Marsh horsetail is a primitive fern-like plant with distinctive jointed green stems that emerge in spring and persist through fall. It requires consistently moist to wet soil conditions and thrives in partial shade areas where other plants struggle. This ancient plant spreads slowly by underground rhizomes and produces spore-bearing cones rather than flowers.
In an HOA neighborhood
Marsh Horsetail takes more care to keep looking intentional in a front yard. Maintenance level: moderate. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Unusual prehistoric appearance may look unkempt to conventional tastes

Wildlife value
