Cryptotaenia japonica, commonly known as Japanese honewort, is a perennial herb native to the understory of moist deciduous forests in Japan, Korea, Taiwan, and China. It typically grows to a height of 12-18 inches (30-45 centimeters) with a similar spread. The plant features dark green, triangular leaves and small, inconspicuous white flowers that bloom in the summer. While the flowers are not particularly showy, the foliage is valued for its culinary uses and ornamental qualities. Japanese honewort is rich in calcium and vitamin C, making it a nutritious addition to various dishes.

In cultivation, Japanese honewort is appreciated for its ease of maintenance and its ability to thrive in shady conditions, making it suitable for woodland gardens, shaded borders, and as a ground cover. It prefers consistently moist, well-drained soils and can tolerate a range of soil types, from clay to loam. Gardeners often use it as a garnish and root vegetable in Asian cuisine, enjoying its parsley-like flavor in salads, soups, and sushi. The green Kansai type and the white Kantō type are two regional varieties that differ in stem coloration and are both used in culinary applications. Care should be taken as it can spread vigorously in favorable conditions, potentially becoming invasive in some gardens.CC BY-SA 4.0
