Raspberries are native to Europe and northern Asia and commonly cultivated in other temperate regions. It is a perennial plant with bristly, prickly branches about 1-2 m tall, a yellow-brown bark that peels in layers. It has alternate palmate leaves with 3-5 leaflets that are ovate, measuring between 4-10 centimetres long. They are irregularly sharp toothed and pointed leaves. Raspberry flowers grow in clusters from upper leaf axils, with white petals and hairless stamens that bloom in the summer. Raspberries themselves are interestingly not a berry, instead an aggregate fruit of numerous drupelets around a central core. They are sweet and slightly tart, a rich red color and woolly hairs on the exterior.
