Kew Gardens is a leading centre of botanical research, a training ground for professional gardeners, and a popular visitor attraction. The gardens are mostly quite informal, with a few more formal areas. There are extensive conservatories, a herbarium, and a library.
Kew is important as a repository of seeds; it has one of the most important seedbanks. With the Harvard University Herbaria, and the Australian National Herbarium, they cooperate in the IPNI database to produce an authoritative source of information on the nomenclature of plants.
On 3 July 2003 the Royal Botanic Gardens, Kew was officially added tp the UNESCO list of World Heritage Sites.
