Allergen Potential [1]  Medium-High
Light Preference [3]  Mostly Sunny
Soil Acidity [3]  Neutral
Soil Fertility [3]  Intermediate
Soil Moisture [3]  Moist
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 [4]  Herb
Usage [2]  Yellow, dark green to brown and dark grey dyes can be obtained from the roots. They do not need a mordant; An alternative ingredient of 'QR' herbal compost activator; (is it the flowers?) This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost;
