About Three-cornered leek
Allium triquetrum, commonly known as Three-cornered Garlic or Angled Onion, is a perennial herbaceous plant featuring lance-shaped leaves and bell-shaped white flowers that dangle in clusters. Its delicate appearance and early flowering make it ideal for path edges, woodland gardens, or as a wild plant in low-maintenance landscapes, though it can be invasive in suitable climates.
Native range

Care tips
It thrives in partial shade to full shade and prefers moist, well-drained soil. This is a highly adaptable plant, tolerating a wide range of conditions, but it favors soils rich in organic matter. Watering should be moderate, keeping the soil moist during its active growing period and reducing it once the foliage begins to yellow. Avoid planting it near areas where you don't want it to spread, as it can quickly colonize the ground.
