Pretty sure this is growing at Clowderwood — and that i’ve been pulling it up. I remember the spines.
"Our commonest North Carolina nightshade is the ubiquitous Horse Nettle (Solanum carolinense), found in large numbers everywhere in North Carolina. As the name implies, Horse Nettle has arrays of sharp, tough spines on the stems and middle leaf ridges. The flowers are larger than most nightshades and color can range from white to a light or deep violet. The berries turn bright yellow in the fall and winter, and stand out against the bare winter landscape." — https://bwwellsassociation.wordpress.com/2017/06/24/the-troublesome-and-often-dangerous-hairy-nightshade-solanum-sarrachoides/
