A Quince is a small deciduous tree, growing 5-8 m high and 4-6 m wide, that bears a pome fruit, similar in appearance to a pear, and bright golden-yellow when mature. The fruit is 7 to 12 cm long and 6 to 9 cm across. Throughout history the cooked fruit has been used as food, but the tree is also grown for its attractive pale pink blossoms and other ornamental qualities. The immature fruit is green with dense grey-white pubescence, most of which rubs off before maturity in late autumn when the fruit changes colour to yellow with hard, strongly perfumed flesh. The alternate leaves are simple, 6–11 cm long, with an entire margin and densely pubescent with fine white hairs. The flowers, produced in spring after the leaves, are white or pink with five petals. In Turkey, the expression ayvayı yemek (literally "to eat the quince") is used as a derogatory term indicating any unpleasant situation or a malevolent incident to avoid. This usage is likened to the rather bitter aftertaste of a quince fruit inside the mouth.
