Making global impacts.
The peony garden is an unrivaled, unique, contemporary and long-term research structure on the world stage. There are three reasons for this.
1.
Since its foundation in 1922, our garden has grown the cultivars in pairs – biological replicates. Cultivars are (usually) cloned from the same mother plant even though they may be greatly multiplied in numbers and dispersed across the world. Like identical twins, they should have very similar characteristics – both in how they look (phenotypes) and how they respond to any given interaction with the world (based on their genotypes.)
2.
Our specimens have not been regularly fertilized or sprayed to control pests since at least the 1930s. Thus what we see are the inherent responses of the plant’s genomes at this site. In addition, our plants are only rarely divided and we know the years since being divided. As a result, we can tease out ‘age’ since being vegetatively rejuvenated.
3.
Ours is an historic collection – a significant living archive. Most ornamental reference collections make some effort to keep up with the times, and being limited in space, remove less-popular specimens to make way for the new. Ours is a time capsule from the first introduction of these floral gems from China and Japan and through the peak of development for floral fragrances.
Areas of
focus
Our current focal areas of work (the three points below) were formally structured in 2015.
That is the year the University of Michigan and the Central Botanical Garden – Minsk of the National Academy of Sciences, Belarus signed a formal Memorandum of Understanding to further research projects of mutual interest.
This agreement has been renewed, and is the basis of the research reported below – and in progress through mutual funding.

History of Herbaceous
Peony Domestication
The history of herbaceous peony domestication and cultivar breeding has been intractable for over two centuries. Shifting social agendas of the breeding programs as well as the emergence and spread of bacterial, fungal and viral diseases has left unresolved several key questions, as:
Which peonies are related to which, and how closely related are they?
Research
projects
There are additional research projects that have emerged from our work. We have work in progress in addition to the public information and research presentations and publications listed below.
Since 2014, funding for this deepening research has been supported by the Belarusian Foundation for Fundamental Research, MCubed, and the W. E. Upjohn Peony Garden Fund. In addition, specific further-partnered research projects (cited below) have additional funding sources. In addition, specific student projects have been funded by generous donors.
As we implement our research trajectory, and now that we have a robust data-management model, we will be seeking more significant funding related to our plant/virus work that is based on a genomics-based framework of the cultivar-relationships. With this, we can expand to include additional institutional partners in the Plant Collections Network of AGPA, and beyond.
UM Student Research and Internship Projects
UM students, faculty, curators and colleagues at the CBG-Minsk, NAS Belarus, with additional partners as needed, have an ongoing set of research projects. These outputs are listed in reverse chronological order – newest first.
