String of Lemons (Senecio citriformis), 4-Inch Pot

String of Lemons (Senecio citriformis, also known as Curio citriformis) forms a compact cluster of plump, pointed leaves resembling tiny green lemons. Its blue-green foliage and branching stems add unusual texture to a bright windowsill or sheltered succulent display.

Points of interest

• Fleshy, lemon-shaped leaves taper to a pointed tip and may show a pale, powdery surface.
• Young stems grow upright in clusters; older stems can spread and lean outward rather than immediately forming long strings like String of Pearls.
• Leaf color, fullness, and surface texture vary with light, age, and growing conditions.

What ships and estimated mature size

You receive one rooted live plant in a 4-inch nursery pot. Pot size describes the container, not the cluster’s diameter. Exact height, stem count, and fullness vary naturally. Decorative terracotta pots and furnishings shown in styled photos are not included and are sold separately.

Established stems may reach approximately 6–12 inches long and spread outward into a wider cluster over time. Light, pruning, root space, and seasonal growth determine its eventual size; mature size is not the shipping size.

Care guide

• Light: Provide very bright light with gentle direct sun after gradual acclimation. Protect from sudden intense afternoon sun, especially behind hot glass. Widely spaced leaves and weak stems can indicate insufficient light.
• Water: Allow the potting mix to dry thoroughly through the root zone before watering deeply. Drain fully and empty the saucer. Do not water on a fixed weekly schedule or keep the soil constantly damp.
• Soil: Use a gritty, fast-draining succulent mix in a pot with drainage holes. Our Succulent & Cactus Soil Blend is sold separately; add pumice or another suitable mineral amendment if your conditions require faster drying.
• Temperature: Protect from frost, prolonged cold dampness, and extreme heat. A warm, bright indoor location or sheltered patio is suitable when weather permits.
• Humidity: Average household humidity and good airflow are appropriate. Avoid misting the leaves and enclosed humid terrariums.
• Feeding: Feed sparingly only while the plant is actively growing, following label directions for succulents. Our 2 oz Slow-Release Fertilizer for Houseplants & Succulents is sold separately. Do not combine full doses of fertilizers or feed stressed, very dry, or resting plants.
• Seasonal care: Growth can slow during temperature extremes. Reduce watering when growth pauses and the mix stays moist longer; do not force growth with extra water or fertilizer.
• Grooming: Handle by the pot to avoid bruising leaves or rubbing away their natural surface coating. Remove dead leaves gently and trim weak growth with clean tools.
• Repotting: Repot when crowded or drainage deteriorates into a draining container only slightly larger than the root ball. Keep stems above the soil line.
• Propagation: Healthy stem cuttings may root after cut surfaces dry and callus. Use a fast-draining medium and avoid keeping unrooted cuttings wet. Success varies.
• Pests and problems: Check leaf joints and roots for mealybugs. Isolate affected plants and use a labeled treatment, testing a small area first. Mushy or translucent leaves can signal excess moisture; assess the roots and drainage before watering again.
• After arrival: Unpack carefully, inspect the stems, and check moisture before watering. Gradually introduce stronger light and allow time to settle before unnecessary repotting.

Pet safety: Treat Senecio/Curio succulents as toxic if eaten. Keep away from pets and children and do not use as an edible plant.
