Rumex are hardy perennial herbs that range from 45 to 60 cm in height.
They have green arrow shaped leaves that can be used in soups, and come into bloom in the middle of summer.
Common names for Rumex genus members is Sheep's Sorrel, Sour weed, and Field sorrel
If growing for culinary use it is recommended that you use Rumex scutatus (French Sorrel).
Rumex venosus by Matt Lavin.
Due to their fecund nature it is best to grow Sorrel in containers to separate them from other members of the herb garden. The Sorrel seeds should be sown at a depth of 6 mm in the middle of spring.
The container that Rumex grows in should have a rich acidic soil (pH 5.5 to 6) that is moist, and the container should be placed into a sunny area of the garden. The Sorrel plants should be spaced about 30 to 40 cm apart if using a very large container or singularly in smaller containers.
If starting off indoors then sow sorrel seeds about a month before the last frost. They should take about 9 or 10 days to germinate at 18 to 20 degrees centigrade. Transplant them outdoors just after the last frost.
Easy to look after but difficult to control due to their prolific seed production. In the spring time supply Rumex plants with a feed and a mulch. It is best to water regularly as this prevents the sorrel leaves from having a bitter taste. After three years replace sorrel plants as they tend to lose both vigor and flavor.
Classified as a Noxious weed in many areas. As it grows from rhizomes it spreads easily and is diificult to control.
