The second annual Camellia Festival kicks off in  gardens surrounding the neo-Palladian property, Chiswick House,  in west London this weekend. The month long festival, run by the Chiswick House & Gardens Trust, was kicked off in 2011 with the aim of showcasing Chiswick’s world renowned Camellia Collection, believed to be the largest in the Western world. Following the success of last year’s festival following a £12.1 million garden restoration project, the flowers will once again be on display in the Conservatory (designed by Samuel Ware in 1813). Complementing the display of camellias will be a showcase of early spring flowers planted in the newly restored Italian Garden (originally created for the 6th Duke of Devonshire in 1814, it was, at the time, at the forefront of horticultural fashion). The Camellia Collection, meanwhile, includes rare and historically significant plants featuring pink, red, white and striped blooms, many of which are descended from the original planting in 1828. Among them is the Middlemist’s Red which was originally brought to Britain from China in 1804 by John Middlemist, a nurseryman from Shepherds Bush. It is one of only two in the world known to exist (the other is in Waitangi in New Zealand). The festival runs from the 18th February to the 18th March.  Admission charge applies.
