Equisetum arvense, the field horsetail or common horsetail, is an herbaceous perennial plant in the Equisetopsida (the horsetails). Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests.
Here is out second weed friend: the thistle. They are very prickly so one needs gloves to pick them. These prickles are an adaptation that protects the plant from being eaten by herbivores. If you let them grow they will make purple / pink flowers.
Our third frenemy is: reed! Also known as phragmites. This one in the photo is small but they grow so fast and so tall. Apparently they are edible too: The young shoots can be consumed raw or cooked. The hardened sap from damaged stems can be eaten fresh or toasted. The stems can be dried, ground, sifted, hydrated, and toasted like marshmallows. The roots can be prepared similar to those of cattails. Should we try?
