The Botanic Garden, like the Herbarium, was refounded by Professor John Stevens Henslow. Henslow’s view was that the Botanic Garden should provide for the study of plants themselves, rather than as a physic garden or an economic garden. Ours is the first Botanic Garden founded on this principle. The trees were planted in groups to demonstrate variation within species, species and their hybrids, and mutations (or ‘monstrosities’ as they were called). These groups demonstrate Henslow’s fascination with variation and the definition of species, well before the ‘Origin of Species’ was written.
