Quince (Cydonia Oblonga)
It is hardy to zone 4. It flowers in May, and the fruits ripen in November. The flowers are pollinated by Insects.
When grown in warm climates the fruit can become soft and juicy and is suitable for eating raw. In cooler climates such as Britain, however, it remains hard and astringent and needs to be cooked before being eaten. It is used in jellies, preserves etc. The cooked fruit adds a delicious flavour to cooked apples. The fruit is rich in pectin.
Succeeds in most soils but prefers a light moist fertile soil and a sunny position. Dislikes very dry or waterlogged soils. The quince has been cultivated for over two thousand years for its edible fruit and its seed, though it is not a widely grown crop.
