When I was in college, I took several botany classes. One of the plants I loved to draw in my lab journal was Horsetail. It looked so primitive.
Horsetail is considered a "living fossil." The genus is over 300 million years old and the plants were prevalent in Paleozoic forests. Some varieties grew to tree heights up to 30 metres tall.
Field Horsetail (Equisetum arvense) grows in moist spots along streams, sandy places, disturbed or open areas, and shady forests. It's considered a weed when it is located in agricultural and landscaped areas, and it can be poisonous if grazing animals eat it in large quantities. Their deep, interconnected root structure makes them difficult to eradicate. But in nature, they provide a bright green, wispy ground cover.
The perennial underground rhizome sends up both fertile and non-fertile stems. Horsetails incorporate silica in their cell structure, more than most vascular plants.
