Ealing Common preserves a large area of open space with fine avenues of horse chestnut trees, most of which were planted in the late Victorian period, following the purchase of the common land by the Ealing Local Board. The northern part of the common has a large English oak tree at its centre, and London plane trees are also found with the horse chestnuts around the perimeter of the common. Charles Jones was the borough surveyor responsible for the layout. In the south-west corner of Ealing Common, there is a small enclosed park, called Warwick Dene, with rose beds at its centre. There is a local Conservation Area which includes streets around the common. Ealing Common is also the name of the area in the London Borough of Ealing surrounding Ealing Common station, which is named after the common; however, it is officially part of the Ealing district.
