As the century drew to a close, the references became fewer and fewer. When the old growers died, the desire for large collections of Chinese tree peonies apparently died with thep:l. The varieties they had grown with the possible exception of P. papaveracea had full double flowers. They were so heavy that the stems could not properly support them, with the result that many of the flowers were hidden under the foliage.
