Location: Floral and Nursery Plants Research Unit
2012 Annual Report
Data collected will include the location of the plant, the provenance of the germplasm (when known), significant characters that may not be permanently preserved with the specimen (such as growth form, odor, color of flowers and fruit). Brief notes may also be made of any evidence noted of spontaneous reproduction in the vicinity of the planting, of heavy damage that might be caused by disease, insects, or abiotic factors, and any other available data that may provide insight into the biology or ornamental value of the plants in the site.
The University of Washington PI will identify an appropriate collector or collectors to carry out the collecting. The collector(s) will be trained in techniques for collecting herbarium specimens and supervised by the University of Washington PI. Unmounted herbarium specimens with the data recorded on appropriate, archival-quality labels will be supplied to the herbaria: one complete set to the University of Washington Herbarium, and one complete set plus exchange sets to the herbaium of the U.S. National Arbortum.
Once labeling and processing of the specimens has been completed, all material due to the National Arboretum from this SCA will be forwarded to the National Arboretum. One specimen of each species will be deposited in the herbarium of the National Arboretum, where it will be used for research on cultivated plants grown in the Pacific Northwest of the United States. An additional set of specimens is being deposited in the Otis Douglas Hyde Horticultural Herbarium at the University of Washington Botanic Gardens Center for Urban Horticulture, where it will support their research on ornamental plants of the Pacific Northwest. Duplicates will be exchanged with other collaborating institutions, strengthening National Arboretum collaborations with other institutions and bringing in herbarium material of additional species via the exchange.
