Asarum heterotropoides, commonly known as Okuezo-Saishin or Korean Wild Ginger, is an evergreen herbaceous plant native to the forest understories of East Asia, including China, Japan, and Korea. It is particularly adapted to the moist, shady conditions found in these regions. This slow-growing plant reaches a modest height of 0.3-0.5 feet (0.09-0.2 meters) and spreads 0.5-1 feet (0.2-0.3 meters) wide. The foliage is a deep, glossy green, providing a lush groundcover throughout the year. Its flowers, which bloom in spring, are brown and often hidden beneath the leaves, making them inconspicuous yet intriguing upon closer inspection.

Asarum heterotropoides is valued for its attractive foliage and its ability to thrive in shaded areas where other plants may struggle. It is often used as a ground cover in woodland gardens, shade gardens, and naturalized areas. While it is low-maintenance, it benefits from being planted in humus-rich, well-drained soil. It prefers consistent moisture but can tolerate drier conditions once established. Gardeners should be aware that it can be slow to establish but will gradually form a dense carpet of foliage. It is rarely bothered by pests or diseases, making it a trouble-free addition to the garden.CC BY-SA 4.0
