| Distribution | Mountains only, so far as is known. First collected by E. Schell in 1987 in Mitchell County; then in 2010 by Derick Poindexter in Alleghany County. A collection from Iredell County by Mordecai Hyams conceals the plant within a packet; thus the ID cannot be checked online. The native/alien status of NC plants is unsettled; Weakley (2022) considers it as not native in the East.
Native of Europe; in N.A. Greenland to AK, south to NC, AR, CO, CA. | |
| Abundance | Very rare. As it is generally considered to not be native in the eastern U.S., this species is no longer considered as a Watch List species (W4) by the NCNHP (in late 2022). | |
| Habitat | Roadside brick walkway (Alleghany Co.); gravel parking lot on Roan Mountain (Mitchell Co.). | |
| Phenology | Flowering and fruiting May-September. | |
| Identification | This species is tiny in stature and easily overlooked. It is very similar to the common native "belly plant" S. decumbens, but the small white flowers have 4 petals and stamens (vs. 5 in S. decumbens). | |
