We have experienced above average moisture and temperature. I find this fascinating and would like to share the following information with you. This is called photoperiodism. The alarm clock of each species is set at different intervals. It regulates growth, flowering, seed germination, dieback, dormancy, and the breaking of dormancy.
Daylight remains constant for corresponding dates each year.
If light or photoperiodism were the only factor influencing flowering time then each species would bloom on the same day year after year. But the parade of spring flora is not only influences by light, but also my factors such as temperature and moisture. This includes moisture received throughout the year and possibly from previous years as well. Sudden growth in spring requires food preserves. These are accumulated the year before and stored in underground parts such as roots, bulbs, corms or rhizomes.
