  Lady's Thumb (Polygonum persicaria) ~ LuminEarth's How to Identify Wild Edible & Medicinal Plants
Becki Baumgartner
 
   
 
About

Uploaded on Sep 29, 2010

Lady's Thumb is an annual plant and a member of the buckwheat family. It has narrow, pointed lance shaped leaves ranging in size from 1 1/2 to 4 inches long. Often there is a darkened triangular spot toward the center resembling a lady's thumbprint. These plants have a cluster of tiny pink flowers growing up from the stalk. Lady's Thumb is a common weed and grows on lawns, meadows, open sunny areas and disturbed soils. There are no poisonous plants that resemble Lady's Thumb, so once you learn it, it is one of the most easiest recognized and safest of the wild edible plants. Lady's Thumb is a member of the subgroup called Smartweeds. Please note that even though Lady's Thumb is sometimes called "Smartweed", it's taste and medicinal properties differ from other members of the smartweed family. Many of the other plants are very hot and peppery, and have stronger medicinal properties. Lady's Thumb good to eat from mid-spring to late fall. The leaves, flowers and shoots can be eaten raw or cooked and are mild tasting, similar to lettuce.

Lady's Thumb goes by a lot of different common names. All of them are often called knotweeds by locals. The dark chevron on the young leaves is a distinguishing characteristic of Lady's thumb. Lady's thumb can be a trail side snack or a pot herb. A first cousin too Lady's Thumb is Alpine smartweed. for Alpine smartweed use the bulblets & roots. I still think it tastes like grass.
