Bloom Date Project
This Bloom Date Project is an attempt to clarify what we know and more importantly, do not know about the blooming pattern of peonies. This is a long run project to which I hope many will contribute.
For the peony buyer, it would be better if nurseries had a common bloom period classification system. Currently, buyers will find the same cultivar classified as mid season in one catalogue and early in another. This problem carries over to peony books. If the author gathered information about bloom time from a number of sources, it is very likely that the different sources use different classification systems.
By collecting data over a long period of time and in several different locations, this project attempts to make available the information required to put in place a common bloom period classification system.
