What it is like
The hybrid Rumex patientia x tianschanicus (Hybrid sorrel) is a good Carbon Farming plant. Rumex patientia x tianschanicus. Staple Crop: balanced carb and Industrial Crop: biomass.
Rumex patientia is a PERENNIAL growing to 1.5 m (5ft) by 0.5 m (1ft 8in). See above for USDA hardiness. It is hardy to UK zone 6 and is not frost tender. It is in flower from June to July, and the seeds ripen in August. The species is hermaphrodite (has both male and female organs) and is pollinated by Wind. It is noted for attracting wildlife. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Height (m): 1.5

How it is used
Food
Rating: 3
Leaves - raw or cooked. Eaten like spinach or made into a delicious puree, they are often mixed with a quarter part of sorrel in order to add flavour to them. A fairly mild flavour, they make an excellent vegetable. The leaves are produced very early in the year. Carbon Farming - The hybrid Rumex patientia x tianschanicus is a good staple crop: balanced carb.
Medicine

Experimental Crop: Plant breeders are testing these plants to see if they could be domesticated for cultivation, but they are still in an experimental phase. Examples include milkweed and leafy spurge.
Industrial Crop: Biomass: Three broad categories: bamboos, resprouting woody plants, and giant grasses. uses include: protein, materials (paper, building materials, fibers, biochar etc.), chemicals (biobased chemicals), energy - biofuels
Management: Coppice: Cut to the ground repeatedly - resprouting vigorously. Non-destructive management systems maintaining the soil organic carbon.
Management: Standard: Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
Staple Crop: Balanced carb: (0-15 percent protein, 0-15 percent oil, with at least one over 5 percent). The carbohydrates are from either starch or sugar. Annuals include maize, wheat, rice, and potato. Perennials include chestnuts, carob, perennial fruits, nuts, cereals, pseudocereals, woody pods, and acorns.

How it is grown
A very easily grown plant, it succeeds in most soils, preferring a moist moderately fertile well-drained soil in a sunny position. Formerly cultivated for its edible leaves, these can be available in early February if the winter is mild. An important food plant for the caterpillars of many species of butterfly.The hybrid Rumex patientia x tianschanicus (Hybrid sorrel) is a good Carbon Farming plant. Rumex patientia x tianschanicus cultivation: new crop. Management: standard, coppice. Staple Crop: balanced carb. Industrial Crop: biomass.
Propagating it: Seed - sow spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring.
Best place to grow:
Habit: Perennial
Hardiness: 5-10

Things to keep in mind
Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.
