Common Name Swamp Dock
Family Polygonaceae
USDA hardiness Coming soon
Known Hazards 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[238].
Habitats Moist places such as the banks of creeks, often in clay soils, in the montane and sub-alpine zones[154]. Often found as a weed of damp lawns and pastures in Australia[193].
Range Australia - New South Wales, Queensland, South Australia, Tasmania, Victoria. Casual in Britain[17].
