Chrysanthemums are short-day plants. select conditions in which you expect chrysanthemums to flower.
SpyIntel [72]

Due to the information that they are short-day plants, I would expect chrysanthemums to flower during the times of the year when <u>days are shorter and nights are longer. </u>

Plants require sunlight to grow and flower or produce fruit. While some plants require more light than others, almost all plants require some form of light to survive, much less flower. Pants are often classified according to the amount of light that they require, these classifications are:

  1. Day-neutral plants
  2. Long-day plants
  3. Short-day plants

Day-neutral plants are those that can flower regardless of the amount of light that they receive. These are very resistant species of plants that can thrive even through periods of prolonged darkness. Though they do well with even a small amount of light, they will still require it to survive. One example of this kind of plant is the <em>tomato</em>.

Long-day plants are, as the name may suggest, plants who thrive when the days are longer. These plants will not survive or bloom without many hours of sunlight every day. The <u>optimal conditions for this kind of plant are meet during the summer,</u> when the Earth is tilted towards the sun, causing longer days.

Finally, short-day plants are those who require little sunlight to flower. These are different from day-neutral plants in that during days with many hours of sunlight, they will not flower. These plants, such as the chrysanthemums, will only flower if daylight hours are low, meaning that <em>spring</em> and <em>fall</em> are <u>optimal conditions for these plants to prosper. </u>
