"Perennial from a woody rhizome; stems erect, 3–6 dm, finely puberulent; lvs subsessile, often with smaller axillary ones, lanceolate to oblanceolate, 1–3 cm, entire; fls 3–7 in each upper axil, the clusters sessile or subsessile, ± secund, subtended by reduced lvs, forming a spike-like terminal infl; cal 6.5–8 mm, the lobes to half as long as the tube; cor blue (white) 7–12 mm, the median lobe of the lower lip 6 mm wide; 2n=12. Native of Eurasia, found here and there as a weed along roadsides and in waste places in our range. July–Oct."
