Summary

Ajuga japonica, commonly known as Bugle, is an evergreen perennial herb native to the forest margins, grasslands, and open areas of Japan. It forms dense mats by spreading stolons and typically stands 8–20 cm (3–8 in) tall, including the flowers. Ajuga japonica blooms from late April to late May, showcasing light purple, tubular, and lip-shaped flowers that are 2–5 cm (0.79–1.97 in) long and emerge from the tips of the flower stems. The pinnate, heart-shaped leaves with serrated margins are also 2–5 cm (0.79–1.97 in) long and are arranged oppositely on the stem.

This plant is valued for its ground-covering ability, low maintenance, and attractive foliage and flowers. It is commonly used in garden borders, as underplanting for shrubs, and in containers. Ajuga japonica thrives in partial shade to full sun and prefers moist, well-drained soils. While it is adaptable to various soil types, it benefits from organic matter enrichment. It is important to avoid overly wet conditions to prevent crown rot. Ajuga japonica can be invasive in some regions, so gardeners should monitor its spread.CC BY-SA 4.0
