Gender Ayuga, or (Ajuga), has about 40 species-herbaceous perennial and annual plants. Ajuga is characterized by tubular flowers with a protruding lip, collected in erect complex spike-shaped inflorescences with a sequential alternation of flowers and leaves. Dark green leaves are ovate-oblong in shape. In culture, as a rule, only perennial species are distributed.

Flowers of one of the dwarf varieties 'Brock-bankii' is blue in color. Dark oval leaves with a serrated edge of A. pyramidalisare collected in rosettes. In May, blue or purple flowers bloom in dense complex pyramid-shaped spikes.

The most widespread in floriculture is the creeper (A. reptans), which grows on moist soils. This is a rhizomatous perennial with creeping and rooting shoots, erect peduncles up to 25 cm long. Leaves are whole oval at the edges, large-toothed, rosette - on long petioles, stem-sessile. Blue or white flowers-numerous, collected in a false whorl or false spike.
