Horsetail plants spread through both spores and underground rhizomes. They have a wide-spreading root system. This can be quite bothersome because even after you cut down the scouring rush, it easily grows back.

How does the horsetail plant reproduce?

Reproduction. Horsetails show a form of alternation of generations (a sexual phase alternating with an asexual one), in which each generation is an independent plant. Spores are produced in spore cases borne on stalks which form a fruiting, terminal cone on the fertile stem. … The prothallium is the sexual generation.

Where do horsetail plants grow?

When it comes to soil moisture, horsetail prefers soil that is at least moderately wet. It can even grow in standing water up to a depth of about 4 inches. Thus, it’s well-suited for rain gardens and other areas that may periodically flood.
