Spring Grove Floral Phenology List
The purpose of this phenology list is to record the floral sequence of bloom as seen on the grounds of Spring Grove Cemetery and Arboretum. Each month is divided into three periods: Early month representing the 1st through the 9th day, Mid-month representing the 10th through the 19th and Late month representing the 21st through the end of the month. Cultivated varieties (Cultivars) of a species are generally grouped unless significant floral quality of the plant merits its mention. Also note that seasonal bloom is governed by Growing Degree Days (GDD) which can shift the bloom period based on temperature regimes.
