Geum japonicum, known as Asian herb bennet, is a yellow-flowering perennial plant native to North America and East Asia, especially Japan. It may be synonymous with Geum macrophyllum, the North American flower. As a traditional herbal remedy it is known as an astringent and used in poultices. However, in recent years, the Thunberg variant has received attention for other possible medical uses.

🌳 Yellow avens possesses a notable capacity to signal the presence of certain metals in the soil. This trait could be used in bioremediation and environmental monitoring, helping detect and manage soil pollution caused by heavy metals.

Care Guide

💧 Water
☀️ Light Full sun

Yellow avens grows best with abundant sunlight, though it can also tolerate moderate light. Native to sun-drenched habitats, the plant's health and growth depend on this level of illumination. Both excessive and insufficient light can negatively affect its wellbeing.

Ideal: Full sun
🌡️ Temperature 0–32.2°C

Yellow avens can tolerate a wide range of temperatures, but its distribution may still be restricted by specific combinations of moisture and heat. It does best in warm summers with sufficient rainfall or watering. Long stretches of cloudy, rainy weather or prolonged high temperatures increase the chance of Yellow avens dying. In winter, proper protection from cold can raise the plant’s survival rate.

Ideal temperature: 0–32.2°C

🌱 Fertilizer

The best time to fertilize Yellow avens is in early spring, when it is coming out of dormancy and entering a period of active growth. Fertilization supplies essential nutrients needed for healthy growth. Although Yellow avens has relatively low fertilizer requirements, applying fertilizer once a year can improve its survival and encourage better, longer-lasting flowers.
