In forest gaps, individuals have red bracts, whereas the bracts remain green in individuals growing in forest shade. Bract colouration is a phenotypically plastic trait because individuals can sport both colour phenotypes if they receive direct sunlight on only one side. Red colouration often develops in plant tissue as a protection against excess sun light.
