Etiolation

Spanish bluebells Hyacinthoides hispanica, showing both leaves and flowers in both etiolated and non-etiolated states. The longest etiolated leaves are about 50 cm long

Etiolation /iːtiəˈleɪʃən/ is a process in flowering plants grown in partial or complete absence of light.[1] It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color (chlorosis). The development of seedlings in the dark is known as "skotomorphogenesis" and leads to etiolated seedlings.
