Attributes

Allergen Potential [1]  Medium-High
Edible [2]  May be edible. See the Plants For A Future link below for details.
Flower Type [2]  Dioecious
Hazards [2]  Although no specific mention has been made for this species, there have been reports that some members of this genus can cause photosensitivity in susceptible people. Many species also contain oxalic acid (the distinctive lemony flavour of sorrel) - whilst not toxic this substance can bind up other minerals making them unavailable to the body and leading to mineral deficiency. Having said that, a number of common foods such as sorrel and rhubarb contain oxalic acid and the leaves of most members of this genus are nutritious and beneficial to eat in moderate quantities. Cooking the leaves will reduce their content of oxalic acid. 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
Structure [4]  Shrub
Usage [2]  A potential source of biomass. Plants are very vigorous and could be grown as a ground cover;
Height [2]  11.808 feet (3.6 m)
Width [2]  9.84 feet (3 m)
Light Preference [3]  Mostly Sunny
Soil Acidity [3]  Neutral
Soil Fertility [3]  Rich
Soil Moisture [3]  Damp
