DistributionEssentially throughout the mountains, lacking known records only from three counties, one or two of which may have elevations too low for it. It is a species of the higher mountains, generally over 4,500 feet elevation.

This is a Northern species, found across most of southern Canada, south to central PA and IA, and then in the Appalachians south to extreme northern GA.
AbundanceUncommon over 5,000 feet, and rare perhaps down to 4,500 feet or slightly lower.
HabitatThis is a species of high elevation forests, not necessarily found at seepages and other damp spots (at least as much as the similar S. amplexifolius is). It can occur in Northern Hardwood Forests, mixed spruce-hardwoods, and also into spruce-fir forests. Some sites can be in boulderfield forests, and it can occur in some shady seeps as well.

PhenologyBlooms from late April to early June, and fruits from late July to September.
IdentificationThis is a delicately attractive spring wildflower of the high elevations, owing to its bright pink flowers. It grows to about 18 inches tall, with a zigzag stem and a few branches off the stem. The alternate leaves are elliptical and have strongly grooved parallel veins. The leaves are clearly ciliate along the margins. At each leaf node, there is a small and strongly drooping bell-shaped flower on a long and very slender stalk, bright pink with red stripes, about 1/3-inch long. The quite similar S. amplexifolius has leaf margins generally smooth, white to greenish-white flowers, and the leaves are strongly cordate-clasping at the base. Observers spending a bit of time in spruce-fir forests of mixed spruce-hardwood forests can encounter this species every now and then, though it is far from a numerous species in the state.
Taxonomic CommentsOlder references named this as Streptopus roseus. The species is broken down into a handful of varieties, with the NC one being the nominate one -- S. lanceolatus var. lanceolatus.
