Key Features & Benefits
- Heart-Shaped Foliage: Features small, fleshy, heart-shaped leaves with a marbled, silver-green pattern on top and a purplish tint underneath.
- Tuberous Roots: Stores water in small bulb-like tubers along its root system and stems, making it semi-drought-tolerant and forgiving if you forget to water occasionally.
- Compact Footprint: Perfect for small spaces, shelf edges, or hanging baskets where its long vines can cascade downward.
- Easy Propagation: Stems root readily in water, soil, or by placing the aerial tubers directly onto moist potting mix.
Care Requirements
- Light: Thrives in bright, indirect light. Needs some direct morning sun to maintain vibrant leaf coloration and variegated pink tones. Too little light leads to leggy stems with wide spacing between leaves.
- Watering: Treat like a succulent. Allow the top 2/3 of the soil to dry completely between waterings. Use the "squeeze test": if the leaves feel firm, don't water; if they feel soft or slightly pliable, give them a deep soak.
- Soil & Potting: Requires a fast-draining potting mix (e.g., 50% standard potting soil mixed with 50% perlite or pumice). Pots must have drainage holes to prevent root rot.
- Temperature & Humidity: Prefers temperatures between 65°F–80°F (18°C–27°C). Tolerates average household humidity well.
