Filo · Accepted Answer

Short Day plants: A plant that requires a long period of darkness, is termed a "short day" (long night) plant. Short-day plants form flowers only when day length is less than about 12 hours. Many spring and fall flowering plants are short-day plants, including chrysanthemums, poinsettias, and Christmas cactus.
Long day plant: Long-day plants require less darkness to generate the reaction needed for production. These plants need about eight hours of darkness to start flowering. The long-day flowers that grow well in the home garden are lettuce (Lactuca sativa), spinach (Spinacia oleracea) and petunias (Petunia x hybrids).
