Phenology is the scientific study of nature’s seasonal events—when cherry trees bloom and when birds choose to nest, for example. Studying phenology is a great way of getting outside and observing nature. Longwood Gardens has been observing and collecting the phenological data of when plants boom in our Gardens for many years. The data collected helps predict when plants will bloom each year, when to collect pollen for breeding programs, when to photograph flowers, or to let guests know the best time to visit to see a specific bloom. We are lucky to have a team of 15 trained observers who are dedicated to this important task.
