These plants are seldom more than 30 centimeters tall. They
have alternate leaves, often with arrow-like bases, very small
flowers, and frequently reddish stems.
Habitat and Distribution
Look for these plants in old fields and other disturbed areas
in North America and Europe.
The plants are edible raw or cooked.
These plants contain oxalic acid that can be damaging if too
many plants are eaten raw. Cooking seems to destroy the chemical.
The leaves are often reddish in some areas. Once you get to
know the green-reddish look that the patches of these plants
have, you can spot them from a long distance away.
Sheep sorrel, like wood sorrel and the common shamrock, is
delicious and thirst-quenching in small quantities. The oxalic
acid means you shouldn't eat much.
