Japanese quince

The leaves are alternately arranged, simple, and have a serrated margin. The flowers are 3–4.5 cm diameter, with five petals, and are usually bright orange-red, but can be white or pink; flowering is in late winter or early spring. The fruit is a pome with five carpels; it ripens in late autumn.
Chaenomeles is used as a food plant by the larvae of some Lepidoptera species including Brown-tail and the leaf-miner Bucculatrix pomifoliella.
