Most young leaves pale in comparison to mature leaves: delayed greening is neither binary nor tropical

open access: yesEcography, EarlyView.
Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.
