What are short-day and long-day plants?

CORVALLIS – It’s discouraging when your lettuce bolts or you can’t get your mum to bloom. There’s a reason for that, and it’s all about day length, which determines or how much light the plant gets. To understand plant flowering, you need to get a handle on “photoperiodism,” or amount of light and darkness a plant is exposed to. The amount of uninterrupted darkness is what determines the formation of flowers on most types of plants, according to Oregon State University Extension Service horticulture experts.
