When do long-day plants flower?

in the summer.








this is the key





there are LONG DAYS in the spring and summer.....therefore the plants are going to flower in the spring or summer





there are SHORT DAYS in the fall and winter......therefore that plants are going to flower in the fall or winter

FlowersBirthday FlowersSympathy FlowersMostly the terms long day and short day plants is confused due to their origin name. they were named like that because first it was thinked that flowering was sensed with day length but it is wrong. it is proven that flowering is sensed by the length of dark period (night) not by light period (day). so long day plants flower when night are long (winter) and short day plants flower when the nights are short (summer)yahoo finance
