The Oriental Plane Platanus orientalis, native to Turkey, South East Europe and India, was introduced to Britain in 1550. It was common in Persian Gardens where it was known as the Chenar. It is not common in Britain but can be found in parks and gardens in Southern England. It can be confused with the London Plane but the 5-lobed leaves are cut much deeper and the spherical fruits are smaller.
Female flowers with red stigmas are ready to receive pollen in May. The flowers are clustered into spheres. Each female flower has 6 to 9 crimson stigmas. The tree is monoecious with separate spherical clusters of male and female flowers on the same tree.
When pollinated each flower develops into a fruit called an achene.The fruiting spheres are smaller than those of the London Plane. Photo taken in December.
The seeds are packed round the outside of the sphere and are ready to be dispersed in spring. Photo taken in April. The fruit of the Oriental Plane is a dense ball of individual fruits called achenes. Each achene consists of one seed with a style and hair attached. The styles stick out in this close-up photo. The hairs, which aid wind dispersal, are inside the ball.
