Fruit Edible

Cydonia oblonga 'Iranian' (F)

A small, rounded, deciduous tree, with solitary, pale pink and white flowers in spring which require a period of fairly low temperatures (under 7 degrees centigrade) in order to bloom. Large, pear-shaped, fragrant, deep yellow fruit follow in autumn which, unusually, are suitable for eating raw straight from the tree. Both young foliage and fruit have a downy, silvery-grey coating

How to grow

Cultivation

Grow in a warm, sheltered spot as flowers are susceptible to frost and warm conditions are needed for the fruit to ripen well. Tolerant of a wide range of soils, but will do best where soil is deep and moisture retentive, so long as it is not prone to waterlogging. See quince cultivation

Propagation

Propagate by grafting or by semi-ripe or hardwood cuttings
