[2] The Old English Cottage Garden was originally named for Lt-Col JJ Sexby, first Parks Superintendent for the London County Council.
[3] A "Tree of Heaven" (Ailanthus glandulosa) is also planted there, which had a symbolic meaning in relation to Salter's Quaker beliefs.
The park is also home to Southwark parkrun, one of the many free, weekly 5k runs held in both the UK and internationally.
[7] As with many spaces within London, the Plane tree (Platanus × hispanica) is dominant within Southwark Park, particularly the northernmost section around the bandstand, which runs next to Jamaica Road.
Opposite the entrance to the art gallery is a walnut tree (Juglans regia) and a series of three or four silver maples (Acer saccharinum).
Next to the duck pond and the garden area are three swamp cypresses (Taxodium distichum), although without the distinctive wooden 'knees' which sometimes surround trees of this variety.
