What are the morphological characteristics of this plant?
Ajuga lobata has a creeping growth habit characterized by stolons that produce basal rosettes of deeply lobed, ovate leaves with serrated margins. The leaves typically exhibit a textured surface and can vary in color from deep green to reddish tones depending on environmental conditions. As the plant matures, it sends up upright flowering spikes that bear small, tubular flowers arranged in dense verticillasters. These blossoms are often blue or violet and emerge from the center of the foliage clusters. The overall structure allows the plant to form dense mats through its spreading rhizomatous or stoloniferous network.
What is the geographical distribution of this plant?
This plant is native to the subtropical and temperate regions of East Asia, specifically occurring throughout China, Japan, and Korea. It thrives primarily in moist, shaded environments found within forest understories and riparian zones. The species is often found at various elevations ranging from lowland valleys to mid-altitude mountain slopes. Its distribution is closely linked to areas with high humidity and consistent soil moisture. While its core range is restricted to these Asian territories, it remains localized to specific ecological niches within those countries.
How is this plant cultivated?
This plant requires well-drained, fertile soil and consistent moisture to thrive in partial shade or filtered sunlight.
Growers should plant it in areas where it can spread naturally without becoming overly invasive. Regular watering is necessary during dry spells to prevent the foliage from wilting. Mulching the base of the plants helps maintain soil moisture and suppresses competing weeds.
Periodic thinning can assist in managing its growth pattern within a garden landscape.

As discussed in a study, Ajuga lobata D. Don is a medicinal plant rich in 20-hydroxyecdysone (20E), alkaloids, and other active substances. The study utilized suspension cells treated with 0.15 mg/l ABA to analyze the regulation of 20E synthesis. A total of 154 genes were significantly regulated after ABA treatment, with 99 up-regulated and 55 down-regulated genes. These regulated genes included six differentially expressed genes in the ko00900 terpenoid backbone biosynthesis pathway, four in the ko00100 steroid biosynthesis pathway, and six in the ko00140 steroid hormone biosynthesis pathway.
