Botanic Garden Meise

The Meise Botanic Garden, until 2014 called the National Botanic Garden of Belgium, is a botanical garden located in the grounds of Bouchout Castle in Meise, Flemish Brabant, just north of Brussels. It is one of the world's largest botanical gardens, with an extensive collection of living plants and a herbarium of about 4 million specimens. The current garden was established in 1958 after moving from central Brussels; the former site is now the Botanical Garden of Brussels.

The Meise Botanic Garden contains about 18,000 plant species—about 6% of all the world's known plant species. Half are in greenhouses, the other half, including cultivated and indigenous plants, are outdoors. The Index Herbariorum code assigned to this botanic garden is BR, which is used when citing housed specimens.
