Allium thunbergii, commonly known as Thunberg’s Garlic, is a deciduous perennial herb native to grasslands, rocky slopes, and along stream banks in East Asia, particularly Japan, Korea, and China. It typically grows to a height of 0.8-1 feet (0.2-0.3 meters) and a width of 0.5-0.8 feet (0.15-0.25 meters). This plant forms clumps of narrow, grass-like leaves and produces umbels of star-shaped, vibrant pink to purple flowers in the fall, which are highly ornamental and attract pollinators.

Thunberg’s Garlic is valued for its showy flowers and ease of maintenance. It is often used in rock gardens, borders, and as an ornamental feature in herb gardens. It thrives in full sun to part shade and prefers well-drained soils, tolerating a range of soil types from sandy to loamy. While it requires medium amounts of water, it is relatively drought-tolerant once established. It is not commonly associated with serious diseases or pests, but overwatering can lead to bulb rot. Allium thunbergii is not typically invasive and does not have aggressive roots, making it a well-behaved addition to the garden.CC BY-SA 4.0
