Cultivation DetailsPrefers a good well-drained slightly acid loam but succeeds in dry soils[1, 11, 200]. Once established, it is very drought tolerant[1, 11, 200]. Very tolerant of highly acid, infertile dry sands. Averse to calcareous soils but succeeds on harder limestones[11, 200]. Although it is very winter-hardy, this species only really thrives in areas with hot summers. It is very slow growing and small in Britain[11, 200]. A shrub at Kew was 3 metres tall in 1990[K]. Resists endothia blight. Plants in this genus are notably resistant to honey fungus. An excellent soil-enriching understorey in pine forests. Flowers are produced on wood of the current year's growth. Plants are fairly self-sterile. They hybridize freely with other members of this genus.
Edible Uses** See disclaimer
Edible Rating: 3/5
Seed - raw or cooked[105, 177]. Small[61, 63]. Said to be of excellent eating quality. Eaten raw, there is a distinct astringency, especially if the fleshy inner skin beneath the outer shell of the seed is not removed[K]. When cooked, however, and especially when baked, the seed becomes much sweeter and has a floury texture[K]. It then makes an excellent food and can be used as a staple food in much the same way as potatoes or cereals[K].
- Seed - includes nuts, cereals, peas and beans.

PropagationSeed - where possible sow the seed as soon as it is ripe in a cold frame or in a seed bed outdoors. The seed must be protected from mice and squirrels. The seed has a short viability and must not be allowed to become dry. It can be stored in a cool place, such as the salad compartment of a fridge, for a few months if it is kept moist, but check regularly for signs of germination. The seed should germinate in late winter or early spring. If sown in an outdoor seedbed, the plants can be left in situ for 1 - 2 years before planting them out in their permanent positions. If grown in pots, the plants can be put out into their permanent positions in the summer or autumn, making sure to give them some protection from the cold in their first winter[K].
