     I remember picking wildflowers as a little girl in North Florida. My favorite ones were always the purple flowers. Flowers like Spiderwort. Tradescantia virginiana is a three petaled, clump forming species in the Tradescantia family. This family includes a large number of plants that are used as ornamentals. The virginiana, however, is commonly considered a weed, and somewhat invasive, here in Central Florida. However, this tall, grass-like plant has a few fans that can't help but keep it in their gardens as a point of interest.

     This plant is high in mucilage, a slimy substance that provides a host of medicinal benefits. However it may have been the origin of a few different common names given to this plant. If you break a tip off of a leaf, or break the stem, then take some of the sap on your finger, when touched by another finger and slowly pulled away it will form a long slender string. This string resembles a spider’s silk. This is one origin of the common name Spiderwort or even the common name of Cow Slobber. However, the most commonly given origin for the name Spiderwort comes from it's traditional use for spider bites.

     Tradescantia virginiana is a traditional edible plant that can be prepared in a number of ways. However it's just one species in the Tradescantia family, and not every species is edible. But Spiderwort can be an excellent addition to your family's wild food list. The stems and young shoots can be steamed like asparagus, the leaves and flowers make a great addition to a salad, or dessert. The flowers were also used as a traditional decoration for cakes and other baked goods.
     There is one really amazing trait that these flowers posses. They are natural radiation detectors. The stamens of the flowers have fine hairs on them, that are typically a blueish purple. However, when exposed to levels of radiation that are dangerous, those fine hairs turn pink. If the dangerous pollutants get to be really dangerous, the whole flower will turn pink. So just like Marvel's Spiderman, who was bitten by a radioactive spider, the Amazing Spiderwort can be your hero and save you from danger.
