Horsetail 

CAN BE FOUND IN:

Horsetail 

Equisetum arvense 

APPEARANCE 

The horsetail has bunches of green stems with many whorled branches, resembling bottle brushes. In spring, these green stems are replaced by blunt-tipped brown ones.

RANGE & HABITAT 

Horsetails can be found almost everywhere around the world except Australia and New Zealand. They live in moist places like wet grasslands, wet woods, marshes or ditches. 

RECIPROCAL RELATIONSHIPS 

Horsetails are most closely related to ferns! They have pale brown fertile stems which form cones that send out spores to produce new plants in the spring. When these stems wither, bunches of infertile green stems that resemble bottle brushes appear. Horsetails are important for semi-aquatic ecosystems. Because they grow quickly and die quickly, their plant matter provides a food source for small organisms.  

While alive many small beings can live near or around these plants, and bears and moose even like to eat horsetails! However, despite the name, these plants are toxic to horses. Horsetails are not endangered, and in many cases are viewed as weeds. Farmers view horsetails as weeds because they can encroach on corn and soybean crops. 

For the Gwich'in people horsetail can be made into medicinal teas. This tea is said to help with bladder infections and kidney problems. Squamish people have used horsetails as straws to drink from.
