The gardens were founded by a local group of working men, known as the Southport and Churchtown Botanic Gardens Company. The company acquired land from the Hesketh Estate to establish the gardens. The company raised £18,000 to build the museum, a conservatory and tea rooms and to landscape the gardens. The Botanic Gardens' lake was formed from part of a stream that flowed from Blowick through Meols Hall out to the Ribble Estuary. It is said that monks who lived nearby fished for eels in the stream. Until recently the flow of this stream had been intentionally blocked for 20–30 years at the point where it passed into the Gardens under Botanic Road, but this conduit was reopened in 2012. The gush of water out of the lake on re-opening sluiced away silt and mud in the stream bed, briefly exposing the cobbled ford which predated the road bridge. The gardens were officially opened in 1875 by Rev. Charles Hesketh, from whom the land occupied by the gardens has been acquired. The ceremony included the laying of a foundation stone for the museum, which eventually opened in 1876. The gardens closed in 1932, as plans had been drawn up for housing development, but were saved from being sold by the Southport Corporation. They reopened on 28 August 1937 as "The Botanic Gardens and King George Playing Fields". Today, the park's name has been reverted to Botanic Gardens.
Conservatory
The gardens boasted a large glass conservatory with a fernery, which proved very popular with visitors, as it featured many tropical plants from around the world. Although the magnificent conservatory was eventually demolished, the fernery still remains. The site of the conservatory can still be seen in front of the fernery today, as the outline of the remains is laid out as a floral garden.
Botanic Gardens Museum
The Botanic Gardens Museum was opened in 1876. It was designed by the local architects Mellor & Sutton of London Street and built by George Duxfield of Duxfield Brothers, Southport. The famous showman Phineas T. Barnum was an advisor in the construction of the museum, and his top hat was on display in the museum. The running of the museum was funded by donations from the public and Sefton Council. It was the only local-history museum in Sefton.
New collection
When the gardens closed in 1932, all the collections were sold off. The museum was later reopened by John Scoles, who started from scratch a new collection. The museum contained a number of fine collections—many of which have been donated by local residents—and its exhibits dealing with natural and local history include the Cecily Bate Collection of Dolls, a Victorian room and many local artefacts relating to Southport's heritage. One special item, and probably the oldest item in the museum is the ancient canoe which was found in Martin Mere.
Friends of the Botanic Gardens Museum
During the 1980s the Friends of the Botanic Gardens Museum organization was formed. They stopped the proposed closure of the museum at the time. The Friends had their own shop within the museum building.
Closure
The Botanic Gardens Museum was closed as part of a cost-cutting exercise by Sefton Council on 24 April 2011. The exhibits have to some extent been dispersed. The Pennington taxidermy collection was permanently transferred to the British Historical Taxidermy Society Trust, based in Essex, in controversial circumstances. This was despite significant interest from National Museums Liverpool, who wanted to take on part of the collection and keep it in Merseyside. The collection has since been returned to Sefton Council and resides in the Atkinson Museum in Southport. The Martin Mere canoe is now displayed in the Atkinson Library, next to Southport Town Hall on Lord St. At the same time, horticultural activities at the gardens were significantly reduced. The flower beds are now maintained and entered into Britain In Bloom each year by the Botanic Gardens Community Association of volunteers who spend Mondays and Fridays every week of the year tending to as much of the park as they can. They have big hopes and dreams to return the gardens to their former splendour.
2012 Campaign
Sefton Council highlighted for further closures within the park which would see the loss of the Botanic Gardens Fernery, Aviary, Garden Nursery and Toilets along with the Conservatory at Hesketh Park. A group of local residents formed to save the remaining facilities at both parks, in particular at Botanic Gardens, which has already lost the museum, boats on the lake, boat house, road train that provided a ride around the park and job losses of park gardeners.
