DESCRIPTION: A small, bushy, irregular, deciduous thornless shrub or small tree reaching about 4-6 m in height and 3-4.5 m in width, with crowded gnarled branches and a low crooked habit. Young branchlets are covered with a pale greyish wool. Fruits are light golden-yellow, green or orange, usually pear shaped (but sometimes round and apple-shaped - sometimes classified as cv ŒMaliformis‚) and very fragrant. The fruit pulp is firm, aromatic and always contains gritty cells. Individual fruits can weight up to ∏ Kg or more, and ripen late in the autumn. Fruits contain seeds which are poisonous. USES: A gum is obtained from the seed coats and used as a laxative, and as an emulsifying and stabilizing agent in medical preparation and in cosmetics, and demulcent lotions. The fruit is used for preserves and jellies. KILLING T Quinces are generally hardy to -15 to -25°C, but have a low chilling requirement (much less than most apples) - 100 to 450 hours below 7°C in order to flower. GROWING PERIOD Slow-growing perennial. First harvest may be taken after 2 years and the tree has an economical life of 25 years. COMMON NAMES Quince, Coing, Membrillo, Quitte.
