General Information
A perennial herbaceous plant, with sparsely leafed stems 15 to 30 centimeters (cm) (6 to 12 inches) tall arising from a woody root crown. The leaves are very narrow with a smooth margin, 10 to 35 millimeters (mm) (0.4 to 1.4 inches) long and, usually, less than 2 mm (0.1 inch) wide. The leaf blades are alternately arranged on the stem and, for the most part, are attached directly to the stem without a petiole. The flowers of S. argillacea have petals that are pale lavender to whitish with prominent purple veins and measure 8 to 11 mm (0.3 to 0.4 inch) long and 3.5 to 4.5 mm (0.14 to 0.18 inch) wide. The entire flowers are about 1 cm (0.4 inch) across in full anthesis and are displayed in a raceme of 3 to 20 flowers at the end of the plant’s leafy stems (Welsh and Atwood 1977, Rollins 1982, Welsh et al. 1987).
