The wild apple is a small tree occurring naturally in Europe. It is a somewhat irregularly growing tree with a fairly loose, rounded crown. The bark is grey and flakes off in small plates. Sometimes the young red-brown twigs carry thorns. The ovoid to oval leaves are glossy green. The leaf edge is serrated. The flowers appear in May at the same time as the leaves. They are pale pink to white and measure approx. 3 - 4 cm. The round to ovoid fruits appear after the flowers. They are greenish-yellow sometimes with a red blush on the sunny side. Wild or escaped apples are often sweet. The tree prefers nutritious soil. M. sylvestris is one of the ancestors of the enormous range of fruits currently cultivated.
