Gold Medal Plant Award Program sponsored by the Pennsylvania Horticultural Society this program recognizes "trees, shrubs, and woody vines of outstanding merit" and are recommended for USDA Zones 5-7 and is a good place to look when considering adding shrubs and trees to the home garden.
The United States Department of Agriculture (USDA) is an executive department of the United States federal government that aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally.
It is a unique resource documenting new introductions of fruit and nut cultivars as well as specimens discovered by USDA's plant explorers, representing 38 plant families in all. [20] Some of these watercolors were published in the Yearbook of the United States Department of Agriculture in the 1902–1913 period, but many were never published ...
Since the establishment of the Office of Seed and Plant Introduction there has been an office within the USDA with this responsibility, though its name changes periodically. [2] Today, the branch of the USDA responsible for collecting and introducing new plant species is called the National Germplasm Resources Laboratory. [2] [7]
Transplants are rarely successful, and the development of mature plants from spores is very slow (taking perhaps 20 years). They can be grown with frequent application of weak fertilizer solution under bright light, high humidity, and year-round moderate temperatures in greenhouses, growth chambers, and laboratories.

The flowers are white, yellow or red, 2–6 cm (1–2 in) diameter with 6–9 petals, and mature ...
The U.S. National Plant Germplasm System (NPGS) is a network of institutions and agencies (federal, state and private) led by the Agricultural Research Service (ARS) of the U.S. Department of Agriculture in the effort to conserve and facilitate the use of the genetic diversity of agriculturally important plants and their wild relatives.
