Editing Botanical garden (section)

==== Community engagement ====

The second half of the 20th century saw increasingly sophisticated educational, visitor service, and interpretation services. Botanical gardens started to cater for many interests and their displays reflected this, often including botanical exhibits on themes of [[evolution]], [[ecology]] or [[Taxonomy (biology)|taxonomy]], horticultural displays of attractive [[flowerbed]]s and [[herbaceous border]]s, plants from different parts of the world, special collections of plant groups such as [[bamboo]]s or [[rose]]s, and specialist glasshouse collections such as tropical plants, [[alpine plant]]s, [[cactus|cacti]] and [[Orchidaceae|orchids]], as well as the traditional herb gardens and medicinal plants. Specialised gardens like the [[Palmengarten]] in [[Frankfurt]], Germany (1869), one of the world's leading orchid and [[succulent plant]] collections, have been very popular.<ref name=h11/> With decreasing financial support from governments, revenue-raising public entertainment increased, including music, art exhibitions, special botanical exhibitions, theatre and film, this being supplemented by the advent of "Friends" organisations and the use of volunteer guides.<ref>Looker in {{Harvnb|Aitken|Looker|2002|pp=99–100}}</ref>
