It is native to Asia and Europe, and widely naturalized in Canada, the United States, Australia, and New Zealand. |
| Allergen Potential [1] | High |  | | Edible [2] | May be edible. See the Plants For A Future link below for details. | | Flower Type [2] | Monoecious | | Hazards [2] | No member of this genus contains any toxins, all have more or less edible leaves. However, if grown with artificial fertilizers, they may concentrate harmful amounts of nitrates in their leaves.
The seed contains saponins; Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. They can be removed by carefully leaching the seed or flour in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish; | | Lifespan [2] | Annual | | Pollinators [2] | Wind | | Structure [4] | Herb | | Usage [2] | A blue dye is obtained from the seed;
The plant is a potential source of biomass. Yields of 14 tonnes per hectare have been achieved in the vicinity of Landskrona and Lund, Sweden. Higher yields might be expected farther south. If the leaf-protein were extracted, this should leave more than 13 tonnes biomass as by-product, for potential conversion to liquid or gaseous fuels; | | | Height [2] | 5.904 feet (1.8 m) | | Width [2] | 12 inches (0.3 m) | | | Light Preference [3] | Mostly Sunny | | Soil Acidity [3] | Neutral | | Soil Fertility [3] | Rich | | Soil Moisture [3] | Moist |
