Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils and can grow in very acid soils.

Edible Uses

Edible Parts: Seed
Edible Uses:

Seed - raw or cooked[1, 46, 61]. A good potato substitute[63, 105, 142, 171]. A source of starch[177]. Very poor flavour[142]. Coarse and of little value. Very variable in size and quality, any astringency can be removed by boiling the seed in salty water[183].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


None known

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Tannin  Wood

The bark, leaves, wood and seed husks all contain tannin. Wood - hard, strong, light, very durable. Used for furniture, construction, fence posts etc[46, 61].

Cultivation details

Industrial Crop: Tannin  Management: Standard  Regional Crop  Staple Crop: Balanced carb

Prefers 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[200]. Averse to calcareous soils but succeeds on harder limestones[11, 200]. The majority of species in this genus only really thrive in areas with hot summers, though this species is better adapted to British conditions than most[200]. Cultivated for its edible seed in Japan, there are many named varieties[58, 63, 183]. It is often also cultivated for its seed in America because it is fairly resistant to chestnut blight[171, 200]. Individual trees are very variable with regard to size of the seed, resistance to blight and astringency of the seed[183]. Some cultivars have the largest seeds of any member of this genus. Trees fruit freely when only 3 - 3.5 metres tall[11]. This species is occasionally planted as a timber tree in S. Europe[50]. An excellent soil-enriching understorey in pine forests[200]. Flowers are produced on wood of the current year's growth[229]. Plants are fairly self-sterile[200]. They hybridize freely with other members of this genus[200]. Plants in this genus are notably resistant to honey fungus[200].

Propagation

Seed - where possible sow the seed as soon as it is ripe in a cold frame or in a seed bed outdoors[78]. 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].
