Nardia japonica, commonly known as Pacific Spikewort, is a perennial herb native to moist forest floors found in alpine and subalpine areas in Japan, Russia Far East to the Pacific Northwest. It typically grows to a height of 2-4 inches (5-10 cm) and spreads out to form a dense mat. The plant features small, inconspicuous green flowers that are often overlooked due to their size and color. Pacific Spikewort is valued for its lush, carpet-like foliage that provides excellent ground cover in shaded garden areas.

Pacific Spikewort is appreciated for its low maintenance and ability to thrive in moist, shady conditions, making it an ideal choice for woodland gardens, shaded borders, and as a filler between larger plants. It requires consistently moist soil and does not tolerate drought well. While it prefers partial shade, it can also grow in full shade, making it versatile for various garden designs. It is not commonly afflicted by diseases or pests, but overwatering or poor drainage can lead to root rot.CC BY-SA 4.0
