Botanical gardens grow a wide variety of plants both for scientific purposes and for the enjoyment and education of visitors.
The scientific work done at botanical gardens includes studies of how to adapt exotic plants to grow in the locale of the garden; taxonomic studies; and the propagation of rare or endangered species of plant. Kew Gardens, near London, has been publishing a scientific journal of botanical research, illustrated in color, since the late 18th century.
Educational projects range from introductions to plants that thrive in different environments to practical advice for the home gardener. Many botanical gardens have plant shops, selling flowers, herbs, and vegetable seedlings suitable for transplantation.
