Oriental Lady’s Thumb (Persicaria longiseta) is an edible, non-native plant from Asia. It can be identified by its alternate leaves and small pink flowers.

All above ground parts of oriental lady’s thumb are edible raw or cooked. It has a peppery taste.

Oriental lady’s thumb might be confused with lady’s thumb (Persicaria maculosa) which has a thumb-print looking splotch on its leaves and lacks the long hairs that grow from the base of the flower. Lady’s thumb and other close look-a-likes are also edible.

Oriental lady’s thumb and lady’s thumb have been used medicinally to treat stomach pains and poison ivy.
