to the Truckee Meadows.
Horsetail, also known as scouring rush, is an evergreen, reed-like plant that grows to about 3 feet tall. Their jointed stems are cylindrical and hollow.
Horsetails have been around for 400 million years!
Around 350 million years ago, during the Devonian period, horsetail ancestors grew in thick forests tall as trees.
Horsetails reproduce via spores.
The plants have abrasive silica inside the hollow stems. This grittiness was used to scour and clean goods as well as pots and pans.
