Delicate and slender-stemmed, this perennial can be upright or sprawling, and 2-20 in. high. Diamond-flowers or bluet stems form clumps and become branched in the upper portion. Its small but abundant flowers are pink or white, trumpet-shaped, four-lobed, and in clusters at the ends of stiff branches. Leaves are very narrow and thread-like with rolled margins.
Nigricans so named because the leaves turn black when dry.
