Braun’s Giant Horsetail (Equisetum telmateia ssp. braunii) – immature

Horsetails are considered living fossils as fossil remains have been found going back to the late Paleozoic forests. In those days the plant reached close to 100 feet tall which would have been a real problem in our garden. Our horsetail reach about 4 feet when mature. They used to be a real pain in our veggie patch but persistent weeding has won the day. They still persist in the damper areas of the yard and are a real treat to watch them go through their changes.
