The sycamore is a tall, domed tree of the maple family. Its five-lobed leaves have toothed margins and characteristic red stalks. Its small, green flowers hang in spikes, turning to distinctive winged fruits known as 'samaras'.
It can be found in parklands, hedgerows and woodlands and was introduced into the UK from Europe sometime in the 15th or 16th century and has become naturalised since, as well as being widely planted.
Due to its winged seeds (known as 'helicopters'), produced in profusion in mature trees, and its adaptability, it can colonise all kinds of habitats, including waste ground.
