Green Carpetweed

Flat spreading mat is the first thing to notice, but the plant does not stop there. Stand back and the shape begins to explain itself: prostrate annual, whorls of narrow leaves, and small white flowers all working in the same season. The first community record behind this page came from Massachusetts, United States on 2026-06-15. That small record gives the profile a starting point, then the plant asks for a wider look.

Green Carpetweed (Mollugo verticillata) is easiest to approach through structure before story. Look for flat spreading mat, and whorled narrow leaves, and tiny white node flowers. One mark can mislead, especially around garden plants, weedy annuals, hybrids, or familiar common names. A useful field view includes the whole habit, one close detail, and the surrounding ground. That combination lets a reader compare Chickweed and Purslane without turning the page into a guess from color alone. ²

Range gives the plant another biography. The range profile follows source-backed records for america, angola to cape provinces, then places those layers beside reported GBIF observations. The colored layer is not a promise that every hillside, garden bed, or ditch holds the plant. It is a conservative outline of cited geography, while the dots show records that people and collections have reported. ¹

The ecological story lives close to the soil. Green carpetweed often uses bare, sandy, compacted, or recently disturbed soil where a low annual mat can grow before taller neighbors close the light. Above that ground layer, quick annual cover shapes what a careful observer might see: visitors at flowers, seeds moving, stems storing water or energy, or leaves returning organic matter to the surface. The plant is not a loose fact on a label. It is a small system with roots, neighbors, weather, and timing.

A final look returns to whorled narrow leaves and low mats on open ground. Compare the small plant with the soil around it, and a common weed becomes easier to read as a ground-layer neighbor.
