Short-day plants flower when the night lengths exceed their critical photoperiod. They cannot flower under short nights or if a pulse of artificial light is shone on the plant for several minutes during the night; they require a continuous period of darkness before floral development can begin. Natural night time light, such as moonlight or lightning, is not of sufficient brightness or duration to interrupt flowering.
