Light is a necessary condition for photosynthesis of flowers and plants. When there is sufficient light, photosynthesis is exuberant, organic nutrients are accumulated, plants grow and develop healthily, flowers blossom more and flowers are large. But to like the sun, neutral, shade-resistant flowers should be treated differently, such as rose, pomegranate and other sunny should meet the needs of the sun. Mountain flowers, azaleas and crab claw orchids should be shaded when they are exposed to strong light in summer, otherwise they will affect their flowering.

According to the number of hours that flowers like daylight, they can be divided into long-day, medium-day and short-day flowers. More than 12 hours of light a day in order to differentiate flower buds called long sunshine flowers. Such as white orchid, magnolia, magnolia and gladiolus thin, etc. Flowers in China and Japan are insensitive to light, and both long and short days can differentiate flower buds. Such as carnation, petunia and so on. Short-day flowers need less than 12 hours of sunshine every time they open, such as chrysanthemums, ivory red and so on.
