Whorled marsh pennywort is a low-growing native groundcover with distinctive circular leaves arranged in whorls around the stem. This moisture-loving perennial thrives in wet areas and produces small white flowers during summer months. It spreads to form dense mats in consistently moist to wet soil conditions.
In an HOA neighborhood
Whorled Marsh Pennywort 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.
- Requires consistently wet soil that may create drainage concerns
- Low height and spreading habit can appear uncontrolled
- Specialized marsh plant may look out of place in typical landscaping
Wildlife value
