When do short-day plants flower?

typically in the fall.

FlowersBirthday FlowersSympathy FlowersA short day plant is a plant that cannot flower under the long days of summer. Short day plants typically flower in the fall of the year. These plants require a certain number of hours of darkness in each 24 hour period (a short daylength) before floral development can begin. Plants use the phytochrome system to sense daylength or photoperiod.
