Dichondra argentea, commonly called silver ponyfoot, is a trailing, mat-forming perennial in the bindweed family (Convolvulaceae) prized for its shimmering, coin-shaped leaves densely clothed in fine hairs. Native to the arid and semi-arid landscapes of the southwestern United States and Mexico, it thrives in heat, sun, and lean, fast-draining soils. In containers and hanging baskets, stems can cascade 3–6 feet, forming a dramatic, silvery waterfall; as a groundcover, plants remain just a few inches tall, spreading to create a reflective, drought-tolerant carpet. Flowers are small and inconspicuous, so the plant is grown primarily for foliage effect. Its silvery pubescence reduces water loss and glare, making it ideal for xeriscapes, rock gardens, and coastal or urban heat islands. While often treated as a warm-season annual in cooler climates, it is perennial in frost-free regions. Good drainage is essential to prevent root rot; with modest water and fertilizer, it maintains a compact, luminous display through the hottest months.

How to care for Silver ponyfoot
Water
After establishment, water deeply and then allow the top 1–2 inches of mix to dry before watering again. In summer containers, this may mean 1–2 waterings per week, more often in wind and extreme heat, less in shoulder seasons. Always ensure rapid drainage; soggy media promotes root rot. Water at the soil level to keep fuzzy leaves dry, especially in humid climates. Dull, slightly cupped leaves signal thirst; persistent yellowing and limp, mushy stems indicate overwatering.
Light
Full sun (6+ hours) delivers the tightest habit and brightest silver foliage. In very hot inland climates, provide filtered afternoon shade to prevent bleaching or crisp leaf margins. Bright partial shade is tolerated but leads to looser, longer internodes and a greener cast. Indoors, give the brightest window (south or west) or supplement with 12–14 hours of strong grow light to maintain compact growth and color.
Nutrients
A light feeder by nature, Dichondra argentea performs best in lean, sharply draining media. Mix a small amount of slow-release, balanced fertilizer at planting, or feed with a dilute (quarter- to half-strength) complete fertilizer every 4–6 weeks during active warm-season growth. Avoid high nitrogen, which encourages lanky, greener shoots and reduces the silvery look. Flush containers with clear water monthly to minimize salt buildup, and skip fertilizing in cool, low-light months when growth naturally slows.
Temperature
Prefers 18–30°C (65–86°F) and excels in dry heat. It is not frost hardy; growth slows below 10°C (50°F) and foliage is damaged near 4°C (40°F). In USDA Zones 10–12 it can be perennial outdoors; elsewhere, grow as a warm-season annual or overwinter indoors in bright light above 10°C. Short heat waves above 38°C (100°F) are tolerated with extra water and light afternoon shade. Avoid cold, wet soils and ensure good air movement to reduce rot risk.
