Received as a grafted plant under the name Prunus serrulata 'Wase-Miyako'. Prior source: Glenn Dale. [For possible earliest introduction of this cultivar to U.S., see PI-45060, a tree imported by David Fairchild from Yokohama Nursery Co. in 1905, donated to USDA in 1917. Kingsville Nurseries offered the plant as early as 1928, when it was listed in its wholesale trade list as 'Wasemiyuki'; the nursery started in 1921, and PI 45060 was recorded growing at the Yarrow Plant Introduction Field Station in Rockville, Maryland at the time it was numbered in 1917. It may have been transferred to Glenn Dale shortly thereafter when the station was abandoned and Glenn Dale established (1919), and then acquired by Kingsville before 1928. The prior history beyond Glenn Dale is presumed based upon this information and timeline. -SBL] From USDA Plant Inventory no. 52: "45049 to 45064. Prunus spp. Amygdalaceae. Japanese flowering cherry. Grown at the Plant Introduction Field Station, Rockville, Md., from scions presented by Mr. David Fairchild from his place, "In the Woods," Chevy Chase, Md. The collection came originally from the Yokohama Nursery Co., of Japan, in 1905. Numbered August 27, 1917. Quoted notes by Mr. Fairchild. If anyone would grow these lovely flowering trees, he should be prepared to protect them from the San Jose scale by spraying them every spring before they flower (February or March) with the lime-sulphur solution. [...] 45054 to 45062. Prunus serrulata Lindl. [...] [45060. "Variety _Wasemiyako_. Large, semidouble, almost pure white flowers, upright on short stems, very attractively arranged on the branches. Midseason (Apr. 20 in Maryland). Tree only fairly vigorous. Suitable for lawn planting, and showy from a distance." [Further note: Although the original material of this accession was received grafted onto rootstock, all subsequent propagations were made by rooting cuttings; the surviving plant is growing on its own roots. -SBL] | 2192790 | PI 45060 NA 23907 |

Jefferson referenced on card (letter not yet located in Plant Records). Hybrid of P. serrulata [probably a Sato-zakura, or possibly P. speciosa -SBL] and P. campanulata. Scions sent to Hess Nurs. for custom grafting in February 1973. [This is likely the clone that was introduced later as 'Pink Cloud' by Huntington Botanical Gardens. It may be the correct identity for NA 74709-H growing in the triangle meadow of the Prunus Collection, as this was last recorded growing in that area in 1992 with no further updates on the accession card. (Further update: a handwritten note about an unknown cherry in the triangle by Roland Jefferson confirms that he knew it to be the tree that they had received from Huntington; the tree also matches the Huntington Botanical Gardens' description of 'Pink Cloud' well, although it seems to be more vigorous in the DC climate. -SBL) Unfortunately, the name 'Pink Cloud' is technically invalid, as it is superceded by Prunus x subhirtella 'Pink Cloud' (see U.S. Patent 4,540), which has statutory registration authority acceptance and probably priority. Another very similarly named cultivar, Prunus campanulata 'Pink Clouds' (selected by Mark Jury of New Zealand) is also not to be confused with this; its name is questionably acceptable due to its similarity and lack of priority. For propagations of this accession that were formerly recorded as NA 74709.01, see 34928.01. Received as Prunus hyb. (serrulata x campanulata). | 2142872 | NA 34928 |

Slope: 5 to 8 percent. Aspect: N/A. The underlying geology of this area is characterized as Citronelle Formation of the Pliocene period. The Citronelle Formation is widespread in the Gulf Coastal Plain. The type section for the Citronelle Formation, named by Matson (1916), is near Citronelle, Alabama. The Citronelle Formation grades laterally, through a broad facies transition, into the Miccosukee Formation of the eastern Florida panhandle. Coe (1979) investigated the Citronelle Formation in portions of the western Florida panhandle. The Citronelle Formation is a siliciclastic, deltaic deposit that is lithologically similar to, and time equivalent with, the Cypresshead Formation and, at least in part, the Long Key Formation (Cunningham et al., 1998) of the peninsula. In the western panhandle, some of the sediments mapped as Citronelle Formation may be reworked Citronelle. The lithologies are the same and there are few fossils present to document a possible younger age. The Citronelle Formation consists of gray to orange, often mottled, unconsolidated to poorly consolidated, very fine to very coarse, poorly sorted, clean to clayey sands. It contains significant amounts of clay, silt and gravel which may occur as beds and lenses and may vary considerably over short distances. Limonite nodules and limonite-cemented beds are common. Marine fossils are rare but fossil pollen, plant remains and occasional vertebrates are found. Much of the Citronelle Formation is highly permeable. It forms the Sand and Gravel Aquifer of the surficial aquifer system contain organics. The dominant fossils in the freshwater carbonates are mollusks. (Source: USGS Florida Geologic Map Data). The surface soil profile is classified as Troup-Orangeburg-Cowarts complex, 5 to 12 percent slopes. The Troup series consists of very deep, somewhat excessively drained soils formed in unconsolidated sandy and loamy marine sediments. Troup soils are found on ridges and hillslopes. The Orangeburg series consists of very deep, well drained, moderately permeable soils on uplands of the Southern Coastal Plain. They formed in loamy and clayey marine sediments. The Cowarts series consists of very deep, moderately well and well drained soils on ridge tops and side slopes on uplands of the Coastal Plain Major Land Resource Area. They formed in loamy marine sediments. The reaction of all these soils ranges from very strongly acid to strongly acid.
