The slippery elm occurs in north-eastern United States and southern Quebec. It can grow to 83 feet high (25 metres) and live 125 years.
The leaves are covered on both sides in a fine whitish hair. They also give off a fragrant odour when dry.
The fruit is a round key with reddish-coloured hairs covering the seedcase. The flowers occur in clusters on the stalks.
Its inner bark is quite particular. Apart from its fragrant odour, it contains an aromatic substance called coumarin, which is useful for curing inflammatory infections.
