprived of sufficient sunlight.

Both of these plants were purchased together and divided 6 months ago.  The first plant has been living in my patio and gets a lot of direct sunlight from dawn till sunset.  The second plant has been living in my boyfriend’s balcony which gets a few hours of sun light.  Notice the difference in color and style of growth.  The first echeveria is a bright green.  It has stayed short but popped out two babies on each side.  The etiolated echeveria has pale chalky leaves and has stretched out, growing upward.
