Azaleas in Hyde Park London – The Isabella Plantation is a 40 acre woodland garden set within a Victorian woodland planted in the 1830’s. First opened to the public in 1953, it is best known for its evergreen azaleas, which line the ponds and streams and at their peak of flower in late April and early May. Located in the gardens are the National Collection of Wilson 50 Kurume Azaelas (introduced to the west from Japan in the 1920’s by the plant collector Ernest Wilson), large collections of Rhododendrons and Camellias, plus many other rare and unusual trees and shrubs which provide interest all year round.
