Erdmandel

A top-tier edible sedge that combines resilience with nutritional density. Growing Conditions: Thrives in moist soils but tolerates moderate drought once established. Habitat & Range: Native to parts of Eurasia and Africa; now widespread across temperate and subtropical regions. Size & Landscape Performance: Dense stands may outcompete neighboring plants. Cultivation (Horticulture): Easy to grow but difficult to contain. Pests & Problems: Few natural predators; persistence is the main challenge. Identification & Habit: Triangular stems, narrow leaves, and golden seed heads distinguish it. Pollinators: Primarily wind-pollinated; seeds feed birds. Prefers a moist sandy loam. Plants are hardy to about -15°c. The chufa, or tiger nut, is often cultivated for its edible tuber in warm temperate and tropical zones, there is a cultivated variety, var. sativus, that produces larger tubers. We have had lots of problems with growing this cultivated form. Once the tubers come into growth then they normally grow vigorously, but the difficulty is getting them to come into growth. We harvest the tubers in the autumn and store them in moist sand, replanting them in the spring. However, they rarely come into new growth until mid to late summer which gives them too short a growing season to produce much of a crop[K]. We need to find a satisfactory way of storing the tubers and exciting them back into growth[K]. In warmer climates this plant is a serious weed of cultivation. It is much hardier than was once imagined and is becoming a weed in N. America where it is found as far north as Alaska. The tubers are often formed a metre or more away from the plant, especially if it is growing in a heavy clay soil. The tubers are extremely attractive to mice and require protection from them in the winter[K]. Plant Name: Chufa. Family: Cyperaceae. Genus: Cyperus. Common Names: Yellow nutsedge, chufa, earth almond. USDA Hardiness Zones: Approximately 5–10. Height/Spread: 30–90 cm tall; spreads via rhizomes forming loose colonies. Introduced into: Austria, Belgium, Cambodia, China North-Central, Germany, Hawaii, Hungary, Japan, Jawa, Mauritius, New Guinea, New South Wales, New Zealand North, Poland, Réunion, St.Helena, Taiwan, Tristan da Cunha, Ukraine, Vietnam.

Edible Parts: Leaves Oil Oil Root Edible Uses: Coffee Oil Oil Both tubers and seeds are edible, with tubers representing the primary food resource. Edible Uses & Rating: Rated high among wild sedges. Tubers are calorie-dense, nutritious, and versatile [2-3]. Taste, Processing & Kitchen Notes: Tubers have a pleasant sweetness with nutty undertones. Raw tubers can be firm; soaking softens them. Roasting enhances flavor, while boiling produces a potato-like texture. Ground tubers yield flour suitable for baking or beverages [2-3]. Seasonality (Phenology): Tubers develop through summer and are best harvested in autumn, though they may persist underground into winter [2-3]. Safety & Cautions (Food Use): Wetland pathogens remain a concern; wash thoroughly and cook when possible. Harvest & Processing Workflow: Loosen soil to uncover clusters of tubers. Wash to remove grit, then dry, roast, or grind as desired [2-3]. Cultivar/Selection Notes: Selected forms exist for agricultural production, particularly in Spain. Look-Alikes & Confusion Risks: Distinguished from purple nutsedge by its lighter foliage and sweeter tubers. Traditional/Indigenous Use Summary: Widely used by Indigenous peoples and later cultivated globally, reflecting exceptional food value [2-3]. Tuber - raw, cooked or dried and ground into a powder.They are also used in confectionery. A delicious nut-like flavour but rather chewy and with a tough skin[K]. They taste best when dried. They can be cooked in barley water to give them a sweet flavour and then be used as a dessert nut. A refreshing beverage is made by mixing the ground tubers with water, cinnamon, sugar, vanilla and ice. The ground up tuber can also be made into a plant milk with water, wheat and sugar. An edible oil is obtained from the tuber. It is considered to be a superior oil that compares favourably with olive oil. The roasted tubers are a coffee substitute. The base of the plant can be used in salads. (This probably means the base of the leaf stems[K])

Oil Oil Weaving The tubers contain up to 30% of a non-drying oil, it is used in cooking and in making soap. It does not solidify at 0°c and stores well without going rancid. The leaves can be used for weaving hats and matting etc. The boiled nuts are used in the UK as a bait for carp. Tubers are eaten by mammals; foliage shelters insects.
