In excess, however, it can cause respiratory failure and even death.

Edible Uses

Edible Parts: Fruit.
Edible Uses:

Fruit - raw, cooked in pies, preserves etc, or dried for later use[62, 101, 183]. A bitter flavour[212]. The fruit becomes sweeter and so tastes best after a frost, it can also be bletted if it is going to be eaten raw[K]. This involves storing the fruit in a cool dry place until it is almost but not quite going rotten. At this stage the fruit of many species has a delicious taste, somewhat like a luscious tropical fruit. The fruit is up to 5mm across[200].

Other Uses

Wood.

The wood is soft and weighs 37lb per cubic foot[235].

Cultivation details

Succeeds in most reasonably good soils in an open sunny position[11]. Dislikes dry soils[188]. Tolerates light shade[188], though it fruits better in a sunny position[K]. Plants are susceptible to fireblight[188].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[78, 80]. If you have sufficient seed it can be sown in an outdoor seedbed[78, 80]. Stored seed germinates better if given 2 weeks warm then 14 - 16 weeks cold stratification[98], so sow it as early in the year as possible. Prick out the seedlings into individual pots when they are large enough to handle. Seedlings are very slow to put on top-growth for their first year or two[11], but they are busy building up a good root system. It is best to keep them in pots in a cold frame for their first winter and then plant them out into their permanent positions in late spring.
