We can think of at least 180 great forest garden & perennial crops for cold climate Sweden. Want to hear about them? Over the course of the next year we will profile 5 a week on the blog. Perennial plants and crops offer a low energy, oil & resource input based foundation for future-proof agricultures. By default if an agriculture is to be called regenerative the bottom line is that it must be soil building, not soil depleting. Relentless deep tillage & poor soil husbandry (wifery?!) contributes to the majority of the 24 billion tons of topsoil lost every year on planet water. We are going to be focused on holistic polyculture grazing and perennial production at ridgedale over most of the site as this represents the most effective way to restore our degraded landscape, produce high value produce and ensure the future resource base we are managing holistically for in our decision making.
Common Name Jerusalem Artichoke
Origin North America
The Jerusalem artichoke (Helianthus tuberosus), also called sunroot, sunchoke, earth apple or topinambour, is a species of sunflower native to eastern North America, and found from eastern Canada and Maine west to North Dakota, and south to northern Florida and Texas.
It is a herbaceous perennial plant growing to 1.5–3 m (4 ft 11 in–9 ft 10 in) tall with opposite leaves on the upper part of the stem but alternate below. The leaves have a rough, hairy texture and the larger leaves on the lower stem are broad ovoid-acute and can be up to 30 cm (12 in) long, and the higher leaves smaller and narrower. The flowers are yellow and produced in capitate flowerheads, which are 5–10 cm (2.0–3.9 in) in diameter, with 10–20 ray florets.
The tubers are elongated and uneven, typically 7.5–10 cm (3.0–3.9 in) long and 3–5 cm (1.2–2.0 in) thick, and vaguely resembling ginger root in appearance, with a crisp texture when raw. They vary in colour from pale brown to white, red, or purple. The artichoke contains about 10% protein, no oil, and a surprising lack of starch. However, it is rich in the carbohydrate inulin (76%), which is a polymer of the monosaccharide fructose. Tubers stored for any length of time will convert their inulin into its component fructose. Jerusalem artichokes have an underlying sweet taste because of the fructose, which is about one and a half times sweeter than sucrose.
Reported to be aperient, aphrodisiac, cholagogue, diuretic, spermatogenetic, stomachic, and tonic, Jerusalem artichoke is a folk remedy for diabetes and rheumatism.
The plants are a good source of biomass. The tubers are used in industry to make alcohol. The alcohol fermented from the tubers is said to be of better quality than that from sugar beets.
