Succeeds in most soils that are well-drained, though it dislikes shallow chalk soils. It prefers a soil that is only moderately fertile, succeeding in very poor soils and in dry soils. Prefers a light sandy loam and a sunny position. Established plants are very drought resistant. A very hardy plant, tolerating temperatures down to at least -40°c. This species is somewhat similar to E. multiflora, but it flowers a few weeks later. Sometimes cultivated for its edible fruit, there are some named varieties. 'Cardinal' and 'Red Wing' are very good fruiting forms (developed for ornament and not for fruit quality). 'Jazbo' has been bred for its edible fruits which are said to be ripe when 'they drop into your hand'. This makes them valuable in breeding programmes to develop easily harvested fruits. Flowers are rich in nectar and very aromatic, they are much visited by bees. Polymorphic. This species is notably resistant to honey fungus. Plants can fruit in 6 years from seed. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. An excellent companion plant, when grown in orchards it can increase yields from the fruit trees by up to 10%.
Fruit - raw or cooked. Juicy and pleasantly acid, they are tasty raw and can also be made into jams, preserves etc. The fruit must be fully ripe before it can be enjoyed raw, if even slightly under-ripe it will be quite astringent. The fruit contains about 8.3% sugars, 4.5% protein, 1% ash. The vitamin C content is about 12mg per 100g. Mature bushes in the wild yield about 650g of fruit over 2 - 3 pickings. The harvested fruit stores for about 15 days at room temperature. The fruit is about 8mm in diameter and contains a single large seed. Seed - raw or cooked. It can be eaten with the fruit though the seed case is rather fibrous.
Seed - best sown as soon as it is ripe in a cold frame. It should germinate in late winter or early spring, though it may take 18 months. Stored seed can be very slow to germinate, often taking more than 18 months. A warm stratification for 4 weeks followed by 12 weeks cold stratification can help. The seed usually (eventually) germinates quite well. Prick out the seedlings into individual pot as soon as they are large enough to handle and plant out when they are at least 15cm tall. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame. Good percentage. Cuttings of mature wood of the current year's growth, 10 - 12cm with a heel, November in a frame. Leave for 12 months. Fair to good percentage. Layering in September/October. Takes 12 months.
Thickets and thin woods in the lowland and hills.
