In addition to catalogs from commercial horticultural businesses, the Ethel Zoe Bailey
Horticultural Catalog Collection contains seed listings from botanical gardens around the world.
Botanists use these lists for a variety of research endeavors. Those studying a
particular group of plants grow out varieties within the group in order to study
their characteristics. In addition, herbariums, such as Cornell's Wiegand Herbarium,
grow out specimens from botanical gardens to fill out their collections, while
researchers engaged in plant breeding experiments may look to botanical garden
listings as a source of material.
