This native of China, Tibet, Bhutan is planted in south flower bed of Azumaya, so one can see it well while looking at the orchard; it doesn’t seem to be a profuse bloomer, possibly because it was only planted only a few years ago.
There is a website called Paeonia Suffruticosa, which is dedicated to this shrub: […] Tree peonies can reach heights of between four and ten feet. Although the common name refers to the plant as a tree, it is actually classified as a woody shrub. A slim stem supports the sparse branches of the plant that are adorned by dark green foliage during the spring and summer and become bare in the autumn when leaves drop. Blossoms of the tree peony can almost dwarf the plant, extending up to 8” in diameter through the late spring and early summer of the year. […]
And here is an excellent page on tree peony from Missouri Botanical Garden: […] These long-lived plants usually take several years to establish, and are best left undisturbed once planted. Moreover, plant roots go deep and transplanting can be difficult. […] Hmm, I thought there was a plan to transplant this shrub, before it blocks orchard view, must ask Sue, the Senior Gardener.
