A Rowan tree in autumn with yellow-orange coloured leaves and clusters of red berries.
Description from Wikipedia (http://en.wikipedia.org/wiki/Sorbus_aucuparia):
Sorbus aucuparia (Rowan, European Rowan, Mountain ash, or European mountain ash), is a species of the genus Sorbus, native to most of Europe except for the far south, and northern Asia.
It is a small to medium-sized deciduous tree typically growing to 8–10 m tall, more rarely 20 m, and exceptionally to 28 m.
The fruit, called rowan berries in culinary usage, are usually quite bitter, but are used to make jam or jelly, with a distinctive bitter flavour. Due to wide range of European Rowan, fruits are used in many national kitchens to add their distinctive sour/bitter flavour to dishes or drinks. Rowan jelly is a traditional accompaniment to game and venison.
The fruit is an important food resource for many birds, notably Redwings, Fieldfares, Blackbirds, Mistle Thrushes and Waxwings, which in turn disperse the seeds in their droppings. The seeds are eaten by Pine Grosbeaks and other large finches.
