Plantae > Tracheophyta > Magnoliopsida > Caryophyllales > Polygonaceae > Rumex > Rumex venosusRumex venosus (veiny dock)Synonyms: Lapathum venosum (homotypic) Rumex venosus is a species of flowering plant in the knotweed family known by the common names veiny dock, winged dock, and wild-begonia (it is not related to genus Begonia). While not of any particular agricultural use, its cousins Rhubarb and Buckweat are. It is native to central and western North America, from southern parts of the Canadian prairies, through to Mexico. It can be found in many types of habitat, including sagebrush, dunes, and other sandy areas. It is commonly found in heavily grazed pastures as livestock tend to avoid it, allowing veiny dock to spread uninhibited. |
Allergen Potential [1] | Medium-Low | | Edible [2] | May be edible. See the Plants For A Future link below for details. | Flower Type [2] | Hermaphrodite | Hazards [2] | 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; | Lifespan [2] | Perennial | Pollinators [2] | Wind | Structure [3] | Herb | Usage [2] | A yellow dye is obtained from the root; The roots are peeled, broken into sections about 25mm long, then spread out thinly in a sunny position until very dry. They are then soaked in water for a few days before being boiled in the same water for a long time. Alum is then added to fix the colour; A red dye is obtained if ashes are added and it turns black if the bark of Cornus stolonifera is also added; | | Height [2] | 20 inches (0.5 m) | View Plants For A Future Record : Rumex venosus |
