Your Guide to Penny Plant Care and Growing Tips
The penny plant, scientifically known as Hydrocotyle vulgaris or marsh pennywort, is a small aquatic or semi-aquatic perennial herb with distinctive round, coin-shaped leaves that resemble pennies.
What Is a Penny Plant
The penny plant belongs to the Araliaceae family and is characterized by its unique circular leaves that grow on long, slender stems. These distinctive leaves measure approximately 1-2 inches in diameter and feature a glossy, bright green surface with prominent veining patterns radiating from the center attachment point.
This versatile plant thrives in both aquatic and terrestrial environments, making it a popular choice for water gardens, terrariums, and indoor plant collections. The penny plant produces small, inconspicuous white or greenish flowers during summer months, though most gardeners cultivate it primarily for its attractive foliage rather than its blooms.
How Penny Plants Grow and Spread
Penny plants exhibit a creeping growth pattern through underground rhizomes and surface runners that allow them to spread horizontally across suitable growing surfaces. The plant sends out stolons, or horizontal stems, that root at nodes to establish new plants, creating dense mats of foliage over time.
In aquatic environments, penny plants can grow both submerged and emergent, with leaves floating on the water surface or extending above it. The root system develops fibrous networks that anchor the plant while absorbing nutrients from soil or water. This adaptable growth habit makes penny plants excellent ground cover options for moisture-rich areas and water features.
Provider Comparison for Penny Plant Sources
Several reputable nurseries and online retailers offer penny plants for home gardeners and aquatic enthusiasts. Home Depot stocks penny plants seasonally in their garden centers, particularly during spring and summer months when demand peaks for water garden plants.
Lowe's provides both in-store and online ordering options for penny plants, often bundling them with other aquatic plant varieties. For specialized aquatic plant needs, Petco maintains a selection of penny plants suitable for aquarium use, ensuring proper sizing and health standards for underwater environments.

Benefits and Drawbacks of Growing Penny Plants
Benefits of penny plants include their exceptional adaptability to various growing conditions, from fully aquatic environments to moist terrestrial settings. These plants require minimal maintenance once established and provide excellent ground cover that helps prevent soil erosion in wet areas. Their unique leaf shape adds visual interest to garden designs and water features.
Drawbacks include the plant's aggressive spreading nature, which can overwhelm smaller garden spaces if not properly contained. Penny plants may become invasive in some regions, requiring regular management to prevent unwanted expansion. Additionally, the plant's preference for consistently moist conditions means it may struggle in areas with irregular watering or drought-prone climates.
Care Requirements and Growing Conditions
Penny plants thrive in partial shade to full sun conditions with consistently moist to wet soil or water environments. The ideal growing temperature ranges from 65-75 degrees Fahrenheit, though established plants can tolerate brief periods of cooler weather. These plants prefer slightly acidic to neutral soil with pH levels between 6.0 and 7.0.
Regular watering is essential for terrestrial plantings, while aquatic specimens require clean, well-oxygenated water with minimal chemical treatments. Fertilization needs are minimal, as penny plants readily absorb nutrients from their growing medium. Pruning involves removing dead or damaged leaves and controlling spread through division of established clumps during growing season.
Conclusion
Penny plants offer gardeners and aquatic enthusiasts a versatile, low-maintenance option for adding unique foliage to various growing environments. Their distinctive coin-shaped leaves and adaptable nature make them suitable for water gardens, terrariums, and moisture-rich landscape areas. While their spreading habit requires management, the visual appeal and ease of care make penny plants worthwhile additions to appropriate garden settings.Citations
