The study was done by researchers at The University of Texas Health Science Center at Houston, the University of Miami and The University at Albany.
The researchers looked at the health effects of peonies and other flowering plants.
They found that the peonies were more than 30 percent healthier than when they were planted when they had been in bloom for less than a decade.
The study also found that they were more likely to be healthy than when the plants were planted in the wild, according to the study.
The researchers say the findings should not be taken to mean that the plants are more healthy than in their native environments.
Researchers say that the results were not statistically significant, but it is an important study to learn more about the health benefits of plants and their environments.
