Description The plant is an annual or short-lived subshrub reaching 35–40 cm in length and is completely hairless. Its lower stems become woody and produce numerous thin, thread-like branches. The leaves are sparse and vary in shape along the stem, ranging from elliptical or lance-shaped on the lower parts to very narrow, almost needle-like leaves near the top.
The flowers are borne in small, loosely spaced clusters. The calyx is tubular, while the corolla is pale blue and about 10 mm long, with a narrow cylindrical tube. The plant has two fertile stamens and several reduced sterile stamens. The fruit is a small oval capsule containing tiny brown, finely textured seeds.
