About

Ajuga pyramidalis is a clump-forming perennial that is semi-evergreen, characterized by its basal rosette of dark green foliage. In spring and early summer, it produces whorls of small, tubular flowers that can be either dark or pale blue, set against dark purple bracts. The flowers are arranged in a pyramidal spike, reaching a height of approximately 10 cm.
