The flowers are excellent for cutting. It has dark green foliage throughout the season. The compound leaves do not develop any appreciable fall color. The fruit is not ornamentally significant. Landscape Attributes Rock's Tree Peony is a multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage. This is a relatively low maintenance shrub, and should not require much pruning, except when necessary, such as to remove dieback. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics. Rock's Tree Peony is recommended for the following landscape applications; - Accent - Mass Planting - General Garden Use Planting & Growing Rock's Tree Peony will grow to be about 4 feet tall at maturity, with a spread of 4 feet. It has a low canopy. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 20 years. 361 N. Hunter Highway Drums, PA 18222 (570) 788-4181 www.beechwood-gardens.com This shrub does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates.

Development of Ovule and Embryo Sac in Blotched Tree Peony (Paeonia Rockii)
Bull. Fac. Life Env. Sci. Shimane Univ., 4 : 13-20, December 20 1999 Development of Ovule and Embryo Sac in Blotched Tree Peony (Paeonia rockii) Fang-yun Cheng and Noriaki AOKI ' Abstract This paper dealt with the ovule ontogenesis and development, the megasporogenesis and the embryo sac development in Paeonia rockii cvs. The ovule, originated from the tri-zonate primordium, was anatropous, bitegmic and crassinucellate. And the nucellus consisted of different cytohistologrcal zones and differentiated by a particular way in which the derivative cells from both parietal and sporogeneous cells were contributed to the nucellar tissue. During the megasporogenesis and before the 4-nuclear embryo sac, the megasporocytes successively entered meiosis or commenced to degenerate. Generally a linear tetrad formed after meiosis and the chalazal megaspore was functional and developed into embryo sac by Polygonum type. Multicelled archesporium and multiple megas- porocytes in an ovule resulted in 1-3 embryo sacs, which developed to mature within several days after anthesis. Belated mature of embryo sacs supplies a device to guarantee the cross-pollination.

Received: 4 November 2017; Accepted: 4 December 2017; Published: 8 December 2017 Abstract: Paeonia qiui is a wild species of tree peony. P. qiui has good ornamental value owing to its leaf color change in spring. So far, the molecular mechanism of leaf color change in P. qiui is unclear. This study analyzes the anthocyanin level and transcriptome of two different color stages in P. qiui leaf. The purplish-red leaf stage is rich in anthocyanin, while the green leaf has very low levels of anthocyanin. Transcriptome analysis reveals that 6678 differentially-expressed genes (DEGs) are up-regulated, and 14,667 are down-regulated in the purplish-red leaf. Among these DEGs, 40 MYB (v-myb avian myeloblastosis viral oncogene homolog) genes, 40 bHLH (MYC-like basic helix–loop–helix) genes, and 15 WD40 (WD-repeat protein) genes were found. Based on phylogenetic and alignment analysis with the deduced amino acid sequences with known transcription factors, Unigene0024459 (MYB1) is likely the R2R3-MYB that promotes anthocyanin biosynthesis; Unigene0050761 (MYB2) is likely the R2R3-MYB that represses anthocyanin biosynthesis; Unigene0005081 (bHLH1) and Unigene0006146 (WD40-1) are likely the bHLH and WD40 that participate in regulating anthocyanin biosynthesis.

The Woodies-Part I
The Woodies-Part I Woody Paeonia Species -Nate Bremer- ____________________________________________________ This article and others were a part of a series about woody peonies which recently appeared in the American Peony Society’s Bulletin. This article does not include images that were printed with the edited feature articles. For complete articles with images, please become a member of the American Peony Society for published version access. My aim was to present a series of articles focusing on the major groups of woodies in cultivation that may help others grow this uniquely beautiful group of plants. After growing this unusual group of plants intensely for more than 15 years, I’ve learned much that may be of interest to others wishing to incorporate these wonderful plants into their collections. For the most part, information will be practical, rather than highly scientific. We grow all of our plants outside, without protection, in our USDA Zone 4 gardens and propagation fields. Thus the observations and information that follows may or may not be entirely applicable to all growing situations, but should serve as a good baseline for those that grow or would like to grow ‘woodies’. The species, or plants that occur in the wild are rare in their natural habitats and seldom seen in American gardens for a number of reasons. All originate from east Asian mountainous regions (mostly China) and have somewhat more demanding requirements to grow successfully. Some are not able to withstand our cold winters and others struggle with the excess water in our region at various times throughout the year.

