This skullcap, which could not be identified, belongs to the Lamiaceae family and displays the characteristic habit of the genus: erect stems, opposite foliage with light green, bright, crenate oval leaves, and tubular bilabiate flowers with two distinct lips.
The visible flowers are a pale lilac-blue, almost washed-out sky blue, with the lower lip lighter to whitish. The densely hairy calyces are tinged green and slightly purplish. The general habit, foliage texture, and flower size suggest a taxon of temperate Asian origin.
Most skullcaps of this type appreciate well-drained soil, a sunny to semi-shaded exposure, and moderate humidity in summer.
