Corydalis ambigua

Corydalis ambigua, commonly known as Japanese Corydalis, is a perennial plant native to the mountainous regions of Japan, Kamchatka, Khabarovsk, Korea, Kuril Islands, Manchuria, Primorye, and Sakhalin. It thrives in partial sun or shade with moist, light (sandy) to medium soil, making it adaptable but preferring cooler climates hardy from zones 5-9. This plant is notable for its edible roots, which can be used as a food source. One distinctive feature of Corydalis ambigua is its delicate appearance, reaching only about 20 cm in height, with light green foliage and small, nodding flowers that add ornamental value to the garden.
