The South London Botanical Institute (SLBI) supports London’s smallest botanic garden, which is densely planted with more than 500 labelled species in themed borders. Traditional medicinal herbs grow beside plants used in current pharmaceutical research. Ferns, carnivorous plants, British natives, scented plants, monocots and drought-tolerant plants feature alongside rare trees and shrubs from the southern hemisphere. There is also a new food plant trail. A new moss trail has been created with each species linking to information online. There is a new pond and wetland area with access for pond dipping, and new planting to provide a home for frogs and newts. Other features include a specially commissioned mosaic to celebrate the centenary and a refurbished lecture room.