The Woodies-Part III…Paeonia Rockii and Hybrids
The Woodies-Part 3 Paeonia rockii and Hybrids -Nate Bremer- This article and others were a part of a series about woody peonies which recently appeared in the American Peony Society’s Bulletin. This article does not include images that were printed with the edited feature articles. For complete articles with images, please become a member of the American Peony Society for published version access. The species, Paeonia rockii, was discussed in the first article in this series about woody peonies. Here we’ll take a look at the hybrids that were derived from P. rockii. Paeonia rockii was introduced to Europe and the United States through seeds collected by Joseph Rock in 1925, a plant collector for the Arnold Arboretum. The seeds collected by Rock at the Choni Lamasery were not actually the species P. rockii, but rather a hybrid with an unknown P. suffruticosa cultivar or seedling. For nearly 75 years the seeds grown from Rock’s peony were presumed to be the species, but recent advances in genetic markers and the identification of the true species in the wild have brought light to what Rock actually found. Seeds were distributed to a number of botanic gardens, plant enthusiasts, hybridizers and taxonomists in 1927. A good number of these seeds produced plants that were grown and bloomed successfully. These seed grown plants from the collection by Rock are commonly called ‘Rock’s Variety’, ‘Joseph Rock’ and all too often P. rockii (incorrectly). There is a U.S. form and U.K. forms that have been used extensively in hybridizing and are widely distributed.

E. ulmoides ‘Huazhong No. 12’ (H12) is the only red-leaf genotype of this species. In this study, the pigment contents of H12 and E. ulmoides ‘Huazhong No. 11’ (H11, green leaves) were determined. The differential metabolites in H12 and H11 were detected by UPLC-MS/MS, and the differentially expressed genes were screened by transcriptome. Then the key metabolites and corresponding gene regulation in anthocyanin related metabolic pathway were analyzed. Results: The chlorophyll a, chlorophyll b and carotenoid contents in H12 leaves were lower than H11, while the total anthocyanin content in H12 was 4.06 times higher than in H11. There were 96 up-regulated metabolites in H12, including anthocyanin, proanthocyanidins, avonoid and avonol. Among them, four differentially expressed anthocyanins were identied.

Genetic Structure of the Tree Peony (Paeonia rockii) and the Qinling Mountains as a Geographic Barrier Driving the Fragmentation of a Large Population Jun–hui Yuan1,3,4, Fang–Yun Cheng1,2*, Shi–Liang Zhou3* 1 Landscape Architecture College of Beijing Forestry University, Haidian District, Beijing, China, 2 National Flower Engineering Research Center, Key Laboratory for the Genetic and Breeding of Forestry Trees and Ornamental Plants, Beijing, China, 3 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, the Chinese Academy of Sciences, Haidian District, Beijing, China, 4 Gansu Forestry Technological College, Tianshui, Gansu, China Abstract Background: Tree peonies are great ornamental plants associated with a rich ethnobotanical history in Chinese culture and have recently been used as an evolutionary model. The Qinling Mountains represent a significant geographic barrier in Asia, dividing mainland China into northern (temperate) and southern (semi–tropical) regions; however, their flora has not been well analyzed. In this study, the genetic differentiation and genetic structure of Paeonia rockii and the role of the Qinling Mountains as a barrier that has driven intraspecific fragmentation were evaluated using 14 microsatellite markers. Methodology/Principal Findings: Twenty wild populations were sampled from the distributional range of P. rockii. Significant population differentiation was suggested (FST value of 0.302). Moderate genetic diversity at the population level (HS of 0.516) and high population diversity at the species level (HT of 0.749) were detected. Significant excess homozygosity (FIS of 0.076) and recent population bottlenecks were detected in three populations.
